Thawing Frozen Foods

Use only an approved thawing method and keep to its conditions.

12 steps7 criticalLimit variesAlways tested

Steps

  1. 1Critical stepChoose an approved thawing method: refrigeration, completely submerged under running water, microwave then immediate cooking, or as part of cooking
  2. 2Refrigerator thawing: keep the food at 41 degrees F (5 degrees C) or below the whole time
  3. 3Plan ahead for refrigerator thawing because large items can take several days
  4. 4Critical stepVacuum-sealed frozen fish labeled to be kept frozen: remove it from the package before thawing under refrigeration
  5. 5Critical stepRunning-water thawing: submerge the food completely
  6. 6Use water at 70 degrees F (21 degrees C) or below, flowing fast enough to agitate and float off loose particles
  7. 7Critical stepDo not let thawed portions of ready-to-eat food rise above 41 degrees F; watch the food while it thaws
  8. 8Critical stepRaw animal food that will be cooked may be above 41 degrees F for no more than 4 hours in total, counting time under running water and preparation for cooking
  9. 9Microwave thawing: move the food straight to conventional cooking with no interruption
  10. 10Critical stepCooking from frozen: cook it as the cooking rules require for that food, to its required minimum internal temperature
  11. 11Critical stepDo not thaw on the counter at room temperature or in standing water; neither is on the Food Code list of approved methods
  12. 12Keep thawed food at 41 degrees F or below until it is cooked or being prepared

What graders are watching for

Tips
  • As thawing normally takes more than four hours, thaw properly to limit bacterial growth; outer portions warm faster than the middle
  • For refrigerator thawing, plan ahead: large items may take several days
  • Room-temperature thawing and standing water are not on the Food Code list of approved methods; if you are unsure, use refrigeration

Common mistakes

  • Thawing on the counter or in a sink of still water. Neither is an approved method.
  • Running water that is too slow to carry off loose particles, or warmer than 70 F.
  • Forgetting that preparation time counts toward the 4-hour limit for raw animal food thawed under running water.
  • Microwave-thawing food and then setting it aside before cooking.
