The FDA approves plastics for food contact that can withstand rigorous cleaning and sanitizing
The US Food and Drug Administration (FDA) has strict guidelines for plastics to be approved for food contact. A "food contact substance" (FCS) is defined as a substance that comes into contact with food without affecting it. This includes food packaging, processing equipment, and food preparation surfaces.
Several plastics have been approved by the FDA for food contact, including High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Polypropylene (PP). These plastics are commonly used in beverage bottles, food storage containers, and packaging materials. They have been deemed safe by the FDA due to their ability to resist chemicals, heat, and corrosion.
However, it is important to note that not all plastics are created equal, and some may pose health risks. Concerns have been raised about the presence of bisphenol A (BPA) in polycarbonate resin, and while the FDA has concluded that the intake of BPA from plastic is low and has no apparent negative health effects, there are ongoing petitions to restrict its use in food contact products. Additionally, experts caution that heat can break down chemical bonds in plastic, potentially increasing the rate of chemical migration into food. Therefore, it is crucial to follow the intended use and storage guidelines for plastic containers to ensure safety.
The FDA continues to closely monitor and evaluate the safety of plastics used for food contact. They maintain a public inventory of authorized food contact substances and provide scientific opinions on the use of recycled polymeric food contact materials to ensure consumer safety.

Plastic is a versatile material used in a variety of products, from food packaging to manufacturing equipment. While plastic containers are convenient for storing food, concerns have been raised about their safety, particularly when exposed to heat. The U.S. Food and Drug Administration (FDA) plays a crucial role in evaluating and regulating the safety of plastics that come into contact with food.
The FDA has specific guidelines for materials that directly contact food, ensuring they meet stringent safety standards. These "FDA-compliant" materials must withstand the intended use environment, such as high temperatures in an oven or the freezer. Several plastics have been approved by the FDA for food contact, including HDPE, LDPE, PP, and PET. These plastics are commonly used in beverage bottles, food storage containers, and packaging.
When it comes to using plastics in the freezer, microwave, and dishwasher, it is essential to follow the guidelines on the packaging. FDA-approved plastics can be safely used in these appliances when the package indicates they are suitable for such purposes. For example, some plastics are specifically designed to withstand high microwave temperatures and are labelled "Microwave Safe."
However, experts caution that heat can break down chemical bonds in plastic, potentially leading to chemical migration into food. This concern extends to containers labelled "safe" for the microwave and dishwasher, as the FDA's deference to manufacturers on "conditions of use" may not account for long-term wear and tear. While the FDA conducts rigorous testing, some experts question the rigor of their standards due to reliance on manufacturers' data.
To ensure safety, it is recommended to follow specific guidelines for food storage, temperature, and recycling. Additionally, alternatives to plastic containers, such as glass, stainless steel, and silicone, are worth considering as they are toxin-free and safe for use in the freezer, microwave, and dishwasher. While FDA-approved plastics are generally safe for use in the freezer, microwave, and dishwasher when indicated, staying informed about the latest research and expert recommendations is essential for making informed choices.

FDA-approved plastics include HDPE, LDPE, and PP
The US Food and Drug Administration (FDA) has strict guidelines for consumable items, and it closely examines the materials used in their production, including plastic. FDA-approved plastics include HDPE, LDPE, and PP, which are marked as safe for food contact and storage. These plastics are commonly used in our households and are generally very safe for food contact.
HDPE (High-Density Polyethylene) is the most common household plastic. It is used to make beverage bottles, butter containers, cereal box liners, and thicker food storage buckets. Recycled HDPE is reviewed by the FDA on a case-by-case basis as it can become unsafe during the recycling process. HDPE is marked with resin identification code 2 and is known for its durability and lightweight feel. It is also easy to clean and resistant to corrosion.
LDPE (Low-Density Polyethylene) is similar to HDPE but is less rigid, making it ideal for squeeze bottles, plastic film, and flexible packaging. LDPE is chemically resistant, repels microorganisms, and does not leach harmful toxins when used for food storage. It is marked with resin identification code 4 and is easily reusable, although it is not deemed safe for food contact when recycled.
PP (Polypropylene) is a plastic that is generally used for single-serve items like yogurt cups and cream cheese containers. It has a high melting point, making it safe for use in the microwave and dishwasher. PP is marked with resin identification code 5 and is lightweight, flexible, and durable. It is also microwave-safe and non-volatile, meaning it won't react with any type of food stored in it.
