Report

The U.S. Food and Drug Administration (FDA) has launched a nationwide program to sample and test raw cow’s milk cheese for Highly Pathogenic Avian Influenza (HPAI) H5N1. This initiative aims to detect the virus in cheese products and take necessary follow-up actions to protect consumers and prevent the spread of contamination.

Focus on Raw Milk Cheese

The FDA is targeting raw milk cheese in this testing program due to its use of unpasteurized milk. While pasteurized milk is considered safe, as pasteurization effectively neutralizes HPAI H5N1, the FDA advises consumers to avoid raw dairy products. The agency has emphasized that unpasteurized products could carry risks of contamination.

Nationwide Sampling and PCR Testing

As part of the program, the FDA will collect samples from warehouses and distribution centres nationwide. These samples will undergo polymerase chain reaction (PCR) testing to detect the presence of HPAI H5N1. If any sample tests positive, it will undergo further viability testing using an egg inoculation technique developed by the U.S. Department of Agriculture (USDA).

Follow-Up Measures for Contaminated Products

The FDA plans to complete this task by March 2025. After testing is concluded, the agency will release the results. If the testing identifies viable virus strains, the FDA will take specific follow-up measures, tailored to each situation, to safeguard public health and manage any contaminated products.
