PORCINE EPIDEMIC DIARRHEA - USA

Frigid temperatures across a large swath of the United States this week followed by warmer conditions could aid the spread of a fatal pig disease now in 22 states, affecting hundreds of thousands of pigs, a swine veterinarian said on Thursday [9 Jan 2014].

There are no official figures for pigs lost to the disease, but U.S. hog industry analysts estimate one million to 4 million have died.
