Mystery illness kills thousands

Zapata Palacios passed away on Jan. 26. He was 49.

Working with scientists from Costa Rica, El Salvador and Nicaragua, Wesseling tested groups on the coast and compared them with groups who had similar work habits and exposure to pesticide but lived and worked more than 500 meters (1,500 feet) above sea level.

Under-recognized epidemic?

Some 30 percent of coastal dwellers had elevated levels of creatinine, strongly suggesting environment rather than agrochemicals was to blame, Brooks, the epidemiologist, said. The study is expected to be published in a peer-reviewed journal in coming weeks.

Brooks and Johnson, the kidney specialist, said they have seen echoes of the Central American phenomenon in reports from hot farming areas in Sri Lanka, Egypt and the Indian east coast.

“We don’t really know how widespread this is,” Brooks said. “This may be an under-recognized epidemic.”

Jason Glaser, co-founder of a group working to help victims of the epidemic in Nicaragua, said he and colleagues also have begun receiving reports of mysterious kidney disease among sugar cane workers in Australia.

Despite the growing consensus among international experts, Elsy Brizuela, a doctor who works with an El Salvadoran project to treat workers and research the epidemic, discounts the dehydration theory and insists “the common factor is exposure to herbicides and poisons.”

Nicaragua’s highest rates of chronic kidney disease show up around the Ingenio San Antonio, a plant owned by the Pellas Group conglomerate, whose sugar mill processes nearly half the nation’s sugar. Flores and Zapata Palacios both worked at the plantation.

According to one of Brooks’ studies, about eight years ago the factory started providing electrolyte solution and protein cookies to workers who previously brought their own water to work. But the study also found that some workers were cutting sugar cane for as long as 9 1/2 hours a day with virtually no break and little shade in average temperatures of 30 C (87 F).

In 2006, the plantation, owned by one of the country’s richest families, received $36.5 million in loans from the International Finance Corp., the private-sector arm of the World Bank Group, to buy more land, expand its processing plant and produce more sugar for consumers and ethanol production.

In a statement, the IFC said it had examined the social and environmental impacts of its loans as part of a due diligence process and did not identify kidney disease as something related to the sugar plantation’s operations.

Nonetheless, the statement said, “we are concerned about this disease that affects not only Nicaragua but other countries in the region, and will follow closely any new findings.”

‘Only job in town’

Ariel Granera, a spokesman for the Pellas’ business conglomerate, said that starting as early as 1993 the company had begun taking a wide variety of precautions to avoid heat stress in its workers, from starting their shifts very early in the morning to providing them with many gallons of drinking water per day.

Associated Press reporters saw workers bringing water bottles from their homes, which they refilled during the day from large cylinders of water in the buses that bring them to the fields.

Glaser, the co-founder of the activist group in Nicaragua, La Isla Foundation, said that nonetheless many worker protections in the region are badly enforced by the companies and government regulators, particularly measures to stop workers with failing kidneys from working in the cane fields owned by the Pellas Group and other companies.

Many workers disqualified by tests showing high levels of creatinine go back to work in the fields for subcontractors with less stringent standards, he said. Some use false IDs, or give their IDs to their healthy sons, who then pass the tests and go work in the cane fields, damaging their kidneys.

“This is the only job in town,” Glaser said. “It’s all they’re trained to do. It’s all they know.”

The Ingenio San Antonio mill processes cane from more than 24,000 hectares (60,000 acres) of fields, about half directly owned by the mill and most of the rest by independent farmers.

The trade group for Nicaragua’s sugar companies said the Boston University study had confirmed that “the agricultural sugar industry in Nicaragua has no responsibility whatsoever for chronic renal insufficiency in Nicaragua” because the research found that “in the current body of scientific knowledge there is no way to establish a direct link between sugar cane cultivation and renal insufficiency.”

Brooks, the epidemiologist at Boston University, told the AP that the study simply said there was no definitive scientific proof of the cause, but that all possible connections remained open to future research.

In comparison with Nicaragua, where thousands of kidney disease sufferers work for large sugar estates, in El Salvador many of them are independent small farmers. They blame agricultural chemicals and few appear to have significantly changed their work habits in response to the latest research, which has not received significant publicity in El Salvador.

In Nicaragua, the dangers are better known, but still, workers need jobs. Zapata Palacios left eight children. Three of them work in the cane fields.

Two already show signs of disease.
