Abstract
- This study utilized infectivity bioassays in cats and mice to assess the efficacy of inactivation of Toxoplasma gondiicysts in experimentally infected sheep meat and tissues subjected to chilling, freezing, heating, microwave cooking, and gamma ray irradiation. Heating at 60°C or 100°C for 10 minutes, freezing at either −10°C for 3 days or −20°C for 2 days, or irradiation at doses of 75 or 100 krad was sufficient to kill tissue cysts. Meanwhile, neither cooking in a microwave nor chilling at 5°C for 5 days was sufficient to kill tissue cysts.
