Lorsban is the market name for Chlorpyrifos. It is an organophosphate insecticide patented in 1966 by Dow Chemical Company. It is usually applied to crops and buildings to kill several pests, including insects and worms. This chemical works by quickly killing invasive insects. It also attacks their nervous system and penetrates the surrounding soil. In doing so, it provides long-term protection from common pests. According to the Environmental Protection Agency (EPA), Chlorpyrifos is the most regular used insecticide in the U.S. There are roughly 6 million pounds used on around 10 million acres between 2009 and 2013.


The EPA researchers found that exposure to Chlorpyrifos leads to birth defects. This is the main ingredient used in the insecticide Lorsban. These birth defects resulted in delayed neurologic development, breathing difficulties, and learning disorders.

The EPA acknowledged for decades that Chlorpyrifos could cause acute poisoning. Thus, in the early 2000s, they prohibited its use in most home products. Yet, despite the agency’s recognition of mounting evidence that prenatal exposure could have lasting effects on children’s brains. They went against their proposal and reversed their own ban on insecticide. They knew the risks of exposure to your child; yet, they chose not to take action.


All across the nation, hard-working parents are burdened with the reality of the costly and critical birth defect diagnosis in their children. According to the Centers for Disease Control and Prevention (CDC), birth defects affect one in every 33 babies. That is about 3% of all babies born in the United States each year. Sadly, birth defects are the leading cause of infant deaths, accounting for 20% of all infant deaths.

It is unfortunate that many parents find themselves buried by the costs of caring for a child whose birth defect is the direct result of another party’s negligence. Dow Chemical Co. knowingly exposed many people – including pregnant women – to the toxic chemical Lorsban. As a matter of fact, there is extensive research showing this may greatly increase the risk of the development of a birth defect in their child. This is an egregious injustice.
