Sanitation

Sanitation is removing dirt and microbes you can wash off, then not inviting them back with time and warmth. It is not a mood or a substitute for a labeled sanitizer procedure.

Hands, time, leftovers #

USDA FSIS: leaving perishable food out lets bacteria such as Staphylococcus aureus, Salmonella, E. coli, and Campylobacter grow; the danger zone is 40–140 °F; two hours (one if above 90 °F) is the refrigeration rule; leftovers cool in shallow containers ¹. Wash hands. Keep raw meat from ready-to-eat food. That clock is not dough DDT — see Temperature measurement.

Jars are a different cleanliness #

NCHFP/USDA canning safety starts with selecting and washing food and using a researched process; washing does not kill botulinum spores ². Clean jars are necessary and not sufficient. Use the process times in Canning and Food safety.

Dairy utensils can be too “clean” #

FAO: dirty milking tools survive as a problem even after pasteurization talk; rinsing matters because cleaning agents and disinfectants left in cheese milk kill the lactic acid bacteria you need ³. Sterile and empty of sanitizer are both requirements. Cheese is the craft.

Drying still wants a clean dryer and food-grade storage; dry is not sterile. Preserving is the branch.

Observe: soap, rinse, visible soil gone, perishable food back in the cold. Failure: a sponge that smells, a vat that smells of bleach, a stockpot of soup at room temperature “until it cools.” Quality dirt and safety dirt are both dirt. Only one has a tested process when you can.
