[Content of carcinogenic nitroso compounds in food products].

The data are provided on the content of carcinogenous N-nitroso compounds in foods manufactured in a region with a high gastric carcinoma incidence. It was found that foods under analysis have a high content of carcinogenous nitroso compounds. The foods were also found to contain N-nitrosopiperidine, a carcinogen inducing tumors of the gastrointestinal tract.

[N-nitroso compounds in the food products in regions with a high stomach cancer morbidity].

The content of cancerogenous N-nitrosamines (NA) was examined in food marketed in the regions with the increased gastric carcinoma incidence. The food was analyzed by means of the fluorescent technique. Some of food products, such as lard, corned beef, dried mushrooms were found to be contaminated with volatile NA, while vegetable and milk products contained negligible amounts of NA or did not contain them at all.
