USDA Announces H5N1 Virus Particles Found in 1 of 96 Cull Cows Tested
USDA Food Safety Inspection Service announced last Friday that PCR tests on cull dairy cows sent to slaughter returned one positive test for H5N1 in muscle tissue. 96 cull cows were diverted from the food supply chain when USDA meat inspectors noticed the animals showed signs of illness at the facility (USDA veterinarians and inspectors are tasked with monitoring the welfare of animals at slaughter facilities and removing sick animals from the slaughter pens). Those 96 cull cows were then tested for the H5N1 virus during necropsy. Muscle tissue samples from 1 of the 96 cows did test positive using a PCR test which does not discern whether the virus was live virus at the time of slaughter or if the animal had been previously exposed to H5N1. None of the meat from the 96 cull cows in this scenario entered the food supply chain. The process by which USDA personnel identified the animals is also part of the routine procedure at slaughter facilities, and the agency states that this is further proof the food supply is safe. Prior studies by USDA have shown that cooking beef to 145 degrees (medium) is effective in killing the virus.

Bulk Tank Sampling for H5N1 Could Be Coming
Reuters has a scoop out today (link in the headlines above) detailing how USDA is closing in on authorizing bulk tank samples to replace the individual cow testing requirement for interstate movement. We are awaiting more details from USDA at this time.
Free PPE Available Through the Georgia Department of Agriculture
While the symptoms are mild, dairy farmers are encouraged to limit exposure of their employees as much as possible by incorporating the use of personal protective equipment into the milking parlor. This can include gloves, aprons or coveralls, rubber boots and boot covers, and some form of eyeware or face covering. It is also important to not touch your eyes, nose, or mouth with uncleaned hands or gloves when working with animals (this is a good rule of thumb generally).
The Georgia Department of Agriculture has PPE available to farms at no cost. Contact your dairy inspector for more information.
