Ammonium hydroxide is produced naturally and is present in meat despite any production process at all. It's in just about everything you eat, to some degree.

Ammonia based compounds are naturally occurring and can be found in every component of a bacon cheeseburger (bun, bacon, cheese, condiments, and beef). Baked goods, including breads will have ranges from 400 to 32,000 ppm (for the sake of illustration, we'll use the low end of the range). Bacon has approximately 48,000 ppm nitrogen (nitrates), with 160 ppm in the form of ammonia. Condiments, relishes, and cheeses have levels up to 8,000 ppm (for the sake of illustration, we'll use 400 ppm for the condiments and 1,000 ppm for American cheese). Between the naturally occurring levels and small amounts used in our food safety system, beef may have about 200 ppm. So, for the illustration, we've taken these amounts and multiplied by the weight of the typical bacon double cheeseburger to show the full picture.

Bacon Cheesburger
Bun - 2 oz = 50 mg (440 ppm)
Bacon - 1 oz = 16 mg (160 ppm)
Condiments – 2 oz = 50 mg (400 ppm)
Cheese – 1.5 oz = 76 mg (813 ppm)
Beef – 3.2 oz = 40 mg (200 ppm)

This is really nothing new. In fact, the presence or use of ammonia in foods has been studied for years. For example, the table below contains information developed in 1973 as part of a study printed in The American Journal of Clinical Nutrition.
