Spouse and I have a discussion on what to do after you pour a sauce out of a glass bottle. I do nothing but my wife takes her finger and wipes the excess from the bottle before she puts the lid back on. I think touching the food is disgusting and she thinks leaving it there to gum up the lid is disgusting. What do people do?
If you touch food prior or during cooking then the cooking process is killing the bacteria. You shouldn’t really touch after but even in that situation a small amount of bacteria in food that’s about to be eaten isn’t the worst. The big issue is bacteria introduced to food which is then stored where the bacteria then grows over time.
