MCCURDY,* KATRINA FINLEY and TIFFANI ZEMMER School of Family and Consumer Sciences, University of Idaho, 103C Niccolls Bldg., P.O. Box 443183, Moscow, ID 83844-3183, USA SUMMARy INTRODUCTION Consumers have developed Escherichia coli O157:H7 infections from consumption of undercooked ground beef. The most well known case is that in which over 500 consumers became ill and four died in 1993 as a result of consuming undercooked ground beef patties at a fast food chain (5). In 2002, home preparation of E. coli O157:H7-contaminated ground beef sickened 28 consumers and caused a nationwide recall of 18.6 million lbs of fresh and frozen ground beef and beef trimmings (6). During 2007, there were 19 recalls of ground beef totaling over 30 million pounds, of which less than 3 million pounds was recovered (23). Outbreaks from E. coli O157:H7 are most commonly linked to beef; during the period 1990 to 2005, 56% of E. coli O157:H7 outbreaks were attributed to beef (8). Cases of consumer illness from ground beef consumption continue to be reported, with recent cases of illness associated with ground beef purchased at retail meat cases of a large midwest grocery chain (22). Cooking instructions on 37 retail packages of frozen ground beef patties were recorded at 16 retail stores in four western states. The labels of eleven packages contained suggested cooking times, which varied from 1.5 to 8 minutes per side for 113 g patties. Times required to cook frozen patties to 71.1°C were determined using consumer conditions, including a fry pan on an electric stove and a propane grill. Variables included initial temperature of the frozen patty, pre-heating of the fry pan, cooking temperature, and patty fat content. The patty internal temperature was measured with five beaded wire type K thermocouples (TC). The average time required to cook a frozen (-18°C) 113 g 20% fat ground beef patty to 71.1°C (as registered on all five TCs) was 7 min 39 s when the pan was pre-heated to 163°C (medium stove burner setting). Starting with a 20°C pan increased average cook time by 4 min. Starting with a -26°C patty did not significantly affect cook time. Patty cooking times on a propane grill were more variable than those in a fry pan on an electric stove. The cooking times suggested on labels of three of the packages would be inadequate to produce a safely cooked patty.
