Salmonella Radicidation of Poultry Carcasses

Résumé du livre

If "absence" of Salmonella in radiated skin samples is required a dose of 3.90 kGy is needed with irradiation at -18°C and a dose of 1.95 kGy at +50 °C. The data presented, however, show that such high doses are not necessary. Experiments have shown that the number of salmonellae per carcass will be lower than 100 cfu. An additional storage period for 1 to 3 months at -18 °C leads to a decrease in the number of salmonellae per carcass. In literature (259) it was shown that freezing resulted in an 0.5 log cycle reduction of the number of salmonellae cfu. The application of a radiation dose of 2.50 kGy does not guarantee a Salmonella -"free" end product. The microbiological quality, with respect to total counts and to the presence of potentially pathogenic microorganisms, is Improved In comparison with the untreated slaughtered product. .
