Waiving the Dermal LD50 is an excellent way to kick off this initiative and will save around 3,000 animals each year. We applaud registrants who have proactively facilitated this project and encourage all registrants to support these efforts and submit internal data which would fortify and hasten EPA’s analyses.
EPA Says New Technologies Will Better Protect Human Health and Reduce Costs
The Environmental Protection Agency announced today in a letter to
stakeholders from the Director of the Office of Pesticide Programs that to
“better ensure protection of human health … its immediate goal is to
significantly reduce the use of animals” in pesticides testing requirements
collectively called the “6-pack.”
The 6-pack includes three acute lethal dose oral, inhalation, and dermal
toxicity tests. These tests are considered poisoning tests which assess the
dose at which 50 percent of the animals in the test are killed by the test
chemical. Also included are the Draize eye and skin irritation tests, and
skin sensitization.
Understanding the potential effects of chemicals on humans for these serious
effects is important to protecting workers and the public, and it is
essential that regulatory requirements keep pace with scientific progress.
Alternative methods can save time and resources and often use human tissues,
offering more accurate predictions of human toxicity.
The EPA letter accompanies the finalization of guidance outlining a process
to evaluate and implement alternative test methods, the release of a draft
policy to waive the acute dermal toxicity tests for formulated pesticide
products, and the initiation of several data analyses which will support the
reduction or replacement of other 6-pack tests.
“We support EPA’s efforts to replace these animal tests with methods which
are more relevant to human toxicity and more humane,” says Kristie Sullivan,
M.P.H., director of regulatory testing issues for the Physicians Committee.
“Waiving the Dermal LD50 is an excellent way to kick off this initiative
and will save around 3,000 animals each year. We applaud registrants who
have proactively facilitated this project and encourage all registrants to
support these efforts and submit internal data which would fortify and
hasten EPA’s analyses.”
The Physicians Committee has been a driving force in the stakeholder process
described by the letter, which includes EPA, nonprofit, industry, and
test-method developers working cooperatively to accomplish the goal of
remaking the 6-pack.
