What is HPAI and why is it an issue?

Highly Pathogenic Avian Influenza (HPAI) is a illness that’s extremely contagious and infrequently lethal in poultry, attributable to extremely pathogenic avian influenza A (H5) and A (H7) viruses; it’s also often known as hen or avian flu. HPAI viruses will be transmitted by wild birds to home poultry and different hen and animal species. Although hen flu viruses don’t usually infect people, sporadic human infections have occurred. It is vital to notice that “highly pathogenic” refers to extreme impression in birds, not essentially in people.

In April 2024, the U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA-APHIS) confirmed the detection of HPAI in business desk egg layer flocks in Michigan and Texas. 

Are eggs within the retail market suitable for eating?

Yes. The probability that eggs from contaminated poultry are discovered within the retail market is low and correct storage and preparation additional cut back the chance. In 2010, the U.S. Food and Drug Administration (FDA) participated in a joint danger evaluation with the USDA Food Safety and Inspection Service (FSIS) to look at the human well being impression of HPAI in poultry, shell eggs, and egg merchandise. The risk assessment decided that the chance of people turning into contaminated with HPAI by the consumption of contaminated shell eggs is low. For occasion, when a case of HPAI is detected within the US, the possibility of contaminated poultry or eggs getting into the meals chain is low due to the fast onset of signs in poultry in addition to the safeguards in place, which embrace testing of flocks and federal inspection packages.

Additionally, when meals is correctly ready and saved, the chance of customers turning into contaminated with HPAI is decreased even additional. For extra info of HPAI and human well being go to the Centers for Disease Control and Prevention (CDC) website.

Do I have to make adjustments to my meals preparation? 

There isn’t any proof that the virus will be transmitted to people by correctly ready meals. Safe meals dealing with and preparation is at all times vital. Cooking poultry, eggs, and different animal merchandise to the right temperature and stopping cross-contamination between uncooked and cooked meals are the keys to forestall any meals security hazard. To this finish, the FDA’s Food Code gives pointers on correct preparation of meals to retail institutions; furthermore, the FDA has printed a number of reality sheets, pamphlets, flyers, and movies on correct preparation of meals for each customers and retail meals institutions.

What federal companies are accountable for guaranteeing the security of eggs?

The FDA and USDA-FSIS share regulatory authority over egg security. In addition, the USDA-APHIS conducts a management program that certifies poultry breeding inventory and hatcheries as Salmonella Enteritidis (SE) – free and the USDA’s Agricultural Marketing Service (AMS) conducts a surveillance program to make sure correct disposition of restricted shell eggs (i.e., eggs that can not be marketed as desk eggs).

Under the Federal Food, Drug, and Cosmetic Act, (FFDCA) the FDA protects customers towards impure, unsafe, and fraudulently labeled meals, which incorporates shell eggs. The FDA has laws in place that govern correct manufacturing, transportation, and storage of shell eggs. 

The USDA has major duty for implementing the Egg Products Inspection Act (EPIA). Under the EPIA, FSIS has major duty for the inspection of processed egg merchandise to forestall the distribution of adulterated or misbranded liquid, frozen and dried egg merchandise.

Is the FDA taking steps to forestall the unfold of HPAI on farm visits throughout egg inspections?

Following the 2014-2015 avian flu outbreak, the FDA up to date its biosecurity protocols for on-farm visits to forestall the unfold of HPAI throughout egg farm inspections. Before initiating an egg farm inspection, the FDA:

• Uses a HPAI risk-based classification system to find out the order during which egg farms are inspected, 
• Contacts the State Veterinarian/State Animal Health Official earlier than initiating inspections to make sure there are not any quarantines or different causes investigators mustn’t go to a selected farm,  
• Conducts a examine of probably the most up-to-date info on USDA’s HPAI reporting web site for any detection in shut proximity to the meant inspection,
• Follows the necessary ready durations between inspections and makes use of a number of inspection groups,
• Thoroughly washes the automobiles used throughout inspection earlier than and after each inspection and on the finish of day by day on multiday inspections. This is adopted by sanitation of the ground mats, the wheel wells and undercarriage of the car with applicable disinfectants.

When outbreaks like this happen, the FDA evaluates its different inspection packages which will comprise an on-farm part and considers changes to these packages.  We do retain the power to answer emergencies or different occasions as mandatory, nonetheless, whereas following applicable biosecurity practices.

Should farmers who’ve biosecurity plans in place be involved about HPAI?

Farmers who constantly comply with the biosecurity necessities in 21 CFR 118.4(b) will cut back the potential danger of HPAI an infection in birds on the farm. The biosecurity necessities of this regulation, that are aimed toward stopping the introduction or switch of Salmonella Enteritidis onto a farm, additionally serve to scale back the chance of HPAI contaminating the farm. Since wild birds and migratory waterfowl will be carriers of HPAI, the requirement to forestall wild birds, cats, stray poultry, and different animals from getting into poultry homes additionally serves to guard towards HPAI.

Are there further biosecurity measures farmers can implement to additional defend their farms from HPAI?

The USDA’s APHIS works to defend America’s animal and plant sources from agricultural pests and illnesses. APHIS has developed biosecurity measures for poultry that are available at their web site: Defend the Flock – Biosecurity 101.
