Kosher chicken much safer

An enquiring mind led to a plucky US teenager discovering that kosher chicken is half as likely to carry dangerous E.coli virus
by ANT KATZ | Oct 16, 2013

17-year-old Jack Millman and his mother rode around metropolitan New York and bought up vast quantities of raw chicken. But Millman and his mom, Ann Marks, didn't cook the poultry. They put it on ice and shipped it overnight to a lab in Arizona, which tested it for antibiotic-resistant strains of the E. coli bacteria.

 The Philadelphia-based JEWISH EXPONENT published the amazing story on Tuesday about how and why this mother and son team became involved in their unique experiment.

The study, which included 213 samples of raw chicken purchased at 15 locations in the New York area, found that kosher chicken has nearly twice the frequency of antibiotic-resistant strains as non-kosher. The results were first published in the journal F1000 Research in July.

Kosher chicken carries half the risk

The findings are perplexing. Kosher laws contain no requirements about how chickens are raised, and the only difference between kosher and conventional poultry is in the slaughtering and de-feathering.

Lance Price, a microbiologist with Translation Genomics Research Institute in Phoenix who helped design the study, suggested that kosher companies may be sourcing from producers or hatcheries that use more antibiotics.

But Joe Regenstein, a food scientist at Cornell University, and Timothy Lytton, the author of a recently published book on the kosher food industry, dispute that notion.

Writing recently in Food Safety News, Regenstein and Lytton say a more likely explanation lies in the kosher method of feather removal.

Most poultry is placed in scalding water before plucking, but kosher poultry is dry plucked or soaked in very cold water due to restrictions prohibiting any form of cooking before the meat has been soaked and salted.

“Immersion in scalding water prior to plucking of non-kosher poultry production reduces microbial load, by either washing microbes away or by killing them, which might account for differences between kosher and other production methods,” Regenstein and Lytton wrote.

His interest stems from Israeli holiday

Millman, 17, who does not keep kosher, told JTA in an interview between classes at the prestigious Horace Mann School that he was “very surprised” by the findings.  The Manhattan resident first became interested in kosher issues a few years ago during a family trip to Israel.

“While we were there, we were eating a lot of kosher food, and I was interested in whether kosher is healthier,” he said.

Interested in exploring the question, Millman approached his uncle, Bruce Hungate, a biology professor at Northern Arizona University. Hungate, the director of the university’s Centre for Ecosystem, Science and Society, connected him to Price.

Together they designed an experiment to test 10 brands of chicken in each of four categories. Millman did not perform the actual lab tests, but he collected the samples, visited the lab and took the lead in writing up the results.

He also presented the findings at the American Society for Microbiology conference in Denver this year.

Millman and the professional scientists with whom he partnered acknowledge that the study, with its relatively small sample size, is not intended to offer the final word on the topic.

 “This was big enough for a pilot study, and the finding was dramatic and consistent enough to indicate a problem,” Price told JTA. “Of course there’s a need to follow up with a larger study and larger sample.”

“I learned the importance of asking good questions”

Price said that because the drugs used by companies to raise chickens are "considered a trade secret” in the United States, provided they use FDA-approved antibiotics, it is difficult for researchers to track. He noted that 13.6-million kg of antibiotics are used each year in meat production, compared to just 3.5-million used for human medical purposes.

Millman said he isn't sure whether more research with raw chickens is in his future, though he remains concerned about the overuse of antibiotics in meat production and its implications for consumer health and the emergence of drug-resistant bacteria.

Having varied interests, the high school senior has yet to decide whether he will major in the sciences in college.

 “I guess the most important skill that I learned is the importance of asking good questions and being willing to follow where your curiosity takes you,” Millman said.

    Your penchant to positively spin everything Jewish generally and avoid anything controversial in  our community may have gone too far in this article. In fact it borders on a lie as the whole tenor and import of the study shows that kosher chicken in fact contains 2x the amount of antibiotic RESISTANT strains of e- coli which in as far a I understand it makes it more likely that one may get ill from eating it than the non kosher equivalent. As in most things accuracy in the news is a necessity not an option.

    Shalom Max, thank you for sharing your opinion – something this website is built around encouraging. Your scientific observation may have validity, which we shall look into. I am not sure if your reference to "you" in this case is directed at the website (which is only days old); or to myself as a career-journo. But I can assure you that, in either event, your assertion that a "penchant to positively spin everything Jewish generally and avoid anything controversial in our community" is quite incorrect in either event.
    With this in mind, I would encourage, nay, challenge you to submit anything you feel should be said and isn’t – either directly to me at online.editor@sajr.co.za or to the editor in chief at Geoff@sajewishreport.co.za – and put us to the test. The shared belief of the editorial staff and the board of directors is that all views should be heard – as long as they are legal, decent, and neither espouse the destruction of Israel or of Jewish souls.
