Abstract
Foodborne diseases (FBDs) are a major concern worldwide since they are associated with high mortality and morbidity in the human population. Among the causative agents of FBDs, Taenia solium, Echinococcus granulosus, Toxoplasma gondii, Cryptosporidium spp., and Trichinella spiralis are listed in the top global risk ranking of foodborne parasites. One common feature between them is that they affect domestic livestock, encompassing an enormous risk to global food production and human health from farm to fork, infecting animals, and people either directly or indirectly. Several approaches have been employed to control FBDs caused by parasites, including veterinary vaccines for livestock. Veterinary vaccines against foodborne parasites not only improve the animal health by controlling animal infections but also contribute to increase public health by controlling an important source of FBDs. In the present review, we discuss the advances in the development of veterinary vaccines for domestic livestock as a strategy to control foodborne parasitic diseases.
Highlights
Foodborne Diseases (FBDs) are a major cause of morbidity and mortality worldwide, affecting onethird of the global human population each year (World Health Organization, 2015a)
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 this review we will summarize the advances, future perspectives, and challenges in the development of veterinary vaccines for domestic livestock as a control strategy against FBDs caused by T. solium, E. granulosus, T. gondii, Cryptosporidium spp., and T. spiralis
Summary
Foodborne Diseases (FBDs) are a major cause of morbidity and mortality worldwide, affecting onethird of the global human population each year (World Health Organization, 2015a). 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, to human health through the spread of FBDs and their consequences, and 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). Livestock generate large volumes of feces, which can contaminate the environment with (oo)cysts or eggs, contributing to increase the prevalence of infections transmitted by some of these parasites in domestic animals (Fayer et al, 2010) In this sense, it is necessary to establish efficient strategies to control FBDs caused by these parasites in order to reduce the effects on animal and human health (Robertson et al, 2014). In this review we will summarize the advances, future perspectives, and challenges in the development of veterinary vaccines for domestic livestock as a control strategy against FBDs caused by T. solium, E. granulosus, T. gondii, Cryptosporidium spp., and T. spiralis
