AI
Potential in Food Safety
The global food safety and quality assurance systems are undergoing rapid development due to the adoption of AI. The adoption of AI in food safety and quality assurance is accelerating, sensor-enabled packaging and AI-assisted “tongues” are at the cusp of commercialization and the patents have been filed for novel sensor arrays and RFID-integrated labels, and market reports predict growth in chemical sensors and smart packaging as well as tools like Elsa by FDA setting new benchmarks for regulatory efficiency.
Global initiatives utilizing deep learning, explainable AI, and smart sensors point toward a future where food safety systems are proactive, transparent, and deeply integrated across the supply chains. Combining these technologies could yield new business models or services where consumers soon will be able to scan packages to get personalized freshness data, or manufacturers offering “shelf-life guarantees” based on sensor feedback, but continued investment in research, regulation, and interdisciplinary collaboration will be essential to ensure these technologies fulfill their promise.
In 2025, the U.S. Food and Drug Administration (FDA) launched "Elsa," an AI-powered assistant developed to enhance its inspection and recall processes. Elsa is emblematic of a broader shift toward AI-enhanced food safety, joined by parallel innovations such as machine learning models trained on RASFF data in Europe, Vision Transformers for visual inspection, and smart packaging with integrated sensors.
The FDA’s AI Tool Elsa
Elsa (an acronym for "Evaluation of Labeling and Safety Assistant") was introduced by the FDA to support staff in analyzing safety reports, identifying inconsistencies in product labels, and prioritizing inspections. Using natural language processing (NLP) and supervised learning models, Elsa can parse thousands of incident reports, cross-reference product attributes, and highlight anomalies in labeling that may signal misbranding or undeclared allergens.
Elsa's primary capabilities include:
Label validation: Cross-referencing product descriptions with regulated allergen and ingredient databases.
Adverse event triage: Analyzing safety reports to flag high-risk incidents for further inspection.
Recall prioritization: Scoring and ranking product risks based on historical recall data and current trends.
According
to the FDA (2025), early internal testing of Elsa reduced report analysis time
by up to 40% and improved recall response speed by 25%.
Design,
Architecture, and Use Cases
Elsa's architecture follows a modular, service-oriented design using cloud infrastructure.
The key components include:
- Natural Language Processing Engine: Built on Transformer-based models (e.g., BERT fine-tuned for regulatory data) to extract entities, context, and sentiment from consumer complaints, safety reports, and product labels.
- Knowledge Graph: A dynamically updating ontology that links ingredients, allergens, product categories, and regulatory codes (such as 21 CFR parts) to support contextual inferences and compliance verification.
- Machine Learning Classifiers: Supervised models trained on historical recall and labeling error datasets. These models predict the severity and priority of new cases.
- Recommendation Engine: Uses rule-based heuristics and ML-predicted risk scores to assign follow-up actions to human inspectors.
- User Interface: A secure FDA dashboard for internal analysts to review Elsa's outputs, risk justifications, and cross-reference findings with external databases like FARS (Food Adverse Reaction System).
Data
Sources Elsa
ingests and processes data from:
- Adverse Event Reporting Systems
- Industry-submitted recall documentation
- Third-party food traceability platforms
- FDA Label Archive and ingredient records
Use
Cases in Practice
Label Verification: Elsa scans nutritional and ingredient labels against FDA regulations to detect omissions, undeclared allergens, or inconsistencies in font, format, and disclaimers.
Incident Prioritization: When a batch of complaints is received, Elsa clusters them, identifies outliers or spike patterns, and recommends inspections.
Recall Simulation: Elsa supports scenario-based analysis to estimate the impact of potential recalls based on product volume, distribution region, and consumer demographics.
During
its beta deployment in late 2024, Elsa assisted in identifying 14 undeclared
allergen violations in prepackaged food products and reduced the median report
review time from 18 hours to under 6 hours per case.
Further, the Rapid Alert System for Food
and Feed (RASFF) of Europe provides a rich dataset for training AI models,
where researchers from the University of Portsmouth (2024) developed an
integrated framework using machine learning (ML), deep learning (DL), and
Transformer-based architectures to identify contamination trends. Explainable
AI (XAI) modules such as SHAP (SHapley Additive exPlanations) were incorporated
to improve model interpretability.
This
framework allows regulators to:
Predict high-risk shipments
based on product type, origin, and historical violations.
Allocate inspection resources
more efficiently.
Communicate findings in
human-understandable formats.
Hyperspectral
Imaging and Vision Transformers
A recent
study (Kim et al., 2025) demonstrated the use of hyperspectral imaging (HSI)
paired with Vision Transformer (ViT) networks for detecting foreign materials
in pork belly processing lines. Unlike traditional CNNs, ViTs can capture
long-range spatial dependencies and offer better generalization in noisy
industrial environments.
This system
achieved a detection accuracy of 96.4% and operates in real-time, offering
manufacturers an automated, non-invasive alternative to manual inspection.

Regulatory and Ethical Considerations
AI systems in food safety raise questions around transparency, accountability, and data governance. While tools like Elsa offer efficiency, they must be audited regularly to avoid reinforcing data biases. Similarly, predictive models must ensure fairness across different product categories and geographical sources.
Regulatory frameworks must evolve to:
Define AI validation standards.
- Mandate periodic audits and updates.
- Ensure explainability and traceability of decisions.
Challenges
and Future Directions
Despite
their promise, AI tools face several challenges:
- Data quality: Inconsistent or sparse data can degrade model performance.
- Interoperability: Integrating AI systems with legacy food safety infrastructure.
- Human-AI collaboration: Ensuring AI augments, not replaces, expert judgment.
Future
directions include:
- Expansion of AI-generated SOPs and HACCP plans (e.g., FoodReady platform).
- Broader deployment of AI in developing countries.
- Increased use of synthetic data to train robust models under rare contamination scenarios.
