Meta-Analysis on Foodborne Pathogens in Animal-Derived Foodstuffs in Maghreb Countries

Animal-derived foodstuffs are essential for human nutrition but may harbor pathogens responsible for foodborne diseases. In Maghreb countries (Algeria, Libya, Morocco, and Tunisia), data on foodborne pathogen hazards are often limited and fragmented. To address this gap, the present systematic review and meta-analysis aimed to estimate the overall prevalence of foodborne pathogens in animal-derived foods in the Maghreb region from 2004 to 2025. A systematic literature search was conducted in two electronic databases (PubMed and Scopus) following PRISMA guidelines. A total of 80 studies met the inclusion criteria. Data were analyzed using the meta package in R software, applying a random-effects model. The pooled prevalence of pathogens in foods of animal origin was 26.6% (95% CI: 20.0–33.8), with high heterogeneity ( I ² = 98.9%). The highest contamination was observed in raw poultry meat (36.1%). Eleven foodborne bacterial species were reported. Salmonella spp. was the most frequently reported ( n = 18), with a pooled prevalence of 14.2%, followed by Staphylococcus aureus (28.3%, n = 16) and Escherichia coli (36%, n = 16). Most studies were conducted in Algeria and Morocco, with country-level prevalence ranging from 22.1% to 38.1%. This review reveals a substantial burden of foodborne pathogens in the Maghreb region. Enhanced surveillance and targeted control measures are essential to improve food safety and protect public health.
