After receiving numerous emails from concerned readers questioning the Kashruth at a few Dunkin Donuts establishments in Brooklyn, YW called Rabbi Aaron Mehlman who is the Rav Hamachshir to verify the facts. This is exactly what transpired, and what action was taken.
A Mashgiach working for Rabbi Mehlman (at National Kosher Supervision) was conducting a routine Kashruth inspection at the Dunkin Donuts located at the Avenue U / 86th Street / Stillwell Avenue junction. While inspecting the establishment, the Mashgiach came across a newly opened, partially used box of “sharp cheddar cheese”.
This caused an alarm to go off – since the only cheese used is American Cheese. After further inspection it was noticed that the cheese was Treif.
Rabbi Mehlman quickly notified the owner of the franchise of what transpired. After a thorough investigation it was clear that an employee on an overnight shift brought the Treif cheese into the store.
Since the only place that this cheese is used is in the microwave ovens, Rabbi Mehlman informed the owner that the ovens must be shut down and Kashered. The owner started giving Rabbi Mehlman a hard time about it – complaining that it would be too difficult to bring a temporary Kosher oven from another establishment to be used temporarily.
After numerous requests to comply, Rabbi Mehlman removed his Hechsher from the Dunkin Donuts located on Avenue J and East 15th, and in the store in question – located at the junction of Avenue U / Stillwell Ave / 86th Street.
Rabbi Mehlman also stressed to YeshivaWorld that all other Dunkin Donuts which have his Hechsher hanging in the stores are 100% Kosher.
