The claim

Al alimento de pollos en Estados Unidos se agrega medicamentos con arsénico aprobados por la FDA

Original review summary

The review says the claim is false: the FDA told elDetector that since December 31, 2015, no arsenic-based drugs have been approved for use in food-producing animals. It also reports that the FDA’s 2011 study found higher inorganic arsenic levels in the livers of chickens fed roxarsone, but the agency said the detected levels were very low and posed no health risk.[S1]

Additional context

The review says the FDA announced on June 8, 2011, that Alpharma suspended sales of 3-Nitro after an FDA study found higher inorganic arsenic levels in livers of chickens fed the drug than in control chickens. [S1]
