Salmonella Contamination in Slaughterhouses

II. Four Swine Cases of Salmonellosis and Salmonella Propagation in Their Carcases

Abstract

Four pigs were found to be infected with Salmonella choleraesuis, which had been detected quite rarely in Japan, in the municipal slaughterhouses in Osaka over a half-year period ending in May, 1969. When the fresh carcases of these pigs were allowed to stand at 25-30°C for 24-48hours, salmonellae propagated from 10²/g to 10⁶×10⁷/g. Nevertheless, the carcases looked very fresh at the end of this period.
