I must say, cast iron was quite nice to have on a charcoal grill after Hurricane Matthew. You can't use most modern cookware on a charcoal grill. Especially not anything with non-stick coatings. As for the bacteria, I've always cleaned the cast iron. No Brillo pads, yikes! But very hot water and wiping with a clean rag, yes. If something was particularly stuck on I'd scrape it with a metal spatula first. I cannot recall ever worrying about getting sick because of cast iron cookware. Jill |

If heating destroyed all the harmful bacteria, then it would also destroy
botulism...but it doesn't...explain that. N. |

One of the best and easiest ways to sanitize cooking/food prep surfaces is to place items outdoors on a sunny day and let the sun's UV rays do their thing... excellent for sanitizing cutting boards. I have UV lamps inside my AC duct work, all the air in my house gets sanitized 24/7, we very rarely get colds and then they're mild and don't last long. I also use a UV lamp to sanitize all my domestic water, excellent for preventing all sorts of infections, internal and external... why make the OB-GYN and Dermatologist rich... the most bacterial/viral laden source in your home is your hot water heater... may as well bathe in a sceptic tank, may as well be drinking gutter water. The bottled water yoose buy at the corner store is actually the filthist water you can drink, even polluted from those fercoctah plastic containers. |

It's amazing how many folks post on this newsgroup who have no clue of WTF they're talking about! Not only does heat destroy botulism, canneries routinely put live botulism bacterium (and others) in specially marked cans, run 'em thru the cook cycle, then check to see if all bacterium is COMPLETELY DEAD! It's what determines cook temps/times are necessary to safely can food products. Also note, "under low-oxygen conditions", like in canned foods. And yes, having worked in a cannery, I've actually done this test. This is a non issue with a cast iron skillet, unless N2 wants to cook on cast iron in a spaceship that's losing its life support. ![]() nb |

From the article you linked: Though spores of Clostridium botulinum are heat-resistant, the toxin produced by bacteria growing out of the spores under anaerobic conditions is destroyed by boiling (for example, at internal temperature >85°C for five minutes or longer). Therefore, ready-to-eat foods in low oxygen-packaging are more frequently involved in botulism." Heat destroys the toxin but not the spores that produce it. |

The bacteria can exist as a vegetative cell or a spore. The spore is the dormant state of the bacteria and can exist under conditions where the vegetative cell cannot. When conditions are right, the spore will grow into the vegetative cell. When the vegetative cells grow to high numbers, this bacteria produces the toxin. The vegetative cells of Clostridium botulinum are destroyed by heat but the spore is very resistant to heat. Temperatures well above 100°C (212°F) are needed to destroy the spore. " https://www.fsai.ie/faqs/botulism.html#botulism6 "Does cooking kill Cl. botulinum and its toxin? Normal thorough cooking (pasteurisation: 70°C 2min or equivalent) will kill Cl.botulinum bacteria but not its spores. To kill the spores of Cl.botulinum a sterilisation process equivalent to 121°C for 3 min is required. The botulinum toxin itself is inactivated (denatured) rapidly at temperatures greater than 80°C . " Heat DOES destroy the bacteria, the toxin, and the spore. In any case ,cooking fresh raw food in an open cast iron pan is never going to create the conditions required to produce botulism.

The spores are pretty small, so don't need much to live on. The spores themselves are not toxic but heat destroys the toxins. |
