Regulatory framework for food irradiation
Food irradiation is a process that exposes food to a controlled amount of ionizing radiation, with the aim of reducing the risk of foodborne illnesses and increasing the shelf life of food. In order to ensure the safety and effectiveness of food irradiation, regulatory frameworks have been put in place to govern the process. These frameworks set standards for the use of irradiation on food, and also prescribe which foods are permitted to be irradiated.
- In the United States, the regulatory body responsible for overseeing food irradiation is the Food and Drug Administration (FDA). The FDA established the regulatory framework for food irradiation in 1980, and the framework is updated regularly through a public notice and comment process.
- The European Union has its own regulatory framework, which is governed by European Union regulations. The regulations specify, among other things, which foods are permitted to be irradiated, and also set maximum doses of irradiation for each type of food.
- Other countries, such as Canada and Australia, also have their own regulatory frameworks for food irradiation, which are similar to those in the United States and the European Union.
In addition to regulations governing the use of irradiation on food, there are also regulations for labeling irradiated food. In the United States, for example, irradiated food must bear the Radura symbol, which is a green flower with a broken circle around it, along with the statement “Treated with radiation” or “Treated by irradiation”.
The following table provides an overview of the regulatory frameworks for food irradiation in the United States, the European Union, Canada and Australia:
| Country | Regulatory Body | Foods Permitted to be Irradiated | Maximum Doses of Irradiation |
|---|---|---|---|
| United States | Food and Drug Administration (FDA) | Fruits, vegetables, poultry, red meat, spices, molluscan shellfish, some seafood | Up to 4.0 kiloGray (kGy) for fresh fruits and vegetables, up to 7.0 kGy for poultry and red meat, up to 30.0 kGy for spices |
| European Union | European Union regulations | Fruits, vegetables, cereals, poultry, red meat, fish, some seafood, herbs and spices | Up to 1.0 kGy for fruits and vegetables, up to 3.0 kGy for poultry, red meat, and some seafood |
| Canada | Canadian Food Inspection Agency (CFIA) | Fruits, vegetables, poultry, red meat, and some seafood | Up to 7.0 kGy for fresh fruits and vegetables, up to 10.0 kGy for poultry and red meat |
| Australia | Food Standards Australia New Zealand (FSANZ) | Fruits, vegetables, poultry, red meat, some seafood, herbs and spices | Up to 1.0 kGy for fruits and vegetables, up to 10.0 kGy for poultry and red meat |

Some critics argue that the long-term effects of consuming irradiated food are not fully understood, and others claim that irradiation can cause harmful chemical changes in food. However, supporters of food irradiation argue that it is a safe, effective way to reduce the risk of foodborne illnesses, and point to the fact that over 50 countries have approved the use of irradiation on food.
Irradiated vs non-irradiated food shelf life comparison
One of the main advantages of irradiation is that it can extend the shelf life of food. Here is a comparison of shelf lives between irradiated and non-irradiated food:
- Irradiated beef can last up to 4 weeks longer than non-irradiated beef
- Irradiated strawberries can last up to 7 days longer than non-irradiated strawberries
- Irradiated spices can last up to 3 years longer than non-irradiated spices
This extended shelf life can be attributed to the fact that irradiation reduces the number of bacteria and other microorganisms that can spoil food. By reducing the microbial load, irradiation can slow down the rate of spoilage, which in turn can extend the shelf life of food.
It is important to note that irradiation does not make food completely sterile. Some microorganisms can still survive the irradiation process, especially those that form spores. However, even with these surviving microorganisms, the overall microbial load is still significantly reduced.
| Food Item | Shelf Life of Non-Irradiated Food | Shelf Life of Irradiated Food |
|---|---|---|
| Beef | 3-5 days | up to 4 weeks longer than non-irradiated beef |
| Strawberries | 3-7 days | up to 7 days longer than non-irradiated strawberries |
| Spices | 2-3 years | up to 3 years longer than non-irradiated spices |
In conclusion, irradiation can significantly extend the shelf life of food by reducing the microbial load and slowing down the spoilage process. While some microorganisms may still survive the irradiation process, the overall reduction of spoilage is a crucial factor in maintaining the safety and quality of food.
