(NAFB)--World Pork Expo begins tomorrow (Wednesday) in Des Moines, Iowa - and in preparation - the National Pork Producers Council gathered veterinary experts together to determine the best ways to prevent the potential for disease transmission throughout the exposition. NPPC CEO Neil Dierks says the experts have assured stringent health requirements are in place for the Expo shows and sales. Attendees are asked to observe good biosecurity practices - including wearing clean clothing and shoes that haven’t been inside a pork-production facility. All swine barns and pens are also being disinfected before the pigs arrive - and will again be disinfected after the Expo. Attendees will also have the opportunity to disinfect their shoes before going home in specially designed stations near the exits.
