HPAI prevention requires ‘buckle-up’ mentality to biosecurity.

 

HPAI prevention requires ‘buckle-up’ mentality to biosecurity.  The only option for poultry farms to prevent an outbreak of highly pathogenic avian influenza (HPAI) is 100% adherence to biosecurity rules. 

 “You can be doing 99% of [biosecurity] correctly and somebody does one thing wrong and brings the disease into the farm,” reported Bret Rings, DVM, Cobb-Vantress. “Think of biosecurity as a chain — it is only as strong as the weakest link.” 

 Strengthening biosecurity requires building a culture that makes following protocols second nature for everyone on the farm. “It’s like a seat belt; it is protection that you use and do all the time because you never know when you will need it,” Rings said. “You never know when you will be exposed to HPAI and you need to protect your flock.” 

                Build a biosecurity culture.

 A biosecurity culture must be built into how producers do business every day, Rings explained, during a recent HPAI risk webinar hosted by the University of Arkansas. He recommended using communications and training to help transfer the importance of biosecurity to growers and farm staff: Communications – Biosecurity protocols must be communicated to everyone on the farm, from the grower to hourly employees.

The protocols should be clear, simple and based on scientific data. It’s important for everyone to understand protocols are to be followed consistently and with no exceptions. “You need to find creative ways to share that information, whether by a personal conversation, a one-page document, poster or meeting where you discuss the importance of biosecurity in today’s environment with HPAI taking place,” he said. 

 Training, training, training — In addition, regular training helps build the culture while reinforcing the correct way to follow biosecurity protocols. Rings suggested using small meetings or get-together with farm staff for the training. 

The training also shows staff that biosecurity is a priority. “It comes down to some persuasion and motivation,” he added. “Emphasize to farm workers that biosecurity is of utmost importance. The threat is real; it can happen to anyone, and it does.

BIOSECURITY PROTOCOLS ON A PIG FARM.

 BIOSECURITY  ON THE PIG FARM


. .

 Bio security both internal and external ensures health of pigs on the farm.The importance of biosecurity has been stressed and It is important to discern between external and internal bio security. 

External biosecurity deals with the strategy of keeping infectious diseases away from farms.

Internal biosecurity, however, revolves around the question how to prevent the spread of contagious diseases within the farm. Is this from pen to pen, from unit to unit or from house to house?

Whichever strategy is chosen, cleaning and disinfection procedures play a major role in internal biosecurity and more particularly in the prevention of disease propagation from one group of animals to the next.


BIOSECURITY ON THE PIG FARM.
 Cleaning  and disinfection procedures are applied by pig farmers all over the world, in both developed and developing countries.  However, they are based on historically grown routines, shaped over years rather than being based on well-considered protocols.

 Frequently, practices like these have led to sub-optimal technical results. Creating doubts as to whether the money spent on these protocols contribute to the farm's zootechnical and financial health status.

 Indeed, several crises in the industry have often led to cost-cutting measures related to these, whereas a well-designed plan for smart and consistent biosecurity, executed flawlessly, is nevertheless a cornerstone of good biosecurity practices.

 Smartphone app assisting pig farmers :Cid Lines's new tablet and smartphone app is a  prevention Cost Calculator developed to assist pork producers on how to make the right management decisions for their sanitation protocols.

 The app serves as a calculation tool using   the  farm data it will give a perfect insight into the volume of detergent and disinfectant needed  to create  a personalized hygiene protocol.

Tools to aid pig producers with biosecurity and management.

Tools to aid pig producers with biosecurity and management. Biosecurity is not only a matter of disinfecting and fencing,it is a matter of mentality.There is a need to be aware of how pathogens can enter a farm can make pig producers more prudent about what to pay attention to. When planning a control plan for a disease such as Porcine Reproductive and Respiratory Syndrome – PRRS it is essential to follow a systematic approach like the 5-step process. Step 1 and 2 – aim at setting the goals and expectations and determine the current status of the farm. Step 3 – it is important to identify the constraints, namely the biosecurity and management risks that exist in farms or systems. Considering the information of the previous 3 steps it is possible to propose solutions in step 4 and finally, in step 5, solutions can be implemented and results can be monitored. A high level biosecurity is a must for farms located in pig dense areas, due to high infection pressure. Therefore, a lot of research projects have been dedicated to learn about the constraints that complicate the right implementation of disease control programmes. A recent publication referring to farms in Belgium, France, Germany and Sweden documented that often external biosecurity is more important than internal biosecurity. This is probably not any different to farms in other countries and areas. Boehringer Ingelheim recently introduced 2 new tools that aim to help identify and visualize constraints related to external and internal biosecurity, pig flow, management and trace pathogen carrying agents. The ‘Pathogen Tracing Kit’, or short ‘p-Track’.With that, it will be possible to trace and monitor multiple risks associated with pathogen carrying agents in the farms: tools, farm staff, or visitors, or other fomites. Using the tool, veterinarians and farmers can measure in real time risky events related with movements . For example, when a certain object (a pushboard or an injector) is used in different areas of the farm it can be detected and quantified. more

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.

Improving plant biosecurity in Africa.

Plant biosecurity management can be a boon to agricultural economies in sub-Saharan Africa, and Australia has a wealth of expertise to share. That’s the logic behind a mentoring program that helps the Australian Centre for International Agricultural Research and the Plant Biosecurity CRC partner with fellows working at agricultural institutions in 10 African countries. The resulting program, the Australia-Africa Plant Biosecurity Partnership, aims to transfer skills in designing, delivering and managing plant biosecurity — measures to safeguard plants from pests and diseases. continue

"Biosecurity should be top priority for new Government".

"Biosecurity should be top priority for new Government". A biosecurity incursion can (and has) bring parts of the primary sector to a complete standstill; Psa did this to kiwifruit not too long ago. Today, the Ministry for Primary Industries are managing a number of incursions, including mycoplasma bovis, myrtle rust, pea weevil, and oyster parasite, to name but a few. For those facing incursions, incomes and jobs are being affected and, in many cases, their businesses cannot weather the storm; they go under. The cost of controlling and eradicating these incursions costs farmers, growers, industry, and the Government millions upon millions of dollars. Considering the critical importance of protecting New Zealand from biosecurity incursions, and being ready to quickly and effectively respond to these incursions, has to be one of the new Government’s top priorities.

Poultry biosecurity plans prepared humans for COVID-19.

Poultry biosecurity plans prepared humans for COVID-19. As state lawmakers continue to put stay-at-home orders in place, people could learn to be safe by implementing some of the steps associated with poultry biosecurity.

I can't count the number of presentations I have seen or articles I have had regarding poultry biosecurity. I am sure the same could be said for many within the livestock industry, making them a knowledgeable source to some extent. Due to the COVID-19 pandemic, there have been many recommendations floating around about how individuals should protect themselves, many of which have reminded me of steps taken on a poultry farm. Is this a time where a company could be very transparent and help consumers relate to the farm, therefore generating credibility/trust between producers and the general public? Obviously, we have all been told to stay home and minimize gatherings. Poultry farms do this daily by documenting the number of people that come in and out of the barns or enter gated areas.

How do HPAI outbreaks occur?

How do HPAI outbreaks occur? Usually with some type of contact with other birds. 

               Common biosecurity failures. 

 “People had some contact, whether wild birds and droppings, feathers or debris, or contact with backyard birds,” Rings explained. “Or it could be a lateral spread within a company where someone was not following procedures. 

Sometimes it isn’t direct, but accidental or indirect contact with birds or their products.” Then people fail to follow biosecurity procedures including the line of separation to divide the production side of a commercial poultry flock from the outside world. “It’s using dedicated farm clothing or footwear,” he continued. 

“Disposable coveralls and plastic boots are a form of dedicated clothing. It’s having inside and outside boots and using those exclusively in each location. “It can be improper house entry procedures like not doing a boot change; not using a proper foot bath, which may be dirty or empty; and not using hand sanitizer and equipment sanitation,” 

Rings said. Keeping HPAI out of a flock also includes monitoring visitors and service people, and making sure everyone follows biosecurity protocols. In the end, biosecurity is everyone’s job. “Every person has a place at the table,” he added. “But growers are the ultimate guardians of their farm. They are on duty 24/7…to prevent and block any disease coming on their farm that would devastate their flock and livelihood.”

A VISIT TO THE OKE- ARO PIG FARM.

 The scourge of African swine fever is trailed with emotional torture and financial losses. The effect of the  virus was more profound with the Covid-19 impact on the economy. The losses recorded on the farm is so high that most of the pens are empty and some farmers have diversified, looking into other agricultural ventures.

   The farm has been decontaminated severally in preparation for restocking of the pens. The biosecurity protocols have also been improved to ensure safety of the animals and the farmers. Training's  demonstrations for the farmers on biosecurity and animal health issues were conducted to keep farmers abreast of new standards in the industry.

   Farmers are encouraged to adopt stringent biosecurity protocols to ensure sustainability and profitability of the venture .

Campylobacter in poultry.

Campylobacter in poultry. Campylobacter is a leading cause of foodborne gastroenteritis in humans worldwide. Campylobacter is, in general, highly prevalent on poultry farms, but the prevalence varies by region, seasons and production types, with reported Campylobacter-positive flocks ranging from 2% to 100%. Once a broiler flock is infected with Campylobacter, the majority of birds become colonized within a few days, and the overall within-flock prevalence reaches very high levels by processing age, leading to increased carcass contamination. Campylobacter is ubiquitous in the poultry farm environment, and the sources of flock infection and risk factors influencing Campylobacter introduction are complex but horizontal transmission from environmental sources is the primary way flocks become colonized. Some of the most common factors associated with Campylobacter colonization in commercial broilers are poor farm biosecurity; the presence of other animals in the vicinity of poultry houses such as other poultry species, livestock, pets and wildlife; older processing age; large flock size; the use of ventilators; the presence of flies and rodents; and the use of old litter. Campylobacter can be introduced onto poultry farms by farm equipment, transport vehicles and farm workers. The prevalence of colonization tends to be much higher during hot weather. Campylobacter is common in the farm environment and can contaminate poultry houses via many different routes, preventing flock colonization with this organism is not an easy task, but these measures could help. Biosecurity and hygiene: Implementing strict biosecurity and good hygiene measures can help prevent Campylobacter from entering the broiler house from the outside environment. Treatment of drinking water: Acidification of drinking water with organic acids such as lactic acid, acetic acid or formic acid and water chlorination, especially when combined with other approaches, may decrease the risk of Campylobacter colonization in broilers. Litter treatment: Acidification of litter with aluminum sulfate and sodium bisulfate may decrease Campylobacter colonization frequency and cecal loads. Litter treatment with a combination of sodium bisulfate, ammonium sulfate and magnesium sulfate can significantly reduce the pH and moisture of litter as well as the numbers of contaminating Campylobacter, subsequently reducing colonization of chickens. Feed additives: A combination of 2% formic acid and 0.1% potassium sorbate in feed has been shown to be effective for preventing the colonization of broilers.

VETERINARIANS AND BIOSECURITY PROTOCOLS.

Veterinarians are often exposed to diseases that could be fatal, and this exposure has also been linked to further spread of infectious agents to other farms.The safety protocol for the vet and animals must be ensured for safety.


Bio security protocols are very important,and to this end training of vets and para-vets on these protocols are necessary.

 Diseases are emerging every time and others evolving, safety is necessary as more and more exposure cases are known and so many unreported and a lot more undiagnosed.


The health status of the vets are important just as that of the animals.Food animals ,companion animals and wildlife all poise a threat; safety is the watch word.

 Training on biosecurity protocols, use of latest disinfectants must be periodical and livestock owners should also know basic safety protocol.

Vets up-skill to prepare for future animal infectious disease emergencies in a bid to better manage future outbreaks of animal disease like avian influenza, foot-and-mouth disease and Hendra virus, veterinarians convened in Canberra for a hands-on training exercise.

 "Part of the training is to condition people to what actually happens, so it doesn't take them by surprise," he said. Dr Will Andrew"It gives them assurance of their procedure and that takes the pressure off people.

"Vets were presented with a host of disinfectant and quarantine protocols."If you go and visit a property and you don't carry out some of these procedures you run the risk, particularly as a vet, when you visit the next property of taking that disease with you," Dr Andrew said.

Facts about African Swine Fever.

The emergence of cases of African swine fever identified within the pork producing countries,shows it is important to maintain high standards of biosecurity.

The knowledge about the signs of the disease, and equally most important is to know how to curtail the spread. The pig and its close relatives, boars and hogs are the only natural host of the double-stranded, Asfarviridae family of viruses, meaning the virus does not cause harm to humans or other animals. This does not mean that humans and other animals cannot spread the virus as carriers;


 African Swine Fever (ASF) is commonly carried by arthropods, such as the soft-bodied tick, through uptake of blood from infected pigs.

 Contamination generally occurs via direct contact with tissue and bodily fluids from infected or carrier pigs, including discharges from the nose, mouth, urine and feces or infected semen.

   It also spreads through transport and consumption of contaminated pork products, and some cases have originated from failure to comply with biosecurity standards by feeding waste food to domestic pigs..

   The virus in wild boar and hogs does not manifest any signs of the disease but it remains highly contagious across all swine species and can survive in pigs for long periods of time even post-slaughter and even in frozen carcasses.  It is also important to note that curing and smoking pork products does not destroy the virus.

 The common signs are as follows: 1). High fever 40-42°C.
 2) Loss of appetite.

 3) Depression.

 4)Vomiting and/or diarrhoea
.
5) In White skinned pigs: extremities (nose, ears, tail and lower legs) become cyanotic (blue-purple color).

 6) Discrete hemorrhages appear in the skin particularly on the ears and flanks.
 7) Group will huddle together and are usually shivering.

8) Abnormal breathing.

 9) Heavy discharge from eyes and/or nose.

10) Lethargic- sometimes refusal to stand or move.

11) Very unsteady when forced to stand up.

 12) Comatose state and death within a few days.

    Pregnant sows commonly undergo miscarriage or deliver stillborn piglets that are malformed. Piglets can be tested for the virus.

Mortality rate in infected groups of pigs is high and there is no vaccination proven to prevent or cure infection.

Prevention is key,here are some steps to follow

 Ensure strict biosecurity rules. Do not take pig meat onto farms, and restrict all food (and consumption of food) to a canteen.

All staff on farm should be inducted onto a strict programme of hand and equipment sanitation before and after contact with pigs.

 - Follow rules and regulations on disposal of food waste at ferry ports and airports.

 - Provide the means for staff and visitors to thoroughly sanitize their hands and equipment.

 - Ensure that wild boar, warthogs and wild pigs, and materials potentially contaminated by such wild species do not come into contact with domestic pigs.

 - Check infected regions before importation of goods that could potentially be contaminated. - Advise and educate people on the risks of bringing back pork products from infected regions.

FARM INSPECTION POST COVID-19.

In the wake of the Covid-19 pandemic, a lot of lifestyle changes were enforces to curb the spread of the virus.
    The most important is the lock down restrictions which reduced movements within and outside states, countries and this affected farm visits.

   These restrictions is also accompanied with social distancing, wearing of masks and the washing of hands. Biosecurity protocols on farms follow these stringent rules to curb the spread of the Corona virus, now the issue of inspection on farms is a game changer.

  The Corona virus pandemic has raised the bar on biosecurity, so how will farmers engage veterinarians?

 New technologies must be employed to ensure safety of animals and farmers. Technologies designed to help farmers overcome COVID-19 restrictions may have longer-term value changing the face of farm inspections.


    This is where using phones, data, and an interactive platform will come in handy. Telecommunications is not only to ensure food security but food safety as well.

   Farm visitation, assessment and health status check of animals can be done remotely using technological innovation.  Pre- Covid-19, the use of cameras,cctv, monitors on farms was limited but post Covid-19,this will be the new norm.

   Farms can be accessed using monitors and certain sensors to check health status of animals, this will limit human and vehicular traffic. This is precision livestock farming: hands-free model to promote biosecurity.

   Read :Red Tractor innovation . Red Tractor may offer a model for others where a physical presence may no longer be possible or necessary. Standard Red Tractor assessments in the U.K. came to halt in March, but pandemic or no pandemic, the scheme needed to ensure that its members were adhering to its standards.

   It now does this through what it has termed “virtual eyes” Rather than accept an inspector on farm, members of the scheme can now be checked via one of two ways.

 One option requires members to submit documentation for pre-assessment which is then followed by a partial assessment using live-streaming technologies to produce a real-time farm inspection.

Alternatively, the entire assessment – reviewing paperwork and a visual inspection – can be streamed live with an assessor.

Vaccines and biosecurity to replace antibiotics in pig industry.

The increase use of vaccines and better sanitation and biosecurity are the 2 most common changes US pig, cattle and poultry producers are making in response to the loss of shared use antibiotics.That was a key finding of a new study just completed by animal health and nutrition consulting company Brakke Consulting, headquartered in Dallas, TX. 

 The survey, New Strategies for Health and Performance in US Livestock and Poultry Production, was conducted among beef, dairy, swine and poultry producers in late 2016. Since January 1, 2017, new antibiotic regulations as well as the Veterinary Feed Directive have been effective in the United States. 

 In a press release, the consulting firm wrote, “Although there was some variation among species groups, vaccination protocols and improved sanitation were the top 2 strategies for 70% or more of all producers. Other strategies included reduced co-mingling of animals/birds, changes in feed additives, changes in facilities, use of immune modulators and changes in genetics.” 

 The study was conducted late in 2016; half of producers said they had already made changes to their operations. About 75% indicated that they were ready for the changes, of which the poultry sector was the most prepared source

Bird flu sensitization seminar and new compensation scheme.

The bird flu virus ravaging many nations is a wake up call for strict biosecurity protocols and surveillance strategies. Poultry keeping is a money spinner and a source of employment, and raw materials for many companies,but a breech in bio security measures will make a mess of the business and loss of products. In line with the go back to agriculture initiative, all hands must be on deck to support farmers,agribusiness' and feed millers to ensure there ventures are profitable to provide wholesome products for the people thus contributing to food security. The Lagos state avian influenza office is organizing a sensitization seminar on bird-flu and how to stop the virus. The scope of seminar will be ; 1) Biosecurity. 2) New compensation scheme . The seminar will hold at Johnson Agiri Complex,Oko Oba Agege on the 15/2/2017 @ 9am prompt. This is an open invite for farmers ,live-poultry-dealers,veterinarians,feed-millers and other members of the poultry value chain. Products will be on display, for your education and purchase.

Early approach to managing new castle disease.Newcastle disease affects chickens and other captive and wild birds.Humans are not normally affected,

Humans are not normally affected, but cases of people in direct contact with infected birds that developed a very short-term eye infection, which passes without treatment has been reported.

 The disease is spread by direct contact with body fluids of infected birds, especially their feces,it can also spread indirectly through people and objects that have been in contact with infected birds, or their excretions (such as feces).

 The most common objects that can carry the disease are 1)vehicles. 2)equipment 3)clothing/work overalls 4)water and feed troughs.The disease can also spread from wild birds to domesticated birds.

Spread of diseases in farmed animals shown using social media analysis.

The Spread of diseases in farmed animals can be shown using social network analysis according to a research published in the PLOS. 

Researchers have shown that looking at movements of operators and vehicles between farms in the same way we look at contacts in social networks can help explain the spread of dangerous infectious diseases of livestock, such as foot-and-mouth disease and avian influenza. This research can contribute to the development of more accurate tools for predicting the spread of livestock diseases and may help implement more effective biosecurity measures in farms.

This research, published in PLOS Computational Biology, can contribute to the development of more accurate tools for predicting the spread of livestock diseases and may help implement more effective biosecurity measures in farms. The research showed that the network of contacts originated from on-farm visits by veterinarians in dairy farms of Northern Italy displays hidden features that cannot be detected by simply looking at the frequency of visits and unveils patterns of infection otherwise unexplained. 

The authors discovered that veterinarians' movements produce an unexpectedly large number of potentially infectious contacts between farms that can quickly spread dangerous livestock diseases. The research, made possible by the availability of high-resolution data in space and time on veterinarian movements in the study area, shed light on the actual significance of operator movements in disease spread, a still poorly understood topic due to the highly diverse and complex nature of such movements and to privacy issues in data collection. 

 The researchers compared the role of veterinarian movements on diseases spread with those of animal exchange between farms, which is recognized as the most effective transmission route for livestock infectious diseases. 

 They found that co-occurrence of operator movements and animal exchanges is synergistic, largely amplifying the potential for disease propagation. The study shows how multilayer network analysis substantially improves the way diseases spread can be described, thus contributing to their control.
