What do I do if my child touched food without Negel Vasser?
There are certain foods that are forbidden according to Halacha on the basis of danger. For example, one is not allowed to eat fish that was cooked together with meat, or meat that was cooked together with fish, as that is considered dangerous to the person. Food placed under a bed is considered dangerous as well. A Ruach Ra, a negative, impure spirit, rests on those foods. Eggs, onions, and garlic that were completely peeled and then left overnight are considered dangerous, and one should not each such foods. A Ruach Ra also rests on food that was touched by someone who did not wash Negel Vasser (except a goy to whom this law does not apply) -- and consequently it should not be eaten. The Alter Rebbe writes that one who is strict and does not eat food that was touched even by a child of the age of Bris Milah onwards without Negel Vasser, is considered Kodosh, holy.
