Ammonia in beef used at fast-food restaurants and schools

Recently, the New York Times ran a very interesting (in a gross way) article about a company in South Dakota that treats beef scraps with ammonia. The treated beef scraps are then made into a paste and used in beef products which are served at fast-food restaurants and school. The ammonia is supposed to kill any e.coli and was considered so effective that the company was exempted from testing. Well, as it turns out, not only is this process disgusting it’s also ineffective.  Grist has the full story.
