Abstract | ||||
Thermal inactivation of Yersinia enterocolitica in milk revealed that Yersinia enterocolitica was destroyed at 62°C after one minute of exposure, at 60°C. The thermal resistance starts to develop which increases with shorten the time of exposure as growth of yersinia enterocolitica was very good/one minute and deminished to be non detectable/five minute. The thermal death time was 45 minute at 55 C. Yersinia enterocolitica could survive in artifically contaminated yoghurt stored at refrigeration temperature (7 : 1 C) for 9 days. | ||||
