In the United States, poultry vaccination is likely to focus primarily on egg-laying hens, a strategy that contrasts with the facilities designated for broiler chickens, which are primarily raised for meat consumption. During the current outbreak, more than 77 percent of the domestic poultry affected have been commercial egg-laying hens. According to a USDA press release, the agency is considering a “targeted and thoughtful strategy” for vaccination. However, the broiler chicken industry raises concerns, fearing that even targeted vaccination of laying chicken hens could have undesired consequences. National Chicken Council’s senior vice president, Ashley Peterson, states that other countries appear to be considering the unnecessary ban of all U.S. poultry products, even as the U.S. only prioritizes vaccinating laying hens. Peterson explains, “We would prefer not to cope with the virus. We would prefer to eliminate it completely.” The organization supports USDA’s current policy, which involves culling infected flocks and increasing biosecurity measures on farms. However, Carol Cardona, a professor at the University of Minnesota’s College of Veterinary Medicine, questions whether biosecurity alone can effectively eliminate the disease. “Farmers are so fatigued from the emphasis on biosecurity due to extensive prior experience with the virus that it’s difficult to pinpoint where the infection is coming from,” she points out. Cardona highlights that the disease can be transmitted to chickens through activities, vehicles, and equipment, not just the animal itself. In the face of the widespread disease, she notes that discouraging the use of farms as bad experiments and urging continued verification of infection sources is crucial. “Farmers are so fatigued from the stress of monitoring the situation that they are so preoccupied with the medical literature,” she explains. Without more information on how the chickens are being infected, it is challenging to implement targeted biosecurity measures. Despite these challenges, the U.S. is working concertedly with trade partners to minimize the impact of vaccine deployment on export markets, amounting to “short-term trade disruption” by regulating, restricting, or altering the date of vaccine deployment. Lorenzoni emphasizes that while vaccination inherently reduces viral load, it does not effectively prevent the disease from spreading. In a bid to minimize transmission, Lorenzoni Advises that vaccinated hens should move as quickly as possible through trade by undergoing window checks to detect and report cases quickly. Theבית winners of the virus are seeking alternatives to traditional “insecticide,” while experts confront the pressing question of why the disease is resurfacing in so many areas, including the U.S. With trade disruption.colorning issues, U.S. exposure to foreign markets may be prolonged. All of this is part of a larger conversation among the U.S. and全球 communities about the dynamics of public health responses, disease spread, and global trade.
