Your Food Storage Containers Might Be Exposing Your Leftovers to Bacteria—Here Are 6 That RDs Always Buy

There are a myriad of household items that harbor a ton of bacteria. Kitchen sponges, bathroom towels, and toothbrushes, just to name a few. But there’s one common good that doesn’t get nearly as much bad PR as the rest. That bacterial vessel that goes undetected? Food storage containers. In addition to food stains and foul odors, food storage containers are more susceptible to bacterial growth, according to Kate Reeder, MCN, RDN, LDN, a registered dietitian and ServSafe Certified Instructor and Proctor at Elite Food Safety Training.

“This [bacterial growth] can happen when storage containers have hard-to-get-to spots, such as crevices in lids and narrow lips around the edges of containers,” says Reeder. Harder-to-reach crevices and corners may be harder to clean, leaving those areas vulnerable for bacteria to proliferate. Additionally, the material of the food storage containers can predispose not-so-good microorganisms to lurk.

“Plastic is a porous material, meaning that it actually has super tiny holes in it, which allow particles to pass through and be absorbed,” Reeder adds. These small, narrow places can make it difficult to clean, cooking up the perfect environment for bacteria to grow. Since glass is nonporous, bacteria will have a harder time sticking around.

We tapped an RD for their input and what to look for in a bacteria-resistant food storage container. Here are six containers that prevent bacteria from playing Dance Dance Revolution with your food.

Bayco, Glass Food Storage Containers (24 Pieces) — $38.00

Snacks, soups, fruit, or larger meals—these Bayco Glass Food Storage Containers hold it all. This 24-piece set comes with four rectangular containers, four square containers, and four round containers of varying sizes, all of which are easy to clean thanks to the glass material. “I like that the seals in the lids come out, so you can easily clean what would be a tricky place to get otherwise,” says Reeder.

Safe with: dishwasher, oven, microwave, freezer

Pyrex, Glass Food Storage (6 Pieces) — $18.00

This six-piece glass food storage set will give you piece of mind during a busy week. Reeder recommends these containers because the lids don’t have any tiny or small areas that are difficult to clean, so you don’t have to worry about bacteria playing hide-and-seek whenever you’re hitting the sink. Featuring a two-cup, four-cup, and seven-cup containers, the set is ideal for meal prepping or stowing away leftovers so all of your yummy bites don’t go to waste.

It’s no secret that Pyrex makes some of the most durable, easy-to-clean containers, and this set is no exception to those standards.

DuraHome, Food Storage Containers (44 Pieces) — $23.00

If you’re not ready to commit to glass containers (which can be pricey), Reeder recommends this 44-piece set. “They are plastic; however, I love that they’re dishwasher safe and overall relatively easy to clean,” says Reeder. What’s inside? You’ll get 16 sets of eight-ounce containers, 16 sets of 16-ounce containers, 12 sets of 32-ounce containers, and lids that are interchangeable, so you can pack up soups, salads, condiments, fruit, snacks, meals, and more.
