Abstract
The nitrite concentrations in different commercial dog foods were measured. Differences in the nitrite concentrations were observed, and were mainly attributed by the type of meat used as the main ingredient and its proportion in the final product. Standard doses for nitrite of 2.5 and 4.6 mg/kg were calculated using different methods, and these values are both much lower than the standard dose for human food. The nitrite concentrations in some of the samples in this study exceeded the 2.5 mg/kg value.
