Effect of maternal aflatoxin exposure on growth and morbidity of infants 0 to 3 months

Abstract

Aflatoxin exposure has been implicated in adverse human health outcomes in areas where the toxin is prevalent in foods [1]. Consequently, many people may be chronically exposed to large amounts of the toxin worldwide. The effect of aflatoxin exposure is felt more in developing countries and this may be attributed to high levels of malnutrition coupled with chronic exposure to high levels of the toxin in their diets [2]. Consumption of high levels of aflatoxins has been associated with aflatoxicosis resulting in death, while chronic dietary exposure to aflatoxins is associated with liver and other cancers and poor growth outcomes in young children [3]. Exposure of infants to aflatoxins may be detrimental to their normal growth and other aspects of health later in life. Early linear growth retardation is associated with poor cognitive development, reduced physical productivity, a greater risk of poor pregnancy outcomes later in life, including low birth weight babies and a greater risk of obesity, coronary heart disease, diabetes and hypertension later in life [3]. Therefore, protection of fetuses, infants and young children from the effects of aflatoxins through maternal exposure would not only reduce the risk of them not realizing their cognitive potential, but also contribute to reducing the risk of non-communicable diseases whose prevalence is on the rise, not just in developed countries, but also in developing countries.
