Meat inspection and food safety concerns: open data kit (ODK)that Uganda is using to improve livestock disease surveillance and reporting.

 

Open Data Kit to improve livestock disease surveillance and reporting in Uganda.Surveillance of livestock diseases is key to reduce their harm to livelihoods, development and even humans. Meat inspectors in Uganda are using the Open Data kit (ODK) tool to improve animal disease surveillance and reporting, and sharing their experiences and knowledge with peers. The tool was rolled out at a training workshop held in October 2021 at the Makerere University College of Veterinary Medicine, Animal Resources and Biosecurity (COVAB). 

 The workshop aimed to boost, retool and equip inspectors in routine meat inspection procedures, hands-on skills in meat hygiene and food safety procedures, and knowledge of meat inspection regulations and standards.

 How ODK works .

ODK is an open-source mobile data collection platform that enables users to fill out forms offline and send data to a server when a connection is found. 

 why reforms are necessary.

Once on the server, the data can be viewed, downloaded and acted upon. In the first six weeks following the training, the meat inspectors had uploaded more than 300 reports to the ILRI server.

 Collected data can be used to determine prevalence of diseases, locations and age-group of animals affected, and inform response. 

 Speaking at the review meeting, Annie Cook, a senior scientist at ILRI, commended the inspectors for their interest in improving the reporting of data on disease surveillance at the points of slaughter, saying: 'As pioneers at using the ODK tool in the meat inspection sector, your feedback and input is important in refining the tool so that it is useful and can be used in the future.' 

 Reporting their experiences, the meat inspectors noted that the tool was user-friendly and most did not have major challenges in uploading data. 

 

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.”

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.

The rise of Avian Influenza.

 

So far, 2022 has been a deadly year for the world’s birds. Avian influenza continues to rise, and this is hot on the heels of two years that the U.S. CDC says saw more outbreaks than the previous four years combined. Each outbreak of avian influenza can have huge ramifications for animal and human welfare. And, of course, a devastating impact on the economy and global food security. 

Just a single outbreak in the Netherlands in 2003 cost an estimated 150 million euros and the culling of some 30 million birds. Right now, other countries – like the UK – are facing similar losses. A look at the current spread of avian influenza and the evolving discussion on vaccination. 

  Biosecurity and hygiene is currently the first line of defense against avian influenza in most countries. While this can limit exposure, this is not fool proof as outbreaks grow in size and scope each year. The U.S. CDC has reported that globally “there were more outbreaks reported in 2020-2021 than in the previous four years combined.” What’s more, viruses are cropping up in countries that have been clear of avian influenza for many years – like Canada. 

The CDC reports that, in December 2021, HPAI A (H5N1) viruses were detected in birds in Newfoundland. This is the first identification of this virus in the Americas since June 2015. Vaccines have been considered as a potential control measure against avian influenza, but these are often not widely available or used in many markets. There has been some recent discussion about re-evaluating vaccination though. 

 According to Julien Denormandie the French agriculture minister,There is “no other solution in the long term than to have vaccination.”  Vaccines are often not used due to concerns about trade disruptions. 

In the past, export bans have been enforced on countries with vaccination policies. This is due to concerns such as not being able to differentiate vaccinated animals from infected animals, which occurs if a vaccine is not a 'DIVA vaccine'. DIVA vaccines and diagnostics :DIVA stands for Differentiating Infected from Vaccinated Animals. For Avian influenza, this can be achieved by using a vaccine based on a different strain (e.g. H5N2) than the current field strain (e.g. H5N1) and using a serological test that can differentiate between vaccine-induced antibodies (e.g. against N2) and antibodies against the field virus (N1).

  Current thoughts on whether there may be scope for vaccination in the future:

 The loss of millions of birds is a significant welfare issue that requires considering all avenues of prevention. 

 The Poultry Veterinary Study Group of the EU published a paper in October calling for an ‘open-minded evaluation’ of vaccines, saying it would ‘offer better protection to poultry'. 

 The French minister of agriculture sees vaccination as a long-term, viable solution in the face of rising losses. Though it may be too late to mitigate the impact of the current outbreaks, vaccination could become a future prevention measure alongside alongside biosecurity and other tools. 

 The info graphic below shows the impact of Avian Influenza in 2021.

Avian Influenza: Effective Biosecurity is Critical to Prevention.

 

Avian Influenza: Effective Biosecurity is Critical to Prevention.Avian influenza (AI) is a very important infectious disease of both poultry and other birds caused by influenza type A viruses. Although multiple viral strains exist, the disease appears in two forms, highly pathogenic avian influenza (HPAI) and low pathogenic avian influenza (LPAI). 

 The distinction between pathogenicity of a particular avian influenza virus is based upon its potential to result in severe disease in poultry and the presence of specific genetic attributes that contribute to this virulence. 

 In both poultry and wild birds, LPAI may present either sub clinically or as mild respiratory disease. This form of the disease in poultry might be observed as sneezing, coughing, and nasal or ocular discharge with a negative impact on productivity despite mortality remaining low. 

 As a natural reservoir for avian influenza, wild birds in many cases may not exhibit any clinical signs, even in the event of HPAI infection. Poultry may experience mortality rates approaching 100% during a HPAI outbreak and exhibit clinical signs such as lethargy, severe respiratory distress leading to cyanosis, edema and hemorrhage in tissues of the head, legs, internal organs, muscles, neurologic deficits, and diarrhea.

 Avian influenza viruses have a predilection for the intestinal and respiratory tracts of the bird, therefore oropharyngeal and cloacal swabs are common diagnostic samples submitted to detect this pathogen.Get the guide.

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

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 .

Covid-19: How inspectors in abattoirs caused an outbreak.

Last month, two abattoirs in south-west Victoria were visited by inspectors who later tested positive for COVID-19 and were contagious while on site, but only one of the cases led to a large outbreak.


There have been criticisms leveled over how the state's Department of Health and Human Services (DHHS) handled both cases, but experts say there are lessons to be learnt in understanding what happened.

 The largest meat producer in the state, Warrnambool's Midfields Meats, has been on high alert as clusters in other abattoirs continue to grow

.When general manager Dean McKenna found out that a meat inspector who had visited the site had tested positive, the company immediately shut the plant down — before it had heard from the health department.

 The company organised testing for nearly 1,000 workers via the local health service, but before the results were known DHHS advised that the meatworks could reopen.Mr McKenna said he ignored that advice and opted to keep the abattoir shut."We still wouldn't go back to work until we had a feel for where the testing was going," he said.


 The company made the inspector wear full personal protective equipment, a measure that is now being made mandatory across all Victorian abattoirs.

 For the Australian Lamb Company (ALC), based in the small town of Colac, it's been a different story.
A meat inspector there tested positive for COVID-19 in the same week.There are now more than 80 cases associated with the cluster, which has also spread into the community along with 11 more infections suspected to have been transmitted through the community.

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.

Meat processing facilities take action to protect workers.

Meat processing facilities take actions to protect workers. The Covid-19 pandemic is affecting all sectors of the economy but the greatest impact is in the meat /poultry processing sector.

In the wake of the Corona virus pandemic a lot of workers in abattoirs and meat processing plants had the virus which led to closure of such plants.

 A lot of biosecurity protocols was adopted in all abattoirs and meat markets to stem the spread of the virus. In Nigeria,the use of masks is compulsory, hand washing before you enter the abattoir  is also compulsory and physical distancing .

The government also  ensured supervised slaughtering such that operations in abattoirs was on elected days. see

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.

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.

FOOD SAFETY FROM FARM TO FORK.

Governments must play active role in food safety. Governments have an important role to play in food safety to ensure it gets the attention and investment it deserves, according to a senior food standards officer with the Codex Alimentarius secretariat.. This means that a government needs to have a strong food control system. For many countries this is still a challenge, they are still working toward having the appropriate infrastructure not only to establish regulations for food but to implement them and help food producers to know what they are supposed to do. They can also play a role in bringing together the different players and sectors along the food chain and making sure everyone is aware of the importance of food safety,” Cahill said. WHO Director-General Tedros Adhanom Ghebreyesus, said every year unsafe food is responsible for thousands of deaths, which are all preventable. “This year’s World Food Safety Day is a reminder that we can all play a role in making food safer. From the time food is grown and transported to when people are shopping and preparing meals each of these is a chance to prioritize food safety. “Food production is a chain of events, it starts even before the farm as some of the inputs such as animal feed also contribute to the safety of food. We have to look at what happens at the farm, what happens after that in terms of harvesting, what happens then in terms of processing and transformation of the crops or animal products and then the transportation and retail sectors. At all of those points there is an opportunity for our food to be contaminated and become unsafe. Producers must keep hazards or contaminants out of food or make sure they stay at as low a level as possible, said Cahill. “So whether you are growing crops or rearing animals, good hygiene and biosecurity are important, good husbandry and veterinary practices and also good environmental waste management so you are producing food in an environment which minimizes the possibility for that food to be contaminated,” she said Adopted from food safety news.

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.

DISEASE TRANSMISSION AND BIOSECURITY PROTOCOLS.

BIOSECURITY.  Following simple but specific protocols everyday to positively influence animal health, food safety and public health.

 What are the basic protocols in biosecurity? READ

 Biosecurity basically entails, prevention of pathogens from entering premises to ensure there is no disease incidence, and curtail spread of diseases in cases of outbreaks.

  Pathogens are disease causing microorganisms that usually have devastating effect on animals, resulting in decreased production and death in severe cases.  Pathogens can be bacteria, viruses, fungi and prion.

.  The animal kingdom is riddled with several pathogens that wreck havoc on these animals irrespective of specie.  These pathogens are also of importance to man, especially when these cause zoonotic diseases.

 Zoonotic diseases are spread from animals to man, and sometimes there is a reverse zoonoses where man actually spreads the disease to their animals.

  Route of transmission.  The basic routes are:  Direct contact.  Aerosol.  Oral.  Formites.  Vector borne  Zoonoses.  Reproduction.  Environmental contamination.

  Mode of transmission.  Direct contact ;disease spread by contact with open wounds, mucous membrane of an infected animal or its secretions/tissue fluids.

Disease can also spread through contact with reproductive fluid(blood, urine and saliva) during breeding, or from mother to offspring.

  Aerosol; droplets containing the pathogenic agent travel in air and are inhaled as respiratory droplets by animals

 Oral; ingestion of the pathogenic agent from contaminated feed ,chewing/licking contaminated objects in environment and water.

 Formites; spread of the pathogen through contact with inanimate objects contaminated by infected animals.

Man can act as formites by transferring these pathogens in through soiled boots, gloves or tools.

Avian influenza viruses can persist in footbaths and manure.

Avian influenza viruses can persist in footbaths and manure.Growers shouldn’t assume the disinfectants they use in footbaths are effective against avian influenza (AI), indicates a study from the University of California–Davis. Researchers conducted a survey about biosecurity practices in California and then used the information to design experiments to test the effectiveness of footbath disinfectants against AI. They also evaluated the longevity of AI viruses under different conditions. “Surprisingly,” they say, quaternary ammonia and quaternary ammonia plus glutaraldehyde-based footbaths did not eliminate highly pathogenic H5N8 or low-pathogenic H6N2 particles on boots. However, a chlorine-based granulated disinfectant was able to destroy the virus, say Rüdiger Hauck* and colleagues. To evaluate the longevity of AI viruses in litter and feces, they seeded different bedding samples from commercial layer, broiler and turkey production units with the same two AI viruses. Live H5N8 particles in layer feces remained for at least 96 hours, compared to less than 60 hours in broiler and turkey bedding. However, H6N2 low-pathogenic viruses persisted less than 24 hours in all the different substrates. This knowledge may help producers determine effective litter treatments to destroy AI viruses in the bedding material.
