USDA secretary Tom Vilsack said swine flu can’t be contracted from eating pork as the virus is not transmitted through food.
About 65 people in the U.S., 1,300 in Mexico, and people in Canada, Europe, Asia-Pacific countries and the Middle East have been infected by the hybrid influenza.
The U.S. National Pork Board, too, has asked producers to increase biosecurity protocol in their farms.
Meanwhile, the World Organization for Animal Health stressed the flu should not be called "swine flu" as it contains avian and human components, according to a Reuters report. There are no reports of pig being infected with the disease.
