SAO PAULO, Nov 1 (Reuters) - Soy farming has been linked to a rise in child cancer deaths in Brazil, the world's biggest producer and exporter of the oilseed and one of the top users of pesticides for protecting crops from disease and pests, according to a study in the South American country.The peer-reviewed study published on Monday in PNAS, the journal of the U.S. National Academy of Sciences, found that as soy cultivation expanded in Brazil, "agricultural pesticide exposure was associated with increased childhood cancer mortality among the broader population indirectly exposed to these chemicals."
The U.S. researchers found a relationship between soy production and related community exposure to agrochemicals including glyphosate, a widely used weedkiller that some genetically modified soybean seeds are designed to tolerate.
"We find a statistically significant increase in pediatric leukemia following expanded local soy production," the PNAS article said, based on Brazilian childhood cancer incidence and disease mortality data spanning 15 years.
With the use of GMO soy on increasingly larger areas, Brazil's production nearly doubled over the last decade, to a record 154.6 million metric tons this year, according to Brazilian government data.
The country sells most of its soybean exports to China and for years has been competing with the United States, where chemicals such as glyphosate are also widely used, in global soy markets.
