Chicago (Reuters) - The sudden and widespread appearance of a swine virus deadly to young pigs - one never before seen in North America - is raising questions about the bio-security shield designed to protect the U.S. food supply.
The swine-only virus, the Porcine Epidemic Diarrhea Virus (PEDV), poses no danger to humans or other animals, and the meat from infected pigs is safe for people to eat.
