Consumers face potential increases in egg and dairy prices due to culled flocks and infected herds. Food supply chain disruptions possible. Increased healthcare costs if human transmission accelerates. Pet owners face disease risks to companion animals.
Likely expansion of USDA surveillance and quarantine protocols. Potential emergency declarations for affected agricultural regions. Increased funding for vaccine development and pandemic preparedness. Possible trade restrictions on poultry/dairy exports. Enhanced worker safety regulations in agricultural facilities. Public health communication campaigns regarding food safety.
