The question of using Sterilite containers for food storage often arises because people naturally seek convenient and cost-effective solutions for storing leftovers, meal prepping, and organizing pantries. While Sterilite containers are ideal for storing a variety of non-food items, it’s crucial to understand the specific types of plastic used in their construction and whether they are designed to come into direct contact with food. The company utilizes primarily two types of plastic in their containers: Polypropylene (PP) and Polyethylene (PE). You can usually find the recycling symbol, containing a number, on the bottom of the container to identify the type of plastic used. Knowing this is crucial because it tells you more about its properties.
Polypropylene, often identified by the recycling symbol number five, is a versatile thermoplastic polymer known for its high heat resistance and chemical resistance. Polyethylene, commonly identified by the recycling symbols number two (HDPE – High-Density Polyethylene) or number four (LDPE – Low-Density Polyethylene), is another widely used thermoplastic known for its flexibility and durability. While these plastics offer numerous benefits for storage purposes, understanding their suitability for food storage is essential.
Sterilite’s Stance on Food Storage
To determine the food safety of Sterilite containers, it’s crucial to examine the manufacturer’s official stance. Sterilite’s website and product documentation provide valuable insights into their intended uses and any disclaimers related to food storage. It’s important to note that while some Sterilite containers may be marketed as suitable for general storage, not all are specifically designed or certified for direct food contact. Careful examination of product labels and descriptions is essential to avoid misusing these containers for purposes they were not intended.
The term “food-safe” refers to materials and products that are safe for contact with food. Food-safe materials are designed to prevent the migration of harmful chemicals into the food and meet specific regulatory standards. This definition ensures that consumers can confidently use these products without risking contamination or health hazards. Regulatory bodies, such as the Food and Drug Administration (FDA), set standards for food-safe materials, ensuring that they do not pose a risk to public health.
This brings us to the importance of “food-grade” plastic. Food-grade plastic is a specific type of plastic that meets the requirements of these regulating bodies and is deemed safe for contact with food. Food-grade plastics are manufactured under strict guidelines to ensure that they do not contain harmful chemicals or substances that could leach into the food. These plastics are also designed to withstand various conditions, such as temperature changes and exposure to acidic or alkaline substances, without degrading or releasing harmful chemicals. The FDA regulates the use of food-grade plastics in the United States, setting stringent standards for their composition and manufacturing processes. These regulations ensure that food-grade plastics are safe for direct contact with food and do not pose a risk to public health.
Risks of Using Non-Food-Grade Containers for Food
Using non-food-grade containers for food storage carries several potential risks. One of the primary concerns is chemical leaching, which occurs when chemicals from the plastic migrate into the food. This process can be accelerated by factors such as temperature, acidity, and exposure to certain substances. Even if a plastic is considered generally safe at room temperature, heating it in the microwave or dishwasher can increase the likelihood of chemical leaching.
While Sterilite claims that their containers are BPA-free and phthalate-free, the potential for leaching from other chemicals in the plastic remains a consideration. Exposure to these chemicals can have various health effects, ranging from endocrine disruption to potential developmental issues. While the levels of these chemicals may be low, prolonged exposure can pose a risk, especially for vulnerable populations such as children and pregnant women.
Beyond chemical leaching, non-food-grade plastics can be porous, meaning that they have small openings or spaces that can harbor bacteria. Even after washing, bacteria can persist in these pores, leading to potential food contamination. This is especially concerning for foods that are prone to spoilage or those that support bacterial growth. Using non-food-grade containers for storing food can also lead to cross-contamination, where harmful bacteria or allergens from one food item transfer to another.
Assessing Sterilite Containers for Food Storage Suitability
If you’re considering using Sterilite containers for food storage, there are several steps you can take to assess their suitability. First, identify the plastic type by locating the recycling symbol on the container. As mentioned, polypropylene (PP) and polyethylene (PE) are common plastics used by Sterilite. Polypropylene is generally considered a safer option for food storage compared to some other plastics, but it’s still essential to use it with caution and consider the intended use.
Next, perform a visual inspection of the container. Check for any signs of damage, such as cracks, scratches, or discoloration. Damaged containers are more likely to leach chemicals and harbor bacteria, making them unsuitable for food storage. Also, look for any staining or residue on the container. Staining can indicate that the container has absorbed substances from previous contents, potentially affecting the safety of any food stored in it.
Another helpful step is to perform a smell test. Sniff the container and check for any unusual or chemical odors. A strong chemical odor can indicate that the plastic is degrading or leaching chemicals, making it unsuitable for food storage. A clean, odorless container is generally a better option for storing food.
Finally, consider the intended use of the container. Sterilite containers come in various shapes and sizes, each designed for specific storage purposes. Ensure that the container you’re using is appropriate for the type of food you plan to store. For instance, using a container designed for dry goods to store liquid or acidic foods can increase the risk of chemical leaching and spoilage.
Best Practices for Using Sterilite Containers (If You Choose To)
If you decide to use Sterilite containers for food storage, following certain best practices can help minimize potential risks. First, consider the types of food you’re storing. Dry goods, such as grains, pasta, and cereals, are generally considered safer to store in Sterilite containers compared to highly acidic or fatty foods. Acidic foods, such as tomatoes and citrus fruits, can accelerate chemical leaching from the plastic, while fatty foods can absorb chemicals from the plastic, affecting the taste and safety of the food.
Avoid storing hot foods in Sterilite containers. Heat can accelerate chemical leaching and damage the plastic. Allow hot foods to cool completely before transferring them to the container. When washing Sterilite containers, follow the manufacturer’s recommendations. Some containers may be dishwasher safe, while others may require handwashing.
