Nasogastric Feeding and Kashrut

לכבוד הרבנים ומרן הגאב׳ד שליט׳א

A patient who is being fed through a nasogastric (NG) tube: does he need to check as to whether the feed contains only kosher ingredients or not? Most are milk based

Many Thanks


No, this form of ingesting is not considered eating according to halacha and there is no kashrus concern.


See Shu”t Tzitz Eliezer 14:70, Maharsham 1:123, Achiezer 3:61, who rules that even Basar Bechalav which does not require “derech achila” to violate the prohibition, nevertheless it must be eaten through the throat without something blocking.

See Mishna Lamelech, Hilchos Maachalos Assuros 14 -12 who proves from the halacha that although one who swallows Mataza fulfills his obligation, one who wraps up Matza in a non food item and swallows it such in fact does not fulfill his obligation. As long as the food does not come in contact with his mouth and throat this is not considered an act of halachic eating, and so he has no “eaten” matza. The same would be true with regards to non kosher foods. See also Minchas Chinuch 313:2. 

See Shaarei Teshuva 197:8.
