Lockdown mode urged with avian flu outbreaks in Mississippi and Central Flyways.

 

A warning to tighten up biosecurity and reduce movement in and out of poultry houses was issued by Terry Conger, DVM, poultry health epidemiologist with USDA’s Animal and Plant Health Inspection Service (APHIS). The warning came as outbreaks of highly pathogenic avian influenza (HPAI) occurred along the Mississippi Flyway for migratory waterfowl. Earlier HPAI outbreaks were reported along the Atlantic Flyway, which can mingle with the Mississippi Flyway. 

Outbreaks in both areas involved commercial and non-commercial poultry operations. And recently, outbreaks were reported in the Central and Pacific flyways. “Migratory waterfowl and other wild birds play a major role in introducing the [HPAI] infection into flocks, and once in a facility, it can spread like wildfire through the movement of fomites,” Conger said. 

He spoke during a recent University of Arkansas Ag Research and Extension webinar on HPAI. 

     H5N1 strain involved. 

 The latest HPAI outbreaks in the US are caused by the serotype H5N1, known as the Eurasia strain. Conger said H5N1 is an ongoing, rapidly spreading strain that has been prominent in Europe, Asia and Africa. 

The first HPAI H5N1 outbreak in the Western Hemisphere occurred Dec. 23, 2021, in Newfoundland and has continued to spread into the US. “Due to the perpetual risk of HPAI from waterfowl, the only preventive tool we can rest our hopes on is stringent biosecurity,” Conger said. “Contract growers and non-commercial flock owners must buy into biosecurity to protect their individual flocks because HPAI is here,” he added. 

“Biosecurity must become a part of life if you oversee a commercial or backyard flock. It must be as automatic as eating and sleeping.” 

 Biosecurity breakdowns.

. While migratory waterfowl are the most common initial source of HPAI infection, human error is also responsible for spreading it into flocks through breakdowns in biosecurity. “Infection can occur by the movement of contaminated equipment, vehicles, service personnel, visitors and pests including rodents and insects,” 

Conger said. “Less common are domestic pigs and pet birds. “Once the virus is in a facility, it can move very quickly on shared equipment and contaminated clothing,” he said. “This is how it exploded in Minnesota and Iowa in 2015.” Personnel in commercial flocks who take steps to tighten up biosecurity are more likely to keep the virus out.

Model predicts cross-species contamination risk for farm animals.

 

A new mathematical model from US researchers reveals the high risk of cross-species disease spread on farms with more than one type of animal. According to the model developed by a team at North Carolina State University—and described in Veterinary Research—biosecurity efforts focused on the top three per cent of farms in a particular contact network may significantly cut back cross-species disease dissemination. 

 “Most disease-prevention programs focus control and prevention measures on one species; however, it is well known that cross-species transmissions occur,” A/Prof Gustavo Machado said. “For example, foot-and-mouth disease can be transmitted among all ungulate species. And all of these farms are connected—they sell and share animals all the time.” 

 The researchers created a stochastic mathematical model that described the ‘connectedness’ of farms in one area of Southern Brazil. 

The model included three years’ worth of data for a population of 90 million animals and traced over 1.6 million animal movements between farms, such as animal sales and grow-finishing movements. 

 The model simulated disease outbreaks that began in cattle, pigs, and small ruminants (i.e., sheep or goats), respectively, in order to determine the likelihood of cross-species contamination in each case. They ran 1000 distinct simulations 100 times each to identify,continue

How sneezing hamsters sparked a COVID outbreak in Hong Kong.

How Sneezing Hamsters Sparked a COVID Outbreak in Hong Kong Hamsters are only the second species known to have spread SARS-CoV-2 to humans

 

Pet hamsters probably carried the Delta variant of SARS-CoV-2 into Hong Kong and sparked a human COVID-19 outbreak, according to a genomic analysis of viral samples from the rodents. 

The research confirms earlier fears that a pet shop was the source of the outbreak, which has so far infected about 50 people and led to the culling of some 2,000 hamsters across the city. 

Hamsters are highly susceptible to SARS-CoV-2 and so are a popular model for studying the virus. But the Hong Kong study — posted online as a preprint1 and yet to be peer reviewed — is the first to show that hamsters can become infected outside the laboratory, and that they can pass the virus on to both other hamsters and humans. 

 Hamsters are only the second animal known to be able to infect people, after mink. In late 2020, small outbreaks of COVID-19 in people in Denmark and the Netherlands were linked to farmed mink, sparking panic and mass culls. 

 The latest study points to the pet trade as a route for viral spread, says co-author Leo Poon, a virologist at the University of Hong Kong. But “to be fair to the hamsters”, people are still much more likely to be infected by each other than by pets, he says. 

             NEW ROUTE FOR VIRAL SPREAD .

Nevertheless, it is important to monitor the pet trade closely, says Marion Koopmans, a virologist at the Erasmus University Medical Center in Rotterdam, the Netherlands. SARS-CoV-2 could continue to circulate in animals, evolving in unexpected ways, and then spill back into people, she warns, adding that “we don’t need more surprises with this virus”. 

 Hong Kong has maintained a strict zero-tolerance approach to COVID-19, so when a 23-year-old pet-shop worker tested positive for Delta on 15 January, Poon says it was “a bit bizarre”. The last time the city had seen Delta in the community was in October. 

 Within days, public-health officials had swabbed more than 100 animals at the pet shop and another 500 at the warehouse supplying it. They detected SARS-CoV-2 viral RNA or antibodies against the virus in 15 of 28 Syrian hamsters (Mesocricetus auratus), but in none of the dwarf hamsters, rabbits, guinea pigs, chinchillas or mice. 

 The researchers then analysed genomic sequences of samples collected from 12 hamsters and the first 3 infected people, including the pet-shop worker and a visitor to the shop. 

All of the samples contained a variant of Delta that had not previously been detected in Hong Kong and probably originated from the same source. 

 The team also noticed some diversity in the sequences, and concluded that the hamsters were probably first infected in November, before their arrival in Hong Kong, and that the virus had been spreading undetected among the animals, accumulating a few single-nucleotide mutations along the way. 

  JUMPING BETWEEN SPECIES The pet-shop worker and visitor were probably infected on separate occasions, and Poon says there could have been more jumps. 

Most surprising, he says, was that even after replicating in hamsters, the virus could still “transmit between humans quite effectively”.

Agribusiness :How to use circular economy to boost productivity in dairy value chain.

 

The circular economy is a new approach to the reduce-reuse-recycle model.

 

The circular economy has the added advantage of not only making products or by-products go back to production cycles it ensures sustainability of business and environment.

 

 What is the circular economy and how can this be implemented in the dairy value chain?.

 

  Circular economy is a model of production /consumption that involves the use, reuse and recycling of products, byproducts and materials of production to create a sustainable cycle of production and consumption.

Dairy industry is based on circular production cycles with the dairy and Agri-food sector sharing a history that dates back to early dairy business.

 

The use of pasture land for feeding dairy cows, by growing different crops on rotated pieces of land, by fertilizing the land with animal’s waste and at the same time keeping animals as a long-term stock of nutrients, the sector builds on the long and deep knowledge of humankind.

        

Dairy cows have a unique ability to consume non-edible feed stocks and turn them into a very nutritious protein that humans can eat.

 

 The concept of the circular economy is to look at the cycle of production and identify points or areas in the cycle that can be redirected into the production phase to achieve the following:

 

 

1)    Reduce waste and the resultant pressure on the environment by creating clean alternatives.

2)    Reduce cost of production by reusing some inputs or by-products thus increasing profit margin.

 

3)    Create new channels of production by creating new viable products from existing products.

 In the dairy industry the circular economy is employed in the following ways:

 

1)    The waste from cows provides a source of fertilizer that can be put back into the farm, it is also fed into bio digester thus helping to curb methane emissions and produce a renewable energy source for the farm.

 

2)    Cows utilize the grazing lands  as well providing a source of milk and natural fertilizer, and at the end of life the cow can be converted into a variety of products, such as beef, pet food, and leather goods

 

3)    Whey, a co-product of the cheese-making process was once put onto land, or fed to pigs, but is now being used as high-value protein concentrates for specific human nutrition (sports, infants, and the elderly) in a growing market, and in special cases, for young animal feed.

 

4)    Nutrient recycling from waste water treatment plants sludge from dairy processing: digestate (sludge output from a digester) e.g. from digesting manure or food waste is of outmost importance for a circular economy to function properly (whilst guaranteeing and safeguarding food safety and animal health).

 

5)    Waste to electricity: using the biogas from the digester to produce electricity. The heat will be redirected to the stalls to keep the facility warm, thus also increasing productivity at reduced cost.

 

6)    Cow mats produced from hide also boosts productivity by increasing the comfort of the animals thus stimulating more milk production.

Cassava exports, prices jump on surging china demands.

  

Vietnam exported $256 million worth of cassava and cassava products in the first two months of the year, a 77.9 percent year-on-year increase, with China being the biggest market. 

 China accounted for over 95 percent of exports in January, with prices rising by 69 percent year-on-year to $242.2 per ton. 

 According to the Vietnam Cassava Association, a number of local processing factories face a short supply though the harvest season has begun. 

 Local prices are expected to reach record levels by the end of the harvest since most of it would be exported to China at high prices, which have reached $270 FOB at Quy Nhon Port. 

 China has huge demand for cassava as a replacement for corn, whose global prices are surging, to feed pigs.

Covid-19 and African swine fever(ASF)..

There are some striking similarities between the Covid-19 outbreak and African Swine Fever.

 A different virus has taken over the headlines now ,sharing the spotlight with African Swine Fever dominating the columns online and in the paper, the Corona virus disease 2019 (Covid-19).

 The Corona virus does not affect swine but indirectly affects the swine business. There is one major difference between ASF and Covid-19, this is the fact that ASF leads to the death of virtually all pigs whereas Covid-19 would in most cases not be lethal, meaning that proper health care can play a role as well.

   Learn all you need to  know about ASF from  experts. Join us.

                                     

Lessons learnt with regard to Covid-19 and ASF, lessons learnt are threefold.

First, it’s never too early to start thinking about a virus at the other side of the planet (look at this Danish example).

Secondly, let’s hope the millions pumped into the vaccine business to find a good Covid-19 vaccine somehow lead to a positive spin-off for pig vaccine development too.

 Thirdly, countries reporting many outbreaks are not the ones having the largest problem – they in fact are the ones sharing the most information.

 The striking similarities between Covid-19 and ASF. 1) The sudden panic . 2) The absence of a vaccine now. 3) Reporting of outbreaks.


  Reporting the outbreaks is very important as there is a link between countries reporting and number of cases in such  countries.

There are many websites around the world keeping us posted about the progress of the Covid-19 virus, about the number of people infected, the number of people that died of the virus and mortality percentages, showing interesting maps.

Interestingly, however concrete those numbers appear to be, it’s good to ask questions about the ‘why’ and ‘how’ behind those figures and that there is a parallel with African Swine Fever outbreaks which Pig Progress has been following intensively.


 For example – can people be infected with Covid-19 yet barely notice it? If so, that would mean that the virus could be much more widespread than is actually reported, meaning that the real mortality figure is much lower.

 Extremely interesting in this context I find is the way in which authorities have behaved in recent years with the reporting of ASF outbreaks.

 It is important to understand that accurately reporting ASF outbreaks depends on a gigantic mix of components, just to name a few: 1)Availability of test kits.

 2)Presence of necessary diagnostics infrastructure, including labs.

3)Availability of funding for affected farmers.

 4)Availability of educated manpower to process all information.

 5)Knowledge about the virus.

 6)Sense of responsibility for others.

 7)Cultural attitudes with regard to transparency in case of large problems.

 8)Corruption.

 9)Protection of export interests.

 As regard to ASF, some countries have reported more outbreaks than others, in different frequencies, in different intensity, on different levels as well. Some did not report anything at all – or only occasional outbreaks.

Using the history of reporting , to have a reliable idea as to what numbers might be credible beyond doubt with regard to reporting corona virus, I’d first look at the countries that have been reporting ASF frequently, swiftly and without hesitation.

Pig producers considers stopping castration.

 Pig producers considers  stopping  castration.

10 pig producers’ organisations in Western France are considering to stop castrating piglets as from December 31, 2021.

 The organisations represent a respectable part of the country’s producers. The proposal of the 10 organisations is a reaction to a decision by Didier Guillaume, France’s minister for agriculture and food.His aim is to improve animal welfare in France’s pig industry and one of his measures is that, after 2021, castration will only be allowed when anesthetics are applied.


 The intention is that the basis price for pigs will be adjusted. The collectives feel that gilts as well as entire boars will form the reference for pig prices as from 2021.

 The slaughterhouses will become the place for checks whether or not carcasses will have boar taint, these could be detected by sniffing at the slaughter line by humans. Additional costs of these checks will be carried jointly by the pig farms that stopped castrating.

Medium-chain fatty acids: Protecting pigs from pathogens.

Global movement of feed ingredients calls for an in-feed disease mitigation strategy.

Feed and feed ingredients have the potential to harbor devastating bacteria and viruses like porcine epidemic diarrhea (PED) virus, porcine reproductive and respiratory syndrome (PRRS) and African swine fever (ASF).


The bacteria and viruses can be transmitted in feed – eventually making their way through the pig’s digestive system and replicating, causing infection.

 The global movement of feed ingredients and commodities increases the risk of introducing disease through ingredients when sourced from areas of active disease pressures.


The risk of global disease transmission reinforces the need for an in-feed mitigation strategy to help guard against disease threats.

 Medium-chain fatty acids (MCFAs)  have proven to be a useful biosecurity tool, essentially acting as security guards to protect pigs from bacteria and viruses.

The coconut oil  contains a (medium chain fatty acid}begin working in feed, before pigs consume it, to reduce the feed’s pathogen load. After feed consumption, it continues to work inside the animal to weaken pathogens in the digestive tract. Learn how coconut oil in your pig diet can act as a biosecurity tool .

The coconut oil kills bacteria in feed before the pig consumes it and also prevents the replication of bacteria inside the pig.

This is how it kills bacteria:1)Degrade the bacterial cell membrane.

 2)Dissociate into the bacterial cell, causing the pH inside the cell to drop.

 3)Block DNA replication of bacterial cells. In case of viruses with envelopes this is how coconut oil protects the pigs.

"African Swine Fever is a man-made disease".

"African Swine Fever is a man-made disease".If there is one take-home message to report after having spoken to two of the leading scientists on African Swine Fever, it should be that the major threat with regard to the virus is not the virus itself, but how humans deal with it.

 Dr Klaus Depner, head of the International Animal Health Team at the Friedrich-Loeffler-Institut (FLI) on the island Riems in northern Germany, has to admit that even he as expert needed some time to understand the disease. How does the virus spread?Wild boars shed the virus mainly when they are very sick and in the final stage of the disease.

When the animals have high fever it’s in their character to stay where they are, and they are certainly not going to walk very far when they feel bad. So what we have here is a virus that is very stable in its environment without fast movement. It neither dies out, nor moves. Undisposed carcasses of infected wild boars remain infectious for a long time in the environment and become a source of infection for healthy animals.


 The human role Still, ASF did spread from the Caucasus until the Baltics and Poland. The question now is how. Soft ticks and insects are unlikely to have transmitted the virus, the scientists say. In fact, they have little doubt identifying about the real reason behind most of the ASF outbreaks: negligence.
Participating in recent ASF monitoring missions in Eastern Europe, Depner has a good idea of what has likely occurred. He says, “Often it was a matter of human misbehaviour. What happened is that infected meat made it to the market.


When many pigs started to die, they were sent to slaughter. Pig prices dropped, cheap meat entered the market and the meat made its way into homes – and into suitcases. This is how the virus dispersed. The virus spread along the main roads, the transport routes. This spread bears a 100% human mark.” more.

VETERINARY MEDICINE:Poultry, pigs not susceptible to COVID-19.

German researchers: Poultry, pigs not susceptible to COVID-19.Scientists in Germany have confirmed that chickens and pigs are not susceptible to COVID-19. Researchers around the world have been trying to find out whether SARS-CoV-2, the virus which causes COVID-19, can infect other species after it was understood to have originated from bats. Germany’s Friedrich-Loeffler-Institut started infection studies in chickens, pigs, fruit bats and ferrets several weeks ago, inoculating animals nasally with SARS-CoV-2 to mimic the natural route of infection in humans. While early results indicated fruit bats and ferrets are susceptible to SARS-CoV-2 infection, pigs and chickens are not.The researchers said they tested chickens and pigs due to the close contact they make with humans. Tests were carried out to discover whether animals become infected, whether the pathogen replicates, and if the animals show symptoms of the disease.“Under experimental conditions, neither chickens nor were found to be susceptible to infection with SARS-CoV-2,” the institute said. “According to the current state of knowledge, they are not affected by the virus and therefore do not pose a potential risk to human health.” The final results are expected at the beginning of May. The German study follows research carried out in China that investigated the susceptibility of ferrets and animals in close contact with humans to COVID-19. Scientists at the Harbin Vet Research Institute found that SARS-CoV-2 replicates poorly in dogs, chickens, pigs, and ducks but efficiently in ferrets and cats. #COVID-19 #coronavirus #veterinarymedicine #onehealth.

How to protect a pig farm from African Swine Fever.(ASF).

 How to protect a pig farm from African Swine Fever.(ASF).


ASF is all about contact ASF is spread by contact. Far less by the pig breathing the virus in as in Classical Swine Fever, so it should be easier to prevent and control.

 Think ‘contact’ in everything you plan to do and subsequently carry out on the premises. The contact is not just pig to pig, but what we humans do by allowing the ASF virus in through contact on the clothing equipment, vehicles, food deliveries, breeding stock and every other visit by an ‘outsider’ to or into your vulnerable farm premises.

 1) Keep everybody off your farm You will need discipline and tact to do this effectively. Quite brutally, you do not know where they have been! So do not risk it. The only permissible person as routine is the pig veterinarian and of all people he should take the necessary precautions.

Even so, do not allow his vehicle on to the farm. Have a parking spot outside the perimeter and if necessary, help carry his equipment in for him.

 There will be skilled artisans of course, electricity, roofing, plumbing, etc. who will need access. Keep their vehicles off the farm too and make it clear beforehand (for the sake of good relations) that they will have to use farm overalls and footwear and need their equipment mist-sprayed.

 2)An unbreakable farm perimeter defense. For the delivery of replacement stock (semen is safer than live pigs) and the collection of finished pigs, have designated areas on or just outside the farm perimeter.

On no account allow ‘helpful’ drivers (offering to assist with the loading) on to the premises. The same with bulk or bagged food and supplies.

 As soon as you can, set up food reception bulk bins using your own inlet hoses, not theirs; a covered site for bags and other bulky deliveries. All 3 on the farm boundary, for later inward transmission by your own staff, never theirs.

AGRIBUSINESS: 4 piglet parameters for lifetime performance.

             AGRIBUSINESS: 4 piglet parameters for lifetime performance.

 Genetic selection is leading to larger litters of piglets born with lowered levels of physiological maturity. As this trend amplifies an evolutionary strategy in swine favouring survival of the fittest, it presents negative performance and animal welfare implications.

 Sow Peripartal Syndrome is a complex web of interactions affecting sows and piglets during the peripartal period. At least four parameters are present at birth that can ultimately determine piglets’ lifetime performance.

The following is an update on research underway to managing the syndrome. Alive at birth While genetic selection has increased the total number of pigs per litter, the number of pigs born alive has not increased at the same pace.

AGRIBUSINESS:    Heat stress in pigs and its effect on the gut. 


 Heat Stress is a physiological response to high environmental temperatures, where the animal is out of its thermo-neutral zone and can no longer effectively regulate its body temperature. Consequently, animal health, well-being and performance are negatively affected.

 

VETERINARY MEDICINE: Dogs can be a potential risk for future influenza pandemic.

VETERINARY MEDICINE: Dogs can be a potential risk for future influenza pandemic. Dogs are a potential reservoir for a future influenza pandemic, according to a new study. The study demonstrated that influenza virus can jump from pigs into canines and that influenza is becoming increasingly diverse in canines. Influenza can jump among animal reservoirs where many different strains are located; these reservoirs serve as mixing bowls for the genetic diversity of strains. Pandemic influenza occurs when viruses jump from animal reservoirs to humans; with no prior exposure to the virus, most people do not have immunity to these viruses. The main animal hosts for influenza are wild birds, poultry and other domestic birds in a species pack; swine; and horses. Fifteen years ago, researchers documented an influenza virus in a horse jumping into a dog, and this created the first circulating canine influenza viruses. Five years ago, researchers identified an avian-origin H3N2 canine influenza virus circulating in farmed dogs in Guangdong, China.

AgriProtein, a startup produce maggots from waste to feed animals.

 AgriProtein ,a startup grows maggots from waste to feed animals. AgriProtein. The world urgently needs new sustainable sources of protein.

 A growing population, scarce water and land resources, and declining natural fish stocks make this more critical than ever.

 Industrial farming of chickens, pigs and fish relies on protein from two sources: land-based grains and marine captured fish meal.

Agricultural protein requires vast amounts of land and water, while the sea-caught alternative has material consequences for marine life. Increased global food demand and environmental limits have caused prices of both protein sources to soar in recent years.

  AgriProtein ,a startup grows maggots from waste to feed animals. AgriProtein is leading a new industry called nutrient recycling.

 It is a business that grows maggots from waste collected from markets,farms, households and businesses. The maggots are processed into a highly nutritious protein supplement that substitutes fish meal in animal feed.

 Using fly larvae fed on existing organic waste, AgriProtein has developed and tested a new large scale and sustainable source of natural protein.


 The bio-conversion process takes organic waste streams from food factories, supermarkets, farms and restaurants, and recycles these into valuable products: an insect based complete protein – MagMeal™, an extracted fat – MagOil™ and a rich residual soil conditioner – MagSoil™. Agriprotein.

Cows and pigs are great livestock, but they can also make you really sick

Cows and pigs are great livestock, but they can also make you really sick.Sometimes in this world, it’s the little things that can cause the most problems. Really, really little things. This is especially true for anyone working around or with livestock in Maine, according to Dr. Anne Lichtenwalner, director of the University of Maine Veterinary Diagnostic Laboratory and associate professor of animal and veterinary science. Some farm animals can actually “share” parasites with their human companions. “There are actually just a handful of parasites that I worry about,” Lichtenwalner said. “These are critters that are parasites that can live inside you and tend not to be fatal, but that can cause some ugly surprises.” The two most common zoonotic parasites — those that can transfer from animals to humans — in Maine are Ascaris suum and Cryptosporidium. “You are protected by your innate and acquired immune system,”

Bacteria carried by unneutered dogs could put pregnant women at risk.

Bacteria carried by unneutered dogs could put pregnant women at risk. Intact dogs can carry Brucella canis bacteria, which can cause flu-like symptoms in people and pose risk to a pregnancy, according to a study in Emerging Infectious Diseases. Brucellosis infections can cause miscarriages in animals and are associated with fetal problems in pregnant women, and the CDC says pregnant women who may have been exposed to the bacteria should consult their health care provider. A bacteria carried by dogs that haven't been neutered can produce flu symptoms in humans and potentially jeopardize a pregnancy, a new study suggests. Brucellosis infection is most commonly spread by livestock like sheep, cattle, goats and pigs. But a strain of the bacterium carried by dogs -- Brucella canis -- could be widespread in humans, warned lead researcher Martha Hensel, a veterinarian with Texas A&M University. B. canis is carried by dogs that can still reproduce, Hensel noted. It's not clear exactly how the bacteria might spread to humans, but it's most likely passed through contact with reproductive organs or urine. People who regularly handle such dogs -- vets, dog shelter employees, dog breeders -- are most at risk for contracting brucellosis, Hensel said. However, pet ownership is a likely risk factor for infection, particularly for young children and people with compromised immune systems, Hensel and her colleagues explained. The researchers highlighted some case studies: 1) A 3-year-old New York City girl came down with brucellosis in 2012 after exposure to an infected puppy recently purchased from a pet store. 2)Several people with HIV have developed brucellosis in recent years, all linked to intact dogs they owned that were later diagnosed with B. canis infection. more

'Green'-feed: Industrial microbes could feed cattle, pigs, chicken.

'Green'-feed: Industrial microbes could feed cattle, pigs, chicken. Deforestation, greenhouse gas emissions, biodiversity loss and nitrogen pollution . Today's agricultural feed cultivation for cattle, pigs and chicken comes with tremendous impacts for the environment and climate. Cultivating feed in industrial facilities instead of on croplands might help to alleviate the critical implications in the agricultural food supply chain. Protein-rich microbes, produced in large-scale industrial facilities, are likely to increasingly replace traditional crop-based feed. A new study now published in the journal Environmental Science & Technology for the first time estimates the economic and environmental potential of feeding microbial protein to pigs, cattle and chicken on a global scale. The researchers find that by replacing only 2 percent of livestock feed by protein-rich microbes, more than 5 percent of agricultural greenhouse gas emissions, global cropland area and global nitrogen losses could each be decreased.

How to detect foot and mouth disease with simple environmental sampling.

How to detect foot and mouth disease with simple environmental sampling. Simple sampling method eases identification of foot and mouth disease outbreaks.

Sampling the environment is an effective way to detect foot and mouth disease, according to a paper published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. 

 The sampling method, swabbing environmental surfaces where livestock are kept, can be easily performed and can detect viral genetic material that can persist in the environment well beyond the time when livestock cease manifesting clinical signs of disease.

 Unlike taking clinical samples, those taking samples need not be able to recognize clinical signs of foot and mouth disease. Thus, smallholder farmers in developing countries could take the samples in lieu of veterinarians. 

 Foot and mouth disease is caused by a member of the genus, Aphthovirus. It causes blisters in the mouths and on the feet of cattle, goats, pigs, and other cloven-hoofed mammals. The virus contains a single strand of RNA that encodes its genome.

 Humans are not susceptible to foot and mouth, and the disease generally doesn't kill animals. However, it can greatly reduce milk and meat production, creating a hardship for smallholder farmers. 

 Foot and mouth disease can also have a major impact on a national economy. 

In foot and mouth disease-free countries, an incursion of foot and mouth disease can cause significant losses due to imposed grade restrictions and subsequent control measures required to eradicate the disease.
