Before the 19th century, sugarcane was a luxury product for the rich, harvested by poor slaves working in the tropical fields in Central America. Even though you do not hear so much now about sugarcane and slavery in its traditional sense, the differences between the people on the consuming and the producing end are stark. In terms of consumption, sugar is often mentioned in relation to diseases such as addiction and obesity. With regard to production, sugarcane is increasingly linked to an epidemic that is affecting poor workers: Chronic Kidney Disease of non-Traditional causes (CKDnT).
Three of the most likely causes of CKDnT are dehydration, heat stress and exposure to agrochemicals. The sugarcane industry in Central America is beset by poor working conditions, such as long working days and heavy physical work with little access to water and shade, which most likely contribute to the onset of the disease.
The disease has so far been established in most sugarcane producing countries in Central America and new cases are constantly emerging. It is characterized by an increasing failure of kidney functions, ultimately resulting in the death of the patient if left untreated. The progression of the disease can be slowed down with medicine and dialysis. Currently, only a transplant can save a patient suffering from CKDnT. However, few sugarcane workers can afford dialysis or medicine, let alone a transplant.
