- Question: [Friday 11th Tamuz 5780]
May one buy Challahs from a store that does not make sure that its workers wash their hands in the morning?
The above worry is only with Jewish workers, and even then, the custom is to be lenient. Nonetheless, certainly if another bakery is available in which the workers are all Frum, or the Mashgiach makes sure that all Jewish workers wash their hands, then it is better to buy from them.
