Pigs at the Minnesota state fair have tested positive for the H1N1 "swine" flu virus in preliminary tests.

Confirmation tests are pending, but this could be bad news and cause panic within the pork industry. Pork belly futures and companies like Smithfield Foods (NYSE: SFD), Tyson (NYSE: TSN), and Hormel (NYSE: HRL) are a few that could be affected.

Late Tuesday, Carnival Corporation (NYSE: CCL) reported that it will temporarily cancel all stops in Mexico due to fears surrounding the swine flu. "We have decided to cancel calls at Mexican ports for all current sailings. Additionally, we will cancel calls in Mexico for all voyages departing Thursday, April 30 through Monday, May 4," the cruise line operator said in a statement.

Carnival isn't the only cruise line playing it safe. Sector peer Royal Caribbean Cruises Ltd. (NYSE: RCL) also announced plans to temporarily suspend port calls in Mexico. Currently, the World Health Organization (WHO) has not recommended any travel restrictions to halt the swine flu's spread.
