【Abstract】 Pigs were infected respectively with Trichinella sp. isolated from pigs and dogs in Harbin areas and the international reference strains of T. spiralis and T. nativa. Trichinella infected pork was experimentally stored at -22℃ and -32℃ respectively. It was shown that Trichinella sui from Harbin area and T. spiralis did not tolerate low temperature, the organisms all died at -32℃ for 12 hours and -22℃ for 48 hours and T. canine and T. nativa had a stronger tolerance to low temperature,the organisms died at -32℃ for 72 hours and at -22℃ for 168 hours.更多还原
