Biosecurity Measures

The threat posed by avian influenza (AI) in the UK remains dynamically evolving. As wildlife rehabilitators and veterinary professionals, our role in identifying, advising and preventing transmission is critical. Avian influenza remains a major concern for everyone working with birds from wildlife rehabilitators to veterinary professionals. With cases continuing across the UK, early recognition and rigorous biosecurity are key to protecting both wild and captive populations. Many wild birds, especially waterfowl and gulls, may carry avian influenza without obvious signs, but symptomatic cases can present with: *Lethargy or reluctance to fly *Head tilt, tremors, incoordination or recumbency *Respiratory signs such as sneezing, gurgling or open-mouth breathing *Swollen head, eyelids or neck *Sudden, unexplained death, especially in groups **During high-risk periods, it’s recommended to temporarily limit admissions of the most affected taxa (e.g. swans, ducks, gulls, birds of prey that feed on carrion) and apply quarantine for up to 14 days to all avian admissions where feasible** Biosecurity: Avian influenza spreads via contaminated faeces, feathers, body fluids, water, feed, footwear and equipment, and only a few viral particles can cause infection. Every centre should maintain written biosecurity protocols and contingency plans. Good practice includes: * Quarantining all new avian admissions before they enter the main centre. *Maintaining clear epidemiological units (EUs) within your site to reduce cross-contamination. *Using DEFRA-approved disinfectants (such as Virkon S) at the correct dilution (for AI) for all cleaning, footbaths and vehicle disinfection. Organic matter must be removed first, and disinfectant refreshed when visibly contaminated. *Keeping dedicated PPE and footwear for each enclosure or EU, and using FFP3 masks, gloves, coveralls and eye protection for all wild birds. *Minimising staff and equipment movement between units, and documenting movements daily. *Storing feed and bedding securely away from wild birds and rodents. *Covering aviaries and food/water areas to prevent faecal contamination. Even small lapses, like reusing boots or equipment between pens, can carry infection to other species, including vulnerable mammals such as foxes or mustelids. Failure to spot symptoms or enforce biosecurity can lead to: *Rapid HPAI spread within a centre or practice *Mandatory culling and prolonged site closure (often many months) *Zoonotic exposure and welfare risks to staff and animals *Significant reputational and financial consequences Please: 1)Review your admission and isolation protocols. 2)Audit staff movement, PPE use and disinfectant routines. 3)Refresh training across your team, volunteers and students. 4)Keep up to date with APHA/DEFRA outbreak assessments and prevention zone rules.

Between-Flock Cleaning: The Hidden Key to Poultry Biosecurity A successful poultry production cycle starts long before the next flock arrives. Between-flock cleaning is more than housekeeping—it's one of the most effective biosecurity measures to reduce disease pressure, improve flock health, and protect performance. Every step matters: ✅ Remove birds and litter completely ✅ Dry clean to eliminate dust and organic matter ✅ Wash and degrease all equipment and surfaces ✅ Allow the house to dry thoroughly ✅ Disinfect correctly with the right concentration and contact time ✅ Verify effectiveness before restocking One of the biggest challenges is what you can't see. Biofilms inside water lines, dust on fan blades, feed-line residues, and cracks in brood areas can all harbor harmful pathogens if they are overlooked. Remember: Disinfection only works on clean surfaces. Skipping one step reduces the effectiveness of the next. Consistent cleaning protocols today lead to healthier flocks, better productivity, and lower disease risk tomorrow. #Poultry #Biosecurity #PoultryFarming #BroilerProduction #FarmManagement #AnimalHealth #FoodSafety #Agriculture #Livestock #DiseasePrevention #Salmonella #EColi #PoultryHealth #FarmBiosecurity #BestPractices

 Where Engineering Meets Biosecurity: Designing a hatchery is not just about walls and machines , it’s about creating a controlled ecosystem that protects the embryo from the moment the egg enters until the chick leaves. 1️⃣ Biosecurity by Design A hatchery should be built with strict “clean-to-dirty” workflow. Movement of people, eggs, and equipment must follow a one-way path to prevent cross-contamination. Foot dips, hand sanitizers, pest control, and restricted access zones are non-negotiable. Every unnecessary step by staff increases contamination risk. 2️⃣ Ventilation & Air Units Airflow isn’t just about comfort , it’s about oxygen supply, CO₂ removal, and controlling airborne pathogens. Air handling units must supply pre-conditioned, filtered air with controlled temperature (24–27 °C) and humidity. Positive air pressure in clean areas and negative pressure in dirty areas keeps contaminants out of sensitive zones. 3️⃣ Humidity & Moisture Loss Control Incorrect humidity impacts hatchability, chick size, and welfare. The target is controlled egg moisture loss during incubation (e.g., ~11–12% at 18.5 days for most flocks). Too much loss = dehydrated chicks. Too little = sticky chicks with poor navels. This means precise control of ventilation, damper settings, and incoming air conditions. 4️⃣ Staff Movement = Pathogen Movement Every movement is a potential biosecurity breach. Staff should be assigned to specific zones, with no cross-over between egg handling, incubation, hatching, and chick holding areas. Changing rooms, showers, and dedicated PPE per zone are essential. 5️⃣ Pressure Control = Contamination Control Think of air pressure as an invisible barrier. Positive pressure flows from clean to less clean areas, pushing potential contaminants away from critical zones like egg storage and incubation. Negative pressure is used in waste and cull rooms to trap contaminants inside. Airflow maps and pressure monitors are essential tools for hatchery managers. 👌 A high-performing hatchery isn’t just well-equipped , it’s engineered for biosecurity first. Every wall, door, and air duct is part of the disease prevention strategy.

Biosecurity in Aquaculture: More Than Disease Prevention Biosecurity in fish farms is often reduced to “avoiding disease,” but in reality, it is a comprehensive risk-management framework. It starts long before fish enter the ponds. Biosecurity includes: • Zoning and farm layout: separating clean and high-risk areas, controlling internal movement • Water management: filtration, disinfection, and monitoring of inlet and outlet water • Seed and fry sourcing: health certification, quarantine, and acclimation protocols • Equipment control: dedicated tools per unit, proper cleaning and disinfection routines • People management: visitor logs, restricted access, footwear and clothing control • Monitoring & records: daily observations, mortality logs, and early warning indicators The weakest point in any biosecurity system is not the technology— it is inconsistency. Skipping one step, even once, can compromise months of good management. Strong biosecurity reduces: • Disease outbreaks • Antibiotic and chemical use • Production variability • Economic losses And most importantly, it increases predictability, which is the foundation of sustainable aquaculture. Biosecurity is not about fear of disease. It is about control. Question for professionals: Which biosecurity gap do you encounter most often in fish farms—people, water, seed, or management discipline?

Microsoft Research find, and help fix, a hidden biosecurity threat. Proteins serve as the engines and building blocks of biology, influencing how organisms adapt, think, and function. With the aid of AI, scientists can now design new protein structures from amino acid sequences, paving the way for innovative therapies and cures. However, this capability comes with significant responsibility, as many tools are open source and may be vulnerable to misuse. To assess the risks, Microsoft scientists demonstrated how open-source AI protein design (AIPD) tools could be utilized to create thousands of synthetic versions of a specific toxin. By altering the amino acid sequence while maintaining its structure and potential function, the experiment revealed that many redesigned toxins could evade the screening systems employed by DNA synthesis companies. This finding highlighted a critical blind spot in biosecurity, prompting the establishment of a collaborative, cross-sector initiative aimed at enhancing the resilience of DNA screening systems against AI advancements. Over a span of 10 months, the team worked discreetly and efficiently to mitigate the risk, developing and implementing new biosecurity “red-teaming” processes. Their efforts culminated in a “patch” that has been distributed globally to DNA synthesis companies.

Rethinking PepMV Strategy: Taming an Endemic Threat in a New Era of Viruses For years, Pepino mosaic virus (PepMV) has been a persistent, costly battle for tomato growers. As an endemic pathogen, its ability to downgrade up to 38% of premium fruit due to severe quality defects makes it a significant economic threat. The virus is a master of mechanical transmission, spreading silently and rapidly on tools, hands, and clothing. But the challenge of managing PepMV has evolved. The emergence of Tomato brown rugose fruit virus (ToBRFV) has added a dangerous new dimension to this old fight. While ToBRFV is a major threat on its own, its interaction with PepMV creates a synergistic effect that growers cannot ignore. Research confirms that co-infection can dramatically increase the viral load of PepMV within the plant. This means that even a typically mild, low-symptom PepMV infection can become highly damaging when ToBRFV is also present, leading to unexpected and severe losses. While we must adapt to the risk of co-infection, it is crucial not to lose focus on the fundamentals of managing PepMV itself—the primary subject of this comprehensive review. The aggressive Chilean 2 (CH2) strain remains dominant globally, and contaminated seed lots are still a primary pathway for introducing the virus into clean facilities. An effective, modern management strategy must be robust enough to handle PepMV on its own, yet sophisticated enough to account for the risk of co-infection. Our technical guide outlines four non-negotiable pillars: Uncompromising Biosecurity: This is the absolute foundation. Strict, auditable disinfection protocols for all tools, surfaces, and personnel are your first and best line of defense against mechanically transmitted viruses like PepMV. Mandate Clean Starting Material: You must start clean to stay clean. Using certified, high-sensitivity tested (RT-qPCR) seed and transplants is the most critical control point to prevent the introduction of PepMV. Strategic Cross-Protection: In regions where PepMV is endemic, proactive "vaccination" with regulated, mild strains is a proven strategy. It protects the crop from aggressive wild-type PepMV infections, stabilizing your yield of Class I fruit. Expanded Surveillance: Your diagnostic plan must evolve. Routine testing should now be designed to screen for both PepMV and ToBRFV to give you a complete picture of your crop's health and help you anticipate potential synergistic threats. Effectively managing PepMV today means mastering the fundamentals while adapting to new, complex viral interactions. How has the risk of co-infection changed your approach to biosecurity and diagnostics?
