The Nizhny Novgorod Reference Center of Rosselkhoznadzor has found Salmonella in pork ham samples, and the contaminated products will not be circulated. The center will report the finding to the automated system "Vesta" and the interregional Department of Rosselkhoznadzor. Salmonella can cause food poisoning in humans and can be introduced into food production through contaminated raw materials or poor hygiene by workers. It cannot be detected by taste or color, and refrigeration cannot destroy it. However, it can be destroyed with ultraviolet radiation and prolonged heat treatment.
