Half a billion eggs recalled in salmonella scare

3:01 pm on 21 August 2010

Half a billion eggs have been recalled in an investigation into a salmonella outbreak in several states of the United States.

Two farms in Iowa that supply millions of eggs under a variety of names in 14 states have made the recalls.

Food regulators say salmonella cases have increased threefold since May. They say 2000 cases were reported between May and July, roughly 1300 more than usual.

Salmonella poisoning can be deadly for people with compromised immune systems, but no deaths have been reported.

Bacteria growing both inside the egg and on the shell can be passed from seemingly healthy chickens.
