If it stinks when I cook it, I would throw it out. Any bacteria will be killed during cooking. If it smelled OK but I still didn't quite trust it, I'd pressure cook it and make a big batch of chicken soup. I'm not sure that even streptococcus toxin (the most heat stable spoilage product I can think of) will survive half an hour in a pressure cooker. Best regards, Bob |

Commercial packaged chicken isn't "frozen," it's "superchilled."=20 That's the silly trade term. It's "superchilled" to a rocklike texture=20 and bears a remarkable resemblance to "frozen" chicken. The poultry=20 and fish cases at Costco are generally kept at 33F to 35F. The=20 "superchilled" granitic chicken is put into the cases as delivered.=20 The poultry packers discovered that superchilling their products=20 killed some bacteria, seriously slowed others and extended the shelf=20 life in stores. We don't know the beginning temperature of the product as purchased in=20 the post, nor do we know the final temperature as it was put into the=20 fridge. > 5 hrs > in a car (where it would probably be a good deal warmer than the > ambient 60-65F mentioned) We have no way of knowing that. Was it sunny? Was the car closed? Was=20 the chicken in the path of an operating heater? Was it in a cardboard=20 box with other cold foods?

Since a startling percentage of chicken > sold in the US has an appreciable amount of Salmonella bacteria to > start out with, the 'safe' time at various temperatures on this chart > has no practical relevance. Yes, it's for cooked food but it makes two important points. First;=20 that there isn't much bacterial contamination in cooked food (so=20 cooking it drastically reduces and controls that "appreciable" amount=20 of bacterial contamination, see last reference below) and, second; the=20 growth rate isn't as fast as most people think. If the chicken=20 actually did get to 65F, the total number of bacteria would double in=20 2 hours thereafter. But that doesn't matter because cooking it to more=20 than 160F makes it safe. In my original note, I sent the same thing twice. My mistake. Here's=20 what I meant to send the first time. This other chart deals with=20 thawing frozen birds at room temp. While we don't know that the=20 chicken necessarily was frozen when purchased, the situation vis a vis=20 bacterial growth in frozen and room temp thawed chicken is germane=20 here. This is a small part of the paper, for full details, go to: <http://www.hi-tm.com/Documents/Thaw-counter.html> <<<<<<<< begin quote >>>>>>>>>>>> Differences in bacterial population before freezing and after thawing=20 were assessed. The aerobic plate count, Enterobacteriaceae, and=20 pseudomonad populations of the skin of uninoculated chickens did not=20 increase when the chickens were thawed on the counter in less than 10=20 hours to an internal temperature of 40F within the breast. The most=20 notable observation was that there was a small increase (0.5 log10=20 CFU/g) in the population of pseudomonad bacteria (spoilage bacteria)=20 when the chicken was thawed under refrigeration, which took about 55=20 hours. In another part of this study, chickens were inoculated with=20 Salmonella hadar in order to assess the effect of the different=20 thawing methods on the growth of this microorganism. It was shown=20 that there was a slight decrease in the population of Salmonella=20 hadar-inoculated chickens frozen and thawed at room temperature to an=20 internal temperature of 40F within the breast. This same decrease was=20 noted in chickens frozen and thawed in flowing water and in=20 refrigeration. This latter observation demonstrates the reduction in=20 cell numbers because of freezing injury and the inability of this=20 strain of salmonellae to grow below 45F. In summary, the research study by Jim=E9nez et al. (1999) supports the=20 previous study by Klose et al. (1968). The USDA is correct to allow=20 raw meat, fish, and poultry to thaw at room temperature. There is no=20 risk in thawing these products at room temperature. <<<<<<<<< end quote >>>>>>>> From another paper: <http://www.hi-tm.com/homeprep/home-VI.html> <<<<<<<<<< begin quote >>>>>>>> Keeping food at 50F for a short period of time, say 1 hour, is a=20 spoilage problem, not a food safety problem." <<< snip >>> [And, if the food is held at 50F or more and it noticeably spoils, can=20 it be made safe?] If Raw Food Is Spoiled High numbers of spoilage bacteria in raw food will NOT make you sick.=20 When food spoils microbiologically, the spoilage microorganisms grow=20 on the surface until they totally cover the surface, perhaps 2 to 3=20 layers deep. At this point, surfaces of foods such as meat, poultry or=20 fish feel "slimy", and there can be 20,000,000 to 50,000,000=20 microorganisms per gram or per square inch of food.

For this reason, spices and herbs have been added to=20 food throughout the centuries to mask the off-flavors and off-odors of=20 spoiled or partially spoiled food.

Just because cooking spoiled food kills the bacteria does not make it safe to
eat. Bacteria also produce toxins that cannot always be neutralized by cooking. |

That's why the USDA says to cook home-canned foods for 10 minutes before service. But you aren't likely to find botulism in raw chicken since it's an anaerobe. There's a difference between pathogenic (harmful) and spoilage bacteria. They function independently of each other. Simultaneous but different processes. Pastorio |

I knew that. :-) It's most common in canned foods, not fresh raw, and anaerobes produce gas which causes the ends of the cans to bulge. Never EVER eat a bulgy can! Don't even open it. But, are you sure that Botulinum toxin is destroyed by cooking? I understood that it was not??? > > There's a difference between pathogenic (harmful) and spoilage > bacteria.

This is one reason that dad has sworn off beef. He believes that "aged" beef is rotten and full of carcinogens. No, this is not MY belief, but I find his viewpoint interesting... :-) K. -- >^,,^< Cats-haven Hobby Farm >^,,^< >^,,^< "There are millions of intelligent species in the universe, and they are all owned by cats" -- Asimov Custom handcrafts, Sterling silver beaded jewelry http://cgi6.ebay.com/ws/eBayISAPI.dl...s&userid=Katra |

They eat carrion and maggots. It's awfully hard to poison one... If any meat was on MY floor for more than 5 seconds, it'd be cat food. :-) K. -- >^,,^< Cats-haven Hobby Farm >^,,^< >^,,^< "There are millions of intelligent species in the universe, and they are all owned by cats" -- Asimov Custom handcrafts, Sterling silver beaded jewelry http://cgi6.ebay.com/ws/eBayISAPI.dl...s&userid=Katra |

My interpretation of the rule is that it goes into my mouth, but the pot is as good a destination as any if it's not cooked through. |
