On May 22, 2012 Maryland Governor Martin O'Malley signed a bill into law to ban the use of arsenic additives in poultry feed. This is the first such ban passed in the United States.
The Maryland State Legisiature requested researchers from the University of Maryland to conduct a literature review on the Environmental Concerns of Arsenic Additives in Poultry Litter. This proved useful to the legisiators in their discussions of banning the use of arsenic in poutlry feed. This report provides a short summary of the findings of the reviews.
