Food safety management has traditionally relied on periodic sampling, laboratory analysis and expert inspection. Although these approaches remain indispensable, they are often slow, labour-intensive and limited in their ability to detect emerging risks across complex global supply chains. Artificial intelligence (AI) is increasingly being recognized as a tool that can transform the large and heterogeneous data generated in the food sector into timely, risk-based decisions.
A key strength of AI is its capacity to identify patterns in high-dimensional data that cannot easily be interpreted by conventional statistics. Data from spectroscopy, mass spectrometry, hyperspectral imaging, electronic noses and electronic tongues can be processed by machine learning and deep learning models to classify products, detect contamination and estimate quality parameters. In this way, rapid and non-destructive screening methods can be developed as complements to reference laboratory techniques.
Microbiological safety is one of the most relevant application areas. Predictive models have been developed to estimate microbial growth under varying temperature, pH and water activity conditions, and AI-based approaches are being used to forecast shelf life and spoilage. When combined with sensor data collected throughout storage and distribution, such models can support dynamic shelf-life labelling and reduce both health risks and food waste.
Chemical hazards are also being addressed. AI models have been applied to the detection of pesticide residues, mycotoxins, veterinary drug residues, heavy metals and processing contaminants, frequently in combination with spectroscopic data. In food fraud prevention, classification algorithms are being used to identify adulteration, species substitution and false geographical origin claims.
Beyond the laboratory, AI is being integrated into food safety management systems. Computer vision is being applied to the detection of foreign bodies and visual defects on processing lines and to the monitoring of hygiene practices. Natural language processing is being used to scan recall notices, regulatory alerts, scientific literature and news reports, enabling the early identification of emerging hazards. Combined with Internet of Things devices, these systems allow critical control points to be monitored continuously rather than intermittently.
Several limitations must nevertheless be considered. AI models depend heavily on the quality, size and representativeness of training data, and models trained under laboratory conditions may perform poorly in real production environments. Overfitting, a lack of external validation and limited interpretability can reduce confidence among regulators and industry. Explainable AI methods, standardized datasets, transparent reporting and rigorous validation against reference methods are therefore required. Data sharing between companies and authorities also raises questions of confidentiality and governance.
In conclusion, AI is not expected to replace established food safety systems such as HACCP, but to strengthen them by enabling faster detection, better prediction and more targeted control. Its successful implementation will depend on close cooperation between food scientists, data scientists, industry and regulatory bodies.
