According to the USDA, if you follow food safety guidelines, you can refreeze most meat or poultry. It is safe to refreeze any uncooked meat thawed in the refrigerator; just be aware that the moisture lost during thawing may impact quality. If you cook meat that had been frozen before, it is okay to refreeze whatever you don't eat if it's kept refrigerated and then frozen within three days.
When it comes to refreezing meat, some tips:
Never refreeze meat that has been left out of the refrigerator for longer than two hours; or 1 hour in temperatures above 90⁰F.
Never refreeze meat that has fully thawed on the counter.
If you buy packaged meat, poultry, or fish from the grocery store that's been frozen, the USDA says it is safe to refreeze it if it's been stored and handled correctly.
