As long as people realize that this treatment with ammonia is not completely fool proof.
USDA testing
Beef can still contain deadly EColi and other pathogens despite treatment with ammonia, and other meat like poultry and pork can still also harbor food borne illness as well despite the same.
Furthermore, we don't even know who's treating with ammonia and who's not. Certainly not all because it takes money, time and specialized equipment, etc., and it also takes committment from those who believe there is a problem and want to protect the public if they can. Some holdouts still think it's not a big deal or don't care one way or the other.
Peanuts, poultry, cookie dough, strawberried, canteloupe, sprouts, spinach, etc., well who knows what's going on there. Until they figure out a bacterial "kill step" that everyone's happy with, we'll continue to see problems in these and other food items.
