What You'll Learn
Check the recycling number on the bottom
When buying plastic containers, it is important to check the recycling number on the bottom. These numbers range from 1 to 7 and indicate the type of plastic resin used, with some being safer for food storage than others. Plastic containers with recycling numbers 2, 4, and 5 are generally considered safe for food storage. Number 2 plastics are typically made from high-density polyethylene (HDPE), which is resistant to mould, mildew, and corrosion, making it safe for food storage. Number 4 plastics are often made from low-density polyethylene (LDPE) and are commonly used for bread bags, six-pack rings, and produce bags. Number 5 plastics are usually made from polypropylene (PP) and are known for their strength and stability.
On the other hand, it is best to avoid plastic containers with recycling number 3. These plastics are often made from polyvinyl chloride (PVC), which can contain harmful chemicals such as phthalates. Number 7 plastics should also be avoided as they are often made from polycarbonate, which can release bisphenol A (BPA) into food and beverages. BPA is a known endocrine disruptor and has potential links to health issues.
It is worth noting that while plastic containers with recycling number 1 are not recommended for food storage, they can still be used for other purposes. Number 1 plastics are typically designed for single-use and are not meant to withstand repeated heating and cooling. Number 6 plastics, made from polystyrene, can be used for non-food items or for short-term food contact if they are marked as food-safe. Number 7 plastics may be safe if they are specifically marked as food-grade, but it is generally recommended to choose an alternative option if possible.
Checking the recycling number on the bottom of plastic containers is a crucial step in ensuring the safety of the products you purchase. By choosing containers with the safest recycling numbers, you can reduce the risk of toxic chemical exposure and make a more informed decision about the products you bring into your home.

Avoid single-use plastics
Plastic is widely used for storing food, but it often contains harmful chemicals such as BPAs, which are unsafe for human consumption and can lead to health problems. Plastic containers with grades 2, 4, and 5 are considered the safest for food storage, preventing accidental toxin ingestion. These include HDPE, LDPE, and PP plastics, which are marked as green on the safe plastic numbers chart.
To avoid single-use plastics, it is recommended to switch to glass, ceramic, or metal containers whenever possible. Single-use plastics, such as water bottles, food wrappers, to-go packaging, and plastic bags, contribute significantly to pollution and the accumulation of waste. By choosing reusable alternatives, you can reduce your environmental impact.
When purchasing food, consider buying in bulk or from bulk aisles to reduce the amount of single-use plastic packaging. You can also refuse plastic utensils and straws when ordering food to-go and bring your own reusable containers instead. Additionally, carrying a reusable water bottle made from metal or glass can help you avoid single-use plastic water bottles.
It is important to avoid scratched, discolored, or expired plastic containers, as they may release chemicals into your food or drink. Oily and fatty foods should also not be stored in plastic containers, as many chemicals in plastic are fat-soluble and can leach into these foods. Always check the bottom of containers for the food-grade rating to ensure it is safe for food storage.
By following these guidelines, you can significantly reduce your consumption of single-use plastics and contribute to a greener and healthier planet.

Avoid heat and scratches
Plastic is widely used for storing food, but it has been found to contain harmful chemicals, such as BPAs, which are unsafe for human consumption. These chemicals can migrate into our bodies and the food chain, causing unknown health issues.
When buying plastic containers, it is important to look out for signs that indicate the product may not be suitable for use with food. Avoid scratched plastic containers, as scratches can be a sign of wear and tear, and increase the likelihood of chemicals leaching into food. Scratches can also be hard to clean, leading to a build-up of bacteria.
It is also important to avoid heat when using plastic containers. Heating plastic can cause it to break down, allowing unknown chemicals to leach into food and drink. This includes heating in the microwave and dishwasher, as well as exposure to sunlight. Oily foods are also thought to attract some plastic chemicals, so these should be avoided.
To avoid scratches, it is important to clean plastic containers regularly. This will prevent a build-up of dust and debris, which can lead to deeper scratches over time. When washing plastic containers, be aware of any lids that no longer seal well, or containers that have become scratched, cracked, or misshapen. These containers should be replaced.

Avoid storing fatty foods
Plastic containers are a common and convenient way to store food. However, there are some things to look out for when buying and using plastic containers, especially if you want to avoid storing fatty foods.
Firstly, it is important to understand that not all plastics are created equal. Some types of plastic are more suitable for food storage than others. When buying plastic containers, look for those made from polypropylene or polyethylene, or a mix of both. These plastics generally don't contain BPA or phthalates, which are known to be harmful. You can identify the type of plastic by looking for the resin identification code on the bottom of the container, usually a triangle with a number from one to seven inside. The safest choices for food storage are numbers one, two, four, and five.
Secondly, it is crucial to avoid storing fatty foods in plastic containers. Fatty foods, such as lasagna, butter, cheese, and meat, can absorb more chemicals from plastic containers compared to other types of food. This is because many of the chemicals used in plastic are fat-soluble and are, therefore, more likely to leach into fatty foods. Over time, fatty foods can also break down the plastic, increasing the risk of food contamination.
Thirdly, heat is a significant factor to consider when using plastic containers. Never store hot food or liquids in plastic containers, as the high temperatures can cause the plastic to release harmful chemicals. This includes reheating food in the microwave, as microwaving food in plastic containers can accelerate plastic degradation and increase the release of microplastics and chemical additives into your food. Always allow food to cool before storing it in plastic containers and opt for glass or ceramic containers for hot food.
Lastly, it is important to consider the potential for cross-contamination when storing fatty foods. Fatty foods can come into contact with other foods, such as acidic or salty foods, which can increase the likelihood of chemical leaching. For example, if you store leftover lasagna, which contains fatty, acidic, and salty components, in a plastic container, the complex mixture can increase the release of chemicals, especially when reheated or stored for extended periods.
In summary, while plastic containers are convenient, they may not be the best choice for storing fatty foods. Look for containers made from polypropylene or polyethylene, avoid storing hot food or liquids, and be mindful of the potential for cross-contamination with other types of food. To be extra cautious, you may consider opting for glass or ceramic containers, especially for fatty foods.

Check for food-grade rating
When buying plastic containers, it is important to check for their food-grade rating to ensure the containers are safe for food storage and consumption. Food-grade plastic containers are those that will not transfer non-food chemicals into the food. Non-food grade containers may contaminate food with toxins and chemicals, which can cause serious health issues.
Food-grade plastic containers are marked with a recycling number on the bottom, ranging from 1 to 7. The numbers indicate the type of plastic and how safe it is for food storage. Safe plastic numbers include 2, 4, and 5, which are marked in green on the label. These plastics can be used for food storage without the risk of toxic chemicals infiltrating the food. The materials with these ratings include HDPE, LDPE, and PP.
Plastics with a rating of 1 are generally intended for single use only and should not be reused, as they can become unsafe and leak toxins. Some sources also advise avoiding plastics with a rating of 3 and 6, as these may contain harmful chemicals. Plastics with a rating of 7 are bioplastics, which are non-reactive and safe for food storage.
It is important to note that food-grade does not always mean food-safe. Food-grade materials are only considered food-safe if they are used as intended. For example, a plastic container meant for dry food may not be safe for storing hot liquids, as the heat can break down the chemical bonds of the plastic, causing toxins to contaminate the food. Therefore, it is crucial to follow the intended use instructions for food-grade containers to ensure food safety.
