The EPA scraps plan that would have had it ban mammal testing in favor of computer models
The Environmental Protection Agency has scrapped a plan to phase out mammal testing for studying chemical toxicity.
The call to challenge the status quo was controversial from the start — it not only was going to impact thousands of studies and experiments, but many scientists argued that computer models were nowhere near ready to replace animals as test subjects. In a letter written by a group of public health officials, the experts urged the EPA’s head Michael Regan to reconsider the ban because computational models, in their opinion, were “not yet developed to the point” where they could be relied on for risk assessments. While the EPA hasn’t made any official statements about how it plans to work toward its original goal, now without a deadline, some studies have shown promise that computational models might effectively reflect the toxicology of certain chemicals during testing.
