A common Kashrus Dilemma?
The machines were running almost 24/6 at Mandel’s Matzah Factory. In the months before Pesach, tons of matzah were being produced.
One day, the factory mashgiach (kashrus supervisor) received a recall notice regarding a certain shipment of flour, about which there was a serious kashrus question. He checked the code and realized a large number of runs had already been made with the questionable flour.
Immediately upon hearing this, the mashgiach halted the production. “There was a recall notice on the flour we’ve been using,” he notified Mr. Mandel.
The mashgiach then contacted his superior at the supervising kashrus agency. “There is an urgent kashrus question at Mandel’s Matzah Factory,” he said. “There was a recall notice on the flour we’ve been using. We’ve already produced over a ton of matzah from that flour shipment.”
The halachic advisory board convened. After a tense hour of debate, they ruled that the matzos were permitted b’dieved (de facto) based on a combination of lenient opinions, in consideration of the great potential loss (hefsed merubeh). However, they prohibited baking any more matzos with that shipment of flour.
