Can frozen hamburgers that thawed on ice in a cooler be re-frozen and then cooked eaten without making you sick?

It's not recommended to refreeze thawed hamburgers, even if they were thawed on ice in a cooler. Here's why:

* Bacteria Growth: While thawing on ice slows down bacterial growth, it doesn't eliminate it completely. Refreezing allows bacteria to multiply further, increasing the risk of foodborne illness.

* Quality Degradation: Refreezing affects the texture and quality of the meat. It can become drier and tougher after being frozen and thawed multiple times.

Safer Options:

* Cook Immediately: The safest option is to cook the hamburgers immediately after thawing.

* Keep Cold: If you need to delay cooking, keep the thawed burgers in the refrigerator at 40°F or below, and cook them within 2 days.

In short, while it might seem harmless, refreezing thawed meat can compromise food safety and quality. Always prioritize your health and cook the hamburgers fresh after thawing.
