Plastic food storage containers are convenient and useful for saving food and cutting waste, but they could be leaching harmful chemicals into your foods. The chemical bisphenol A, or BPA, is a known hormone disruptor, and is found in plastic food storage containers more often than is comfortable. Many people who are sensitive to hormone disruptors or who simply want to avoid potentially harmful chemicals opt for glass containers, or at the very least, plastic that advertises itself as BPA-free.

Anyone certified in safe food handling knows not to place hot food in the freezer. Placing something hot, or even warm, next to cold food can cause the previously frozen food to partially thaw, which puts it at risk of spoiling. It can also raise the overall temperature of the freezer, putting all of the food at greater risk of spoilage.

Both germophobes and chefs will warn about washing poultry. When rinsing or washing poultry, the water tends to spray and splatter, which can actually contaminate more surfaces with potentially harmful chicken juice that could contain salmonella.

Fermenting food for preservation and to increase nutritional value is a technique humans have been using for millennia. The basic idea is that ambient bacteria will kick off fermentation right on your countertop if brined food is left out.

The problems come when it is done carelessly; following the basic safety precautions keeps it a low-risk process.

Nonstick pots and pans are amazing modern inventions that make cooking and cleaning a lot easier. Unfortunately, when used improperly, they can be dangerous. The coating that makes the utensil nonstick can get released into the air or food if the pan is overheated, and these chemicals are toxic when ingested. Some people stay away from them all together, arguing that cooking on a toxic surface can’t be good. Others opt for nonstick only for low- or moderate-heat cooking.

It should be common sense not to leave a flame on unattended, yet many home cooks do just that. Even though things are generally safe, leaving an active oven or stovetop on, even at a low temperature, is a big fire risk. Always stay close by and check regularly when the oven or stove is on.

Thawing frozen food on the countertop may seem like a quick way to warm up food. In reality, thawing on the countertop exposes the outer layers of food to temperatures where bacteria can breed while the center is still frozen, ultimately prolonging exposure to the dangerous temperatures. Always thaw in the fridge or in a warm water bath for efficient and safe thawing.

If you are lucky enough to have an overhead hood for your stovetop, it requires occasional care. Grease naturally accumulates in and on the hood, which can be a safety hazard if not wiped down regularly. High temperature or tall flames can actually ignite a greasy hood, causing a fire that is otherwise easily preventable.

If most of your pots and pans have heat-resistant handles, it can be second nature to grab them in the middle of cooking. Some of the highest quality cookware spreads heat evenly, including to the handles, which means even just one firm touch could cause a significant burn. Always double check by tapping the handle to see if it’s hot before grabbing it. Also, use a cloth or glove if the handles are hot.

There is actually a right and wrong way to organize your fridge. While some things are more important than others, one of the most important things to do is to keep raw meats on the bottom of the fridge.

It may sound counterintuitive to use sharper knives for safety, but sharper knives lead to fewer cuts. Dull knives create the need to use more pressure and to maneuver hands and ingredients into awkward positions, leading to a greater risk of slipping. Sharp knives cut cleanly with minimal pressure, allowing you to keep your hands free and clear of the blade.
