As we reported on Saturday, pigs on display at the Minnesota State Fair were undergoing confirmatory tests to determine whether they were infected with H1N1 (swine flu). 

Earlier today, Agriculture Secretary Tom Vilsack revealed the 2009 pandemic H1N1 influenza virus was present in samples collected at the fair. Additional samples are being tested. 

At press time, the USDA believes the Minnesota case “does not suggest infection of commercial herds because show pigs and commercially raised pigs are in separate segments of the swine industry that do not typically interchange personnel or animal stock.” 

Vilsack once again is reassuring Americans that eating pork does not pose any infection dangers. 

We’ll continue to monitor the story for you.
