Abstract

Hydatid cyst contamination in food presents a persistent and pervasive threat to public health. Hence, several studies have been published on hydatid cysts in raw meat products. The current study aimed to meta-analyze the prevalence of hydatid cysts in meat. The search was performed in international databases, including PubMed, Web of Science, Scopus, and Google Scholar, from January 1, 2000, to February 10, 2024. A meta-analysis of prevalence was conducted using the metaprop command in the subgroups of countries, animals, and WHO regions. Meta-regression of the prevalence of hydatid cysts in meat over time and sanitation services ranking was conducted using a random effects model (restricted maximum--likelihood). Fifty-seven published references with 130 data reports were included in the study. The lowest and highest prevalence of hydatid cysts in raw meat was observed in Sudan at 0.01%, 95%CI (0.01-0.02) and Italy at 69.86%, 95%CI (68.14-71.55), respectively. The highest prevalence of hydatid cysts was observed in Sheep (12.32%), Cattle (11.85%), and Buffalo (10.65%). The lowest and highest prevalence of hydatid cysts was South-East Asian Reg (2.77%) and European Region (33.21%), respectively. Meta-regression showed that the prevalence of hydatid cysts has significantly decreased over time (p-value = 0.021) and insignificantly decreased with sanitation services ranking (p-value = 0.679). Therefore, in order to maintain the existing conditions and even reduce the burden of hydatidosis, public health education, promotion of hygienic practices, and investment need to be carried out continuously.
