US - United States Agriculture Department tests show a type of salmonella found in eggs is turning up more often in chicken meat. From 2000 through 2005, there was a fourfold increase in positive test results for salmonella enteritidis on chicken carcasses.

"It still continues to rise, even though the overall incidence of salmonella in general has fallen," said Richard Raymond, the Agriculture Department undersecretary for food safety. "It's one that we still don't have all the scientific evidence we need to know how best to attack it.

"Even though that particular bug is going up, the overall incidence of food-borne illness from salmonella is declining, and the amount of salmonella positives has shown a dramatic drop."

Salmonella sickens at least 40,000 people and kills about 600 every year in the United States.

Many different salmonella bacteria make people sick, but salmonella enteritidis is one of the most common. It causes fever, stomach cramps and diarrhea. In vulnerable people, infection become deadly by spreading beyond the intestine to the bloodstream.

At one time, eggs became contaminated with salmonella on the outside from contact with fecal bacteria. But in recent years, the salmonella enteritidis strain has been found inside intact, disinfected, grade A eggs.

This type of germ contaminates eggs inside a hen's ovaries, before shells are even formed.

Now the germ is turning up in broiler chickens, the kind used for meat, according to research by the Agriculture Department published in the December issue of the Emerging Infectious Diseases journal of the Centers for Disease Control and Prevention.
