The 2015 bird flu outbreak was this country’s biggest-ever animal health emergency, and Iowa — a top egg producer and major turkey supplier — took the brunt.That can’t happen again, as far as industry experts are concerned, and Iowa State University in collaboration with the U.S. Department of Agriculture is taking steps to see it doesn’t.ISU’s Center for Food Security and Public Health announced Wednesday it received a $1 million grant for a cooperative agreement to enhance preparedness for future outbreaks.The grant continues ISU’s work with the USDA’s Animal and Plant Health Inspection Service, which began in 2008 and has resulted in revised biosecurity practices and policies, according to James Roth, a veterinary microbiology and preventive medicine professor at ISU.The continued collaboration will disseminate new biosecurity standards and principles in two languages, improve training and education and update the USDA’s disease response plans.Biosecurity principles include buffers and separation around and within poultry houses and “manure and litter management.” And industry interests recently voted to require biosecurity audits as part of a National Poultry Improvement Plan that has been in place for decades, according to Roth.
