What does food irradiation mean?

Food irradiation is a preservation method that entails subjecting food to ionizing radiation, such as gamma rays, X-rays, or accelerated electrons. The primary objective of this process is to diminish microbial presence, deactivate enzymes, and decelerate deterioration, ultimately prolonging the shelf life of the food and enhancing its safety for consumption.

In what way does this process impact the preservation and safety of food products?

Ionizing radiation has the capability to disrupt chemical bonds within molecules, effectively eliminating or deactivating pathogenic microorganisms like bacteria, viruses, and parasites. Furthermore, it contributes to a decline in the population of insects and larvae found in food. Additionally, irradiation plays a role in retarding the ripening process of fruits and vegetables, minimizing sprouting in tubers and bulbs, and mitigating the spoilage of various foods such as meat, fish, and dairy products.

What are the primary procedures and organizations overseeing the regulation of food irradiation in Brazil?

The oversight and control of food irradiation in Brazil fall under the purview of the National

Health Surveillance Agency (ANVISA). This regulatory body is tasked with formulating guidelines, standards, and regulations pertaining to food safety and quality in the country. Below, we outline the key steps involved in the regulation of food irradiation in Brazil:

Authorization for Use:

Prior to initiating any food irradiation activities, companies are required to secure authorization from the National Nuclear Energy Commission (CNEN) to operate irradiation equipment. CNEN is the regulatory body tasked with overseeing and regulating nuclear safety in Brazil.

Safety Standards:

ANVISA sets safety standards, dosage limits, and criteria for the application of irradiation in food. Complying with these standards is imperative for irradiated foods to guarantee their safety for consumption.


In accordance with Brazilian legislation, irradiated foods must bear clear and conspicuous labels, explicitly stating that they have undergone irradiation. This practice ensures that consumers receive transparent information regarding the food processing method.

Inspection and Oversight:

ANVISA and CNEN conduct routine inspections to verify adherence to regulations and ensure the safety of irradiated foods. This comprehensive assessment encompasses scrutiny of facilities, equipment, and records maintained by companies employing food irradiation.

Monitoring and Evaluation:

The regulatory agency actively monitors the safety of irradiated foods through rigorous analyses and studies, guaranteeing that products consistently meet established standards.

It is crucial to underscore that the regulation of food irradiation is designed to safeguard consumer safety and uphold the quality of irradiated foods. Companies seeking to employ irradiation as a method of food preservation must rigorously adhere to the regulations and standards established by competent authorities in Brazil.
