ASKOU 10 Kosher Seminars Draw Participants from Near and Far

Where would you go if you wanted to learn the fine art of kashrut from experts, combining studies of the laws of kosher with the hands-on experiences that only those experts can provide? For dozens of rabbis and advanced rabbinical students this summer, the answer was the Orthodox Union.

Lo Basi Ella L’orer: Ein Mevatlin Issur Lechatchila

A Jew is not permitted to intentionally be mivatel any issur, even an issur d’rabbanan (Y.D. 99:5-6). Additionally, Chazal instituted a k’nas, forbidding the food for the mivatel and any intended recipient. Rebbi Ekiva Eiger (99:5) based on Teshuvas Rivash (498) includes in this k’nas any consumer for whom the product was intended for sale, and extends the k’nas not only to the food but also to require kashering keilim[1].

On June 1st, the OU hosted Rabbi Moshe Vaie, the world renowned expert in the field of hilchos tolaim and author of Bedikas Hamazon Ke’halacha.

Lo Basi Ella L’orer: Cooling Water Systems

Cooling water systems

A common way to cool products is through the use of a cooling water system. In a cooling system, ambient or chilled water is used to cool hot products. The product transfers its heat with the cooling water (for example through the use of a heat exchanger) and then the water in turn is cooled. Most cooling systems accomplish this through the use of a cooling tower. Cooling towers make use of the cooling effect of evaporating water. Allowing a small portion of the water to evaporate into a moving air stream provides significant cooling to the rest of the water. While cooling towers are efficient ways of cooling water, they are also known to breed dangerous pathogens such as legionnaire’s disease. Therefore, although as we will discuss there are situations where we need to be pogem cooling water, under no condition should anyone taste cooling water חמירא סכנתא מאיסורא.
