The bad news from a new study is that two thirds of store-bought chicken was found to be contaminated with potentially harmful bacteria. The good news is that, believe it or not, the numbers are better than two years ago, when eight out of 10 chickens were found to contain pathogens like salmonella and campylobacter.

The study, to be published in the upcoming issue of Consumer Reports, tested 382 broiler chickens bought from 100 stores around the country. Some brand-name chickens -- Tyson and Foster Farms -- fared poorly, with salmonella and campylobacter found in more than 80 percent of the samples. Perdue chickens did a little better -- 56 percent of chickens tested were found to be free of both pathogens. According to the study, organic "air-chilled" broilers seemed to be a consumer's best bet because 60 percent of those chickens checked in bacteria-free.

Estimates from the Centers for Disease Control and Prevention say more than a million people have salmonella poisoning every year from a variety of causes. About 25,000 people get so sick they seek treatment at a hospital and about 500 people die every year. Symptoms of an infection generally show up 5-7 days after contamination and can include diarrhea, stomach cramping and fever.

The news that everyday store-bought chickens can be contaminated with harmful bacteria drew a loud "ewww" from several moms shopping for chickens at a local supermarket in Ashland, Mass.
