Abstract
Public health and the economy are seriously affected by diseases transmitted by meat and its products, including Zoonotic diseases. Several factors contribute to carcass condemnation in slaughterhouses, such as parasitic infections that can be extremely harmful to human societies. Parasites transmitted from red meat and its products can induce disorders in humans. These parasites include helminths such as Taenia spp. (intestinal disorders), liver flukes (hepatic disorders), and Trichinella spp. (intestinal and muscular disorders), as well as protozoans such as Toxoplasma gondii (neurological and reproductive disorders) and Sarcocystis spp. (gastrointestinal, respiratory, and muscle disorders) and Cryptosporidium spp. (intestinal disorders and severe diarrhea). Generally, there is little knowledge about meat-borne parasitic diseases. Global food trade, population growth, unprincipled cooking methods, and lack of improvement in monitoring and diagnostic procedures are among the increasing factors of diagnostic cases of parasitic diseases caused by meat and meat products around the world, including Iran. Despite the decrease in meat consumption per capita in recent years, there is a significant prevalence of meat-borne parasitic diseases among Iranian population, which requires attention towards preventive and monitoring methods. Iran's northern provinces, including Gilan and Mazandaran, have the highest documented incidence of parasite infections in meat, especially in rural areas with humid climates where cattle are raised. Recent studies have estimated the prevalence of human infections in Iran. The studied diseases included taeniasis (0.25%-0 5%), trichinellosis (2.6% in high-risk group), fascioliasis (0.7% in Jolfa county), dicrocoeliasis (2.2% in Meshkinshahr city), toxoplasmosis (39.3% of the whole Iranian population), sarcocystosis (0.16%-0.1%, only found in eight cases), cryptosporidiosis (2.9% of healthy population and 1.3% of patients suffering from gastroenteritis). Therefore, this study aimed to evaluate the essential parasitic diseases transmitted through meat and meat products in the geographical area of Iran and their effects on both human and animal health.
