Prevalence of antibiotic-resistant E. coli in retail chicken: comparing conventional, organic, kosher, and raised without antibiotics

The average teenage boy is likely to have an interest in chicken only when it hits his dinner plate.
But after a trip to Israel for his sister’s bat mitzvah, Jack Millman came back to New York wondering whether the higher costs of kosher foods were justified.
“Most consumers perceive of kosher foods as being healthier or cleaner or somehow more valuable than conventional foods, and I was interested in whether they were in fact getting what they were paying for,” said Mr. Millman, 18 and a senior at the Horace Mann School in New York City.
That question started him on a yearlong research project to compare the prevalence of antibiotic-resistant E. coli bacteria on four types of chickens: those raised conventionally; organically; without antibiotics, and those slaughtered under kosher rules. “Every other week for 10 weeks, I would go and spend the entire Saturday buying chicken,” he said. “We had it specifically mapped out, and we would buy it and put it on ice in industrial-strength coolers given to us by the lab, and ship it out.”
