All told, Mr. Millman and his mother, Ann Marks, gathered 213 samples of chicken drumsticks from supermarkets, butcher shops and specialty stores in the New York area.
Now they and several scientists have published a study based on the project in the journal F1000 Research. The results were surprising.
Almost twice as many of the kosher chicken samples tested positive for antibiotic-resistant E. coli as did the those from conventionally raised birds. And even the samples from organically raised chickens and those raised without antibiotics did not significantly differ from the conventional ones.
That's from this post in the NYT.
But, as the story reminds us, don't forget that:
The contamination does not mean the chicken is dangerous to eat. Generally, poultry is safe if handled carefully and cooked to an internal temperature of 165 degrees Fahrenheit, according to guidelines from the Agriculture Department
