[Determination of the N-nitrosamine content in meat and meat products].

Samples of meat and meat products for the content therein of carcinogenic N-nitrose-amines were subjected to a fluorometric analysis. In case of positive results the presence of NA was confirmed by cromate-mass-spectrometric and/or mass-spectrometric methods. The mean value for the concentrations of dimethyl-nitrose-amine, diethyl-nitrose-amine and nitrose-piperidine in meat products is within the ranges of 1.5-5.4, 1.0-6.1, 0.9-23.4 gamma/kg, respectively. NA was not found in meat.
