name three contaminants in food and their health effects
Answers
Answer:
the contaminants are
Traditionally, we taught that there were three types of food contamination: physical, chemical, and microbial (sometimes called biological). These days, we add a fourth type: allergenic. All food is at risk from these four types of contamination
health effects
Foodborne diseases number about 48 million illnesses annually in the US. (Gould et al., 2013) Chemically contaminated food has serious implications on the health of individuals. The harmful effects range from minor gastric problems to major health fatalities. Chemical contaminants are strongly linked with severe consequences, lack of personal control, and long-term effects (Kheer et al., 2011). Food consumption is the most likely source of human exposure to metals. Metals such as cadmium and lead can easily enter the food chain. Heavy metals can seriously deplete specific nutrients in the body that can decline the immunological defenses, impair psycho-social facilities, and cause intrauterine growth retardation. Heavy metal consumption is also associated with malnutrition and increases the rates of gastrointestinal diseases (Khan et al., 2008). Food contaminants are also a leading cause of cancer (Abet, 2007) Polychlorinated biphenyls (PCBs) exposure due to food contamination can adversely affect children's neurological development and the immune response (Schantz et al., 2004). Pesticides in the food as contaminants also show severe health implications. Excessive levels of these chemicals in the food cause neural and kidney damage, congenital disabilities, reproductive problems, and can prove to be carcinogenic (Basil et al., 2007). The accumulation of pesticides in the tissues of the body can also result in metabolic degradation (Androutsopoulos et al., 2013). There is also the risk of neurodevelopmental disorders like attention deficit disorders, autism, cerebral palsy and mental retardation caused by industrial chemicals like arsenic, PCBs, and lead in both food and water. Exposure to such chemicals in the fetal stages of development can cause brain injury and such lifelong disabilities at much lower doses than those which can affect adult brain function (Grand jean and Landorian, 2006).
