CHEFS – The New Unified Database for Food Safety in Europe

2026-02-06

How the EU Transforms EFSA Data into Opportunities for Artificial Intelligence and Effective Public Policies

In the European Union, official food safety monitoring data collected annually by Member States are submitted to the European Food Safety Authority (EFSA) and published on the Zenodo platform. The volume of this information is remarkable: more than 392 million analytical results derived from 15.2 million samples, covering over 4,000 types of food products.

This massive dataset presents exceptional opportunities for applying artificial intelligence to identify trends, predict hazards, and develop early warning systems. However, its current format—distributed across roughly 1,000 files totaling several hundred gigabytes—limits accessibility and analytical efficiency.


CHEFS: the solution for centralizing monitoring data

To overcome these barriers, researchers have created the CompreHensive European Food Safety (CHEFS) database— a unified resource integrating all EFSA monitoring data on:

  • pesticide residues
  • residues of veterinary medicinal products
  • chemical contaminants

 

CHEFS consolidates a fragmented mass of information into a coherent, structured, and accessible dataset, optimized for research, public policy analysis, and machine-learning applications.


How the CHEFS database was built

The team behind the database describes in detail the processes of:

  • aggregating data from all Member State submissions
  • cleaning and standardizing the information to remove errors and inconsistencies
  • harmonizing product codes, contaminants, and analytical methods
  • integrating everything into a single logical architecture designed for advanced analysis

The result is a robust, scalable resource, ready for use in research regardless of the user’s technical background.

 

What the data reveal: analysis of the 2000–2024 period

Using the CHEFS database, the authors examined how food safety monitoring has evolved in Europe over nearly 25 years. Their analyses explore:

  • Changes in monitoring activities

How frequently and intensively Member States have tested food products over the years, based on emerging risks.

  • The most frequently tested food products

Which categories are considered high-risk and consistently monitored.

  • Products with the highest non-compliance rates

Identifying food categories that most often exceeded legal limits.

  • The contaminants most commonly detected

Recurrent problematic substances found in the European food chain.

  • Differences between countries

Variations in controls, contamination rates, and monitoring practices at national level.

 

CHEFS – a strategic tool for the future of food safety

The study’s conclusions clearly show that CHEFS is not merely a centralized data repository, but a strategic tool capable of:

  • guiding European public policies
  • supporting regulatory decision-making
  • strengthening academic research
  • improving the EU’s ability to detect emerging risks
  • accelerating the use of artificial intelligence in food safety
