Why do foods kept in a refrigerator stay fresh longer than left out on the counter?

Refrigeration slows down the growth of bacteria and other microorganisms that cause food to spoil.

Bacteria grow best at temperatures between 40°F and 140°F, which is known as the "danger zone." When food is left out at room temperature, bacteria can quickly multiply and cause the food to spoil.

Refrigeration temperatures are typically below 40°F, which slows down the growth of bacteria and other microorganisms. This is why foods can stay fresh longer in the refrigerator than they can at room temperature.

Some foods, such as raw meat and poultry, are more susceptible to bacterial growth than others. These foods should be refrigerated as soon as possible after purchase and cooked thoroughly before eating.

Here are some tips for storing food in the refrigerator to help keep it fresh longer:

* Store food in airtight containers to prevent contamination from other foods or the refrigerator air.

* Keep raw meat and poultry separate from other foods to prevent cross-contamination.

* Do not store food in the refrigerator for longer than the recommended time. Check the "use-by" or "sell-by" dates on food packages.

* Throw away any food that has an off odor, taste, or appearance.
