While highly pathogenic avian influenza (HPAI) has primarily affected poultry, there is a growing concern about its potential impact on pigs. Although only one natural case has been reported in a feral hog in the United States, the risk of transmission from waterfowl to pigs cannot be ignored.
Waterfowl serve as the primary reservoir for H5N1, posing a threat to poultry operations. However, hog farmers can significantly reduce the risk of infection by implementing robust biosecurity measures.
These measures include vaccination, ventilation control, personal protective equipment, and restricting access to swine barns.
Pigs and humans can act as mixing vessels for influenza, potentially leading to the emergence of new strains. This is why it's crucial for hog farmers to maintain strong biosecurity practices to protect their herds from various diseases, including African swine fever.
The USDA regularly conducts surveillance to detect influenza viruses and develop specific vaccines if needed.
The National Pork Board is also working on a unified response plan to address the potential threat of H5N1 in pigs.
Having a Secure Pork Supply Plan, which MU Extension can assist with, is essential for evaluating and improving biosecurity protocols.
This plan can be a valuable tool in helping farmers identify and address potential vulnerabilities in their operations.
By prioritizing biosecurity, staying informed about the latest developments, and having a well-prepared response plan, hog farmers can help protect their herds from H5N1 and other diseases.
