Antimicrobial agent for food products
As early as in 1895 it was known that ammonia was “strongly antiseptic .. it requires 1.4 grams per litre to preserve beef tea.”[44] Anhydrous ammonia has been shown effective as an antimicrobial agent for animal feed[45] and is currently used commercially to reduce or eliminate microbial contamination of beef.[46][47][48]The New York Times reported in October, 2009 on an American company, Beef Products Inc., which turns fatty beef trimmings, averaging between 50 and 70 percent fat, into seven million pounds per week of lean finely textured beef by removing the fat using heat and centrifugation, then disinfecting the lean product with ammonia; the process was rated by the US Department of Agriculture as effective and safe on the basis of a study (financed by Beef Products) which found that the treatment reduces E. coli to undetectable levels.[49] Further investigation by The New York Times published in December, 2009 revealed safety concerns about the process as well as consumer complaints about the taste and smell of beef treated at optimal levels of ammonia.[50]
Grass-fed animals produce as much as 80% less of the strain as the corn-fed animals.
Ammonia! But of course! Why wouldn’t we use ammonia to kill the E. Coli?!
