Abstract
Food-borne Toxoplasma gondii infection is ranked among parasitic diseases of global concern. Toxoplasmosis is qualified as a one health disease, since it affects human health, animals, and ecosystems. The present study was performed to estimate the molecular prevalence of T. gondii in industrial poultry meat samples from Tunisia. A total of 140 breast samples were collected from chicken (Gallus gallus domesticus) and turkey (Meleagris gallopavo) and four breeding systems (broiler chickens, reform laying hens, chicken farm label, and broiler turkeys) cover the majority of chicken meat production in Tunisia. For each sample, DNA was extracted and T. gondii-specific PCR, targeting the B1 gene was performed. The overall molecular prevalence of T. gondii in poultry meat samples was 20% (28/140; 95%CI: 13.3-26.6%). The highest prevalence was observed in chicken farm label (25.7%; 9/35). Prevalence rates were 20.0% (7/35), 20.0% (7/35), and 14.3% (5/35) in broiler chickens, broiler turkeys, and reform laying hens, respectively (p > 0.05). Our finding suggests the involvement of industrial chicken meat, as a potential risk factor of human T. gondii transmission, especially when the latter is consumed undercooked.
