Foodborne Diseases (FBDs) are a major cause of morbidity and mortality worldwide, affecting one third of the global human population each year (World Health Organization, 2015a). Foodborne Diseases are caused by a broad range of chemical contaminants, bacteria, virus, parasites and biotoxins, and are often referred as neglected diseases. Despite parasites have not received the same level of attention as other foodborne biological and chemical hazards, they cause a high burden of disease in humans (World Health Organization, 2014). In fact, both Food and Agriculture Organization of the United Nations (FAO) and World Health Organization (WHO) have recently emphasized the global importance of foodborne parasitic diseases (Trevisan et al., 2019). Attending this issue, the FAO/WHO Foodborne Disease Epidemiology Reference Group (FERG) developed a multicriteria-based risk ranking of foodborne parasites at a global level (World Health Organization, 2014). Among the seven most important parasites listed, Taenia solium, Echinococcus granulosus, Toxoplasma gondii, Cryptosporidium spp., and Trichinella spiralis share a common feature: farm animals as important reservoirs (Devleesschauwer et al., 2017). This issue is of great relevance, not only to human health through the spread of FBDs and their consequences, but also to the production of food from animal origin because of the economic losses associated with affected livestock (Gajadhar et al., 2006; Newell et al., 2010). In this regard, the increase in human population and changes in consumer trends (more proteins in diet) will rise
