Effect of cooking procedures of kiymali pide, a traditional Turkish fast-food, on destruction of Escherichia coli O157:H7

The objective of the present study was to obtain data about cooking time and temperature of kiymali pide in the restaurants and to investigate thermal inactivation of E. coli O157:H7 during experimental kiymali pide making. A field study was conducted in randomly selected 23 of 87 pide restaurants. Processing parameters including oven temperature, cooking period and post-cooking temperature were determined. Kiymali pide samples were prepared using ground beef filling experimentally inoculated with E. coli O157:H7 (7.6 log(10) CFU/g). Pide samples were cooked at a conventional oven at 180 degrees C for 180, 240, 270, 300 and 330 s. Results of the current study suggest that cooking kiymali pide at 180 degrees C for at least 330 s (5.5 min) may provide sufficient food safety assurance (>= 6 log(10) CFU/g) for E. coli O157:H7.
