What do public health organizations say about polystyrene foodservice packaging?
Public health officials encourage the use of sanitary, single-use foodservice packaging (such as polystyrene) in appropriate settings. Single-use foodservice packaging can help reduce food-borne illness in homes, hospitals, schools, nursing homes, cafeterias and restaurants.

What do regulatory agencies say about the safety of polystyrene foodservice packaging?
In the United States, FDA strictly regulates all food packaging materials, including polystyrene. FDA has for decades stated that polystyrene is safe for use in contact with food. The European Commission/European Food Safety Authority and other regulatory agencies have reached similar conclusions.
What do scientific experts say about the safety of polystyrene foodservice packaging?
From 1999 to 2002, a 12-member international expert panel selected by the Harvard Center for Risk Analysis conducted a comprehensive review of potential health risks associated with workplace and environmental exposure to styrene.
The scientists reviewed all of the published data on the quantity of styrene contributed to the diet due to migration from food contact packaging. The scientists concluded that there is no cause for concern from exposure to styrene from food or from polystyrene used in food contact applications, such as packaging and foodservice containers.
Is it common for substances from packaging to “migrate” into food?
All packaging – glass, aluminum, paper and plastics (such as polystyrene) – contains substances that can “migrate” in very tiny amounts to foods or beverages. That’s one of the reasons why FDA regulates food packaging in the first place – to be confident that the amount of substances that might actually migrate is safe.
Test data submitted to FDA indicated that the migration of styrene from polystyrene foodservice products is tiny and expected to be significantly below the safety limits set by FDA itself – 10,000 times less than FDA’s acceptable daily intake level.
Where does styrene come from?
Styrene occurs naturally in many foods and beverages. Its chemical structure is similar to cinnamic aldehyde, the chemical component that creates cinnamon’s flavor. Styrene also is manufactured as a building block for materials used to make automobiles, electronics, boats, recreational vehicles, toys and countless other consumer products.
How can people come into contact with styrene?
People can come into contact with styrene from the small amounts that may be present in air (primarily from automobile exhaust and cigarette smoke) and in foods and packaging. Styrene is naturally present in many foods, such as cinnamon, beef, coffee beans, peanuts, wheat, oats, strawberries and peaches. In addition, FDA has approved styrene as a food additive – it can be added in small amounts to baked goods, frozen dairy products, candy, gelatins, puddings and other food.
What is Styrofoam made of?
Many people incorrectly use the name STYROFOAM® to refer to polystyrene in food service; STYROFOAM® is a registered trademark of The Dow Chemical Company that refers to its branded building material products.
What are styrene uses?
For more than 70 years, styrene has been used as a chemical building block to make the materials used in a wide variety of finished consumer products, such as food containers, rubber tires, building insulation, carpet backing and boat hulls, surfboards, residential kitchen countertops, bathtubs and shower enclosures.
What is the difference between styrene and polystyrene?
The difference is chemistry. Styrene is a liquid that can be chemically linked to create polystyrene, a solid plastic that displays different properties. Polystyrene is used to make a variety of consumer products, such as foodservice containers, cushioning for shipping delicate electronics and insulation.
What is extruded polystyrene foam?
Extruded polystyrene (XPS) foam is a rigid insulation that has also formed with polystyrene polymer, but manufactured using an extrusion process. This type of insulation can significantly reduce a building’s energy use and help control indoor temperature.
