[Content of carcinogenic hydrocarbons in smoked foods in the German Democratic Republic and the Hungarian People's Republic].

In the GDR, industrially smoked foods contain on an average 0.43 microgram Benzo(a)pyrene (BaP)/kg; products smoked according to trade rules, 0.76 microgram/kg; home-smoked products, 0.74 microgram/kg. The mean BaP content of smoked meat and sausage products in the GDR is 0.55 microgram/kg. Smoked fishes (without skin) contained on an average 1.39 microgram BaP/kg. The following average values were found in the Hungarian People's Republic: 0.6 microgram/kg (industrially smoked), 0.74 microgram/kg (home-smoked), 0.7 microgram/kg (total mean). Smoked cheese contained on an average 0.85 microgram/kg. The average BaP value of home-smoked (softwood) products of a Slovene ethnic group in the Hungarian People's Republic is 4.16 microgram/kg; the population of this region shows a considerably increased rate of stomach cancer. Apart from this particular case, the techniques used in both countries permit to obtain smoked meat and sausage products and smoked cheese with BaP contents less than 1 microgram/kg.
