YONKERS, NY Microbiological tests of store-bought chickens, published in the March issue of Consumer Reports magazine, found Campylobacter, a rod-shaped bacterium and the leading cause of food poisoning nationwide, in 63 percent of the chickens tested, while Salmonella was found in 16 percent of the chickens. Those numbers include eight percent of the total number tested that had both Campylobacter and Salmonella. Only 29 percent were free from both. The testing is the most comprehensive of its kind ever published in the US, and uses a sample size of almost 1000 fresh chickens purchased at retail stores in 36 cities.
Public health officials estimate that the annual cost of illnesses caused by Campylobacter is up to $5.6 billion and salmonella is up to $3.5 billion. Campylobacter is responsible for 1.1 to 7 million food-borne infections and 110 to 1000 deaths each year. And Salmonella sickens some 700,000 to 4 million people, though its deadlier, killing up to 2000.
The two bacterial contaminants can be eliminated if the chicken is cooked to an interior temperature of 180° (breasts to 170°). But cooking a chicken to the proper temperature is only half the battle cooks have to be careful not to spread the bacteria via contaminated implements, pans, cutting boards, kitchen towels, and sponges.

In addition to bacterial contamination, Consumer Reports also tested for taste. Key findings:
Recommendations for Government action to improve chicken safety
The US. Department of Agriculture certifies a chicken as free from visible signs of disease, but not free of disease-causing microorganisms. The USDA has made several recent enhancements (the latest put into place on January 26, 1998) to inspection systems required at poultry processing plants, including testing for Salmonella, but not Campylobacter. Among measures that would make for cleaner chickens, Consumer Reports recommends:
