Cross-contamination risks and hazard analysis and critical control point (HACCP) strategies in the meat industry: A Review

Abstract

The meat industry plays a vital role in supplying animal protein; however, it also carries a high risk of cross-contamination, which poses a significant threat to food safety. Cross-contamination can occur at multiple stages of the production chain, including slaughtering, cutting, processing, storage, and distribution, with primary sources stemming from infected animals, contaminated equipment, workers, and the surrounding environment. The consequences include a higher incidence of foodborne diseases, substantial economic losses due to product recalls, and a decline in consumer confidence. To mitigate these hazards, the Hazard Analysis and Critical Control Points (HACCP) system is internationally recognized as a science-based and preventive approach. This review discusses the fundamental principles of HACCP, including hazard identification, determination of Critical Control Points (CCP), and the mechanisms of monitoring, verification, and documentation. Furthermore, it explores HACCP implementation across various meat commodities (beef, poultry, pork), highlights differences in application between developed and developing countries, and examines key factors influencing its effectiveness, such as regulatory frameworks, worker training, and the availability of production facilities. Despite persistent challenges—such as implementation costs, limited human resources, and low hygiene awareness technological advancements, including IoT-based sensors, rapid detection methods, and blockchain traceability, offer promising opportunities to strengthen HACCP systems. Integration with other standards (ISO 22000, GMP, SOP) and the move toward a digitalized, smart meat processing industry further reinforces HACCP as a pivotal strategy to ensure food safety and enhance the global competitiveness of the meat industry.
