Introduction
Food safety is a field where conventional wisdom and actual science frequently diverge. Some practices that seem obviously safe are actually risky, and some precautions that seem unnecessary are actually important. Here are six food safety myths worth correcting — according to the USDA.
Myth 1: If It Smells Fine, It’s Safe to Eat
This is the most dangerous food safety myth in common circulation. According to the USDA Food Safety and Inspection Service (FSIS), many of the most serious foodborne pathogens — Salmonella, certain strains of E. coli, and Listeria monocytogenes — produce no detectable odor, no color change, and no texture change in food.

The smell test is useful for detecting food that has obviously spoiled, but it is not a reliable safety check. Following USDA storage guidelines — which you can look up for any food at FreezerOrFridge.com — is the only reliable way to ensure food safety.
Myth 2: You Can Never Refreeze Thawed Meat
The truth here is more nuanced than the myth suggests. According to the USDA FoodKeeper database, you cannot safely refreeze raw meat that was thawed at room temperature — but you can safely refreeze raw meat that was thawed in the refrigerator, as long as it was never left in the danger zone. (Source: USDA FSIS — Freezing and Food Safety)
Additionally, cooked food that was previously frozen can always be refrozen after cooking. The rule is about bacterial growth during thawing, not about the act of freezing itself. Check our beef, chicken, and pork storage guides for specific thawing and refreezing guidance.
Myth 3: Marinating at Room Temperature Is Fine
According to the USDA FSIS, marinating meat, poultry, or seafood on the counter is a genuine food safety risk. The USDA explicitly recommends marinating in the refrigerator — not on the counter — to keep food at a safe temperature during the process. (Source: USDA FSIS — Marinating)
If a recipe calls for room-temperature marinating, limit it to 30 minutes maximum and keep the food covered. Never reuse marinade that has been in contact with raw meat — either discard it or boil it vigorously for several minutes before using it as a sauce.
Myth 4: Washing Raw Chicken Reduces Bacteria
The USDA actively recommends against washing raw chicken, and for good reason: washing spreads bacteria rather than eliminating it. According to the USDA FSIS, the splashing water that comes off a chicken breast in your sink can spread bacteria up to three feet in every direction — contaminating your sink, countertops, other food, and even your clothes. (Source: USDA FSIS — Chicken from Farm to Table)
The only reliable way to eliminate bacteria from raw poultry is cooking it to an internal temperature of 165°F. See our chicken storage and safety guide for complete USDA recommendations.
Myth 5: The Five-Second Rule
Food dropped on the floor picks up bacteria immediately upon contact — there is no meaningful grace period. Research published by Rutgers University found that bacteria transfer to food within milliseconds of contact, regardless of how quickly the food is picked up. The number of bacteria increases with contact time, but the difference between one second and five seconds is not significant from a safety standpoint.
When food falls on the floor, whether it’s safe to eat depends on the food itself (moist foods pick up more bacteria than dry foods), the cleanliness of the floor, and your own risk tolerance — not how quickly you pick it up.
Myth 6: Alcohol in Food Kills Bacteria
Adding wine to a marinade, cooking with spirits, or making a flambé does not make food safe from a microbial standpoint. According to the USDA FSIS, the alcohol concentrations in cooking are far too low to have meaningful antimicrobial effects, and most of the alcohol evaporates during cooking anyway.

Apply the same food safety standards to alcohol-containing dishes as you would to any other food. Wine-braised chicken is subject to the same leftover storage rules as any other cooked chicken — check our cooked chicken storage guide for USDA timelines.
Conclusion
Food safety myths persist because they’re often built on partial truths or wishful thinking. The USDA guidelines exist precisely because intuition and tradition aren’t always reliable guides to what’s actually safe. When you’re unsure, check FreezerOrFridge.com or the USDA’s food safety resources — the answers are always based on science, not folklore.
