Updated by SFA Commercial plastic packaging that has been used for storing non-food items (e.g. detergents) should never be reused as food containers. They have not been tested safe for food storage and they may contain non-food residues that contaminate food.
Plastic packaging that are used for commercial packing of food and takeaway plastic food containers used in eating outlets are disposable items designed for single use and are not intended for repeated storage of food. They are safe for their immediate intended purpose but not beyond what they are designed for.
Plastic packaging for microwaveable convenience meals are designed for one-time usage with the type of food packed in it and should not be reused for storing or microwave heating of food.
Only use reusable plastic food containers (e.g., cups, plates, bowls, bottles and boxes that can be purchased at the kitchenware section in retail stores) for repeated storage of food. These containers have the sturdiness, thermal stability and other attributes needed for a reusable food container.
Reusable plastic food containers can be subjected to wear and tear over a period of use. They should be replaced when they have turned cloudy or discoloured or if cracks or heavy abrasions start to appear.
See our Food Safety Tips for more information on safe food practices.
