An economist at Iowa State University says unfounded concerns that pork products may be tied to the H1N1 influenza outbreak are starting to be reflected in the market place. John Lawrence is director of ISUs Beef Center. He says the market price of hogs has declined by nearly $5, per hundred weight since late April. Lawrence says the decline comes at a time of year when pork prices usually rise, and continue to increase into the summer. He says biosecurity is a high priority for Iowa Pork producers, and the outbreak will reinforce the awareness of tactics needed to ensure safety in U.S. products.
