Food safety in school canteens: what can we learn from the case of Lleida?

The recent appearance of maggots in school canteen rations at the Lestonnac school in Lleida has generated concern among families and has highlighted the importance of maintaining high food safety standards in schools. This incident, which comes in addition to a previous case at the same school, underlines the need for constant vigilance and effective protocols to ensure the health of students.

The case of Lleida: a wake-up call

In January 2025, small worms were detected in some portions of lentils, rice and vegetables served in the canteen of the Lestonnac school. This finding occurred just over two months after worms, possibly anisakis, were found in fresh fish fillets at the same center. Although health authorities did not identify serious health risks in either case, the recurrence of these incidents has raised concerns among families and has led the school’s management to consider a change in the company in charge of the canteen service.

Importance of food safety in school environments

School canteens play a crucial role in the nutrition and well-being of students. Therefore, it is essential that suppliers and schools implement strict quality control and food safety measures. These include:

• Careful selection of suppliers: Ensure that food comes from reliable sources and complies with current health regulations.
• Adequate food maintenance: Ensure optimal storage and preparation conditions to prevent the proliferation of microorganisms or parasites.
• Staff training: Train the food handling team in hygienic practices and safety protocols.
• Transparent communication: Timely and clear reporting of any incidents related to food security to households.

The incidents that occurred at the Lestonnac school in Lleida highlight the importance of maintaining constant vigilance and implementing preventive measures to ensure the quality of food in school canteens. Food safety is not only the responsibility of the supplying companies, but also of the schools, health authorities and families. In this joint effort, technologies such as Tedepad’ s play a fundamental role, making it possible to treat fish viscera before returning them to the sea, thus reducing the proliferation of parasites such as anisakis in the food chain. By working together, from source to plate, we can ensure that students receive safe and nutritious food that contributes to their development and well-being.
