5 Ways To Ensure Food Safety When Using Plastic Containers

A plastic container with a lid and other design features is among the most popular solutions for packaging and storing food used by many households and businesses around the world. Not only are they convenient to use, but plastic containers are also very accessible and affordable. As such, a lot of kitchens are well stocked with plastic containers when it comes to food packaging and storage.

However, because food spoils and can bring a number of food-borne illnesses, it is important for homeowners and business owners alike to handle and store food as safely as possible. Read on to find out some of the most effective ways to ensure food safety, specifically whenever you are using a plastic container box for food.

1. Utilise food-grade plastic containers

A food-grade plastic container is basically one that does not transmit non-food chemicals into food. According to food safety experts, the use of non-food-grade plastic containers increases the chances of contamination in food. As such, it is necessary to always use food-grade plastic containers when storing food. Plastic containers should follow specific regulations to ensure that they are safe for food.

2. Make use of single-use containers only once

Small disposable containers that are intended for single use must be used only once. As a material, plastic deteriorates over time. Some plastic items are not designed to endure cooling and heating. Most plastics that have a recycling code number “one” are often created for single use. Rather than using these plastics multiple times, you should transfer your food to other containers that are specifically intended for reheating meals.

3. Use proper food containers for the microwave

If your food is meant to be reheated, it is highly advised to package or store it in plastic containers that are specifically manufactured for microwave use. Certain types of plastics are safe for the microwave, if they are labelled as “microwave safe.” Experts advise against microwaving disposable containers that are not designed for this purpose, as this can lead to accidents, such as fires and explosions.

4. Freeze food only in plastic containers intended for the freezer

Similarly, if your food is intended to be placed inside the freezer, you should put it in a container that has a freezer-safe label. Plastics should only be placed in the freezer if they have this label. Other disposable containers, such as milk or ice cream cartons, must be avoided for freezer use. As much as possible, you should only use containers in the freezer that are leak-proof, easy to seal, and moisture-vapour resistant.

5. Wash plastic food containers by hand

Although certain plastics are safe to be put into the dishwasher, it is usually recommended to wash plastic food containers by hand. In doing so, you can ensure that those grooves around the container’s openings are clean so that no pathogen contaminates other food.


Safety is one of the most important aspects of handling and storing food. To prevent the development of food-borne illnesses and keep your food safe, it is necessary to follow the safety precautions mentioned in this article, specifically if you are using plastic food containers. Indeed, food spoils easily, and keeping it safe to eat and free from contamination is a huge responsibility to bear.
