The US’s National Pork Board said it was safe to eat pork as though as the meat has been properly cooked. The virus will be killed at temperatures of 160 degrees and higher.

The US pork producers have to protect its industry of $5 billion p.a. Pork producers, handlers, and everyone else down the line are urged to observe proper measures in processing pigs and pork. Farm workers are encouraged to shower before and after work. They should leave their farm footwear and clothing only for use on the farm. This may limit the transmission of virus through material.

In the US, swine flu was not transmitted from swine to human but rather human to human.
