Must Commercially Cleaned Lettuce Still be Checked? Kosher Agency says Yes


LETTUCEChicago – The kashrus world is unanimous in requiring lettuce to be checked for insects. Agencies generally accepted the notion that pre-washed (bagged) iceberg lettuce is acceptable from any source, even if it is not certified as kosher. This is because the method of commercially cleaning leafy lettuces is sufficient to remove the insects typically found in iceberg lettuce.

However, in recent weeks, says the cRc, lettuce coming from specific regions in California have been more heavily infested than usual, and that the cleaning methods in use have not always been successful in removing all insects from the lettuce.

This has caused some kashrus agencies to temporarily remove certification from a number of brands of iceberg lettuce, of which the Fresh Express brand is the most prominent.

A cRc statement noted: “We have not been able to independently confirm these results on a national scale, but accept the findings of these hechsherim based on the research of experienced Mashgichim in multiple cities.

  1. Just looked at CRC Website.
    Seems there has been a misunderstanding, as contrary to your headline, they do not say iceberg MUST be checked, only that they RECOMMEND that it SHOULD .

    See below:

    As an extra measure of caution, we recommend that those who purchase the non-certified lettuce, should visually inspect a few, small, handfuls of lettuce from each bag before eating the rest of the contents of the bag.

  2. Because all food was checked under a microscope in the Alta heim. Get real the jewish women of europe were basically (hebrew/jewish) illiterate before the bais yacov movement. I highly doubt they knew the intricacies of kashrus.
