Aaron,
There is a big issue with nitrites and human health. Where there are nitrates there are have to be nitrites. A lot of the dairy industry was chased out of California because of nitrite contamination of the groundwater. Nitrites were implicated in the death of a few infants in California. They inhibit the action of hemoglobin, similar to the way that cyanide and carbon monoxide do.
As a side note, guess where a lot of those Cailfornia dairymen ended up? You guessed it, Texas, especially up in the Stephenville area.
