“When you care about animals, it breaks your heart when the law requires you to do this.”

Former Lab Worker

Lab workers have sounded the alarm on government-mandated toxicity tests on animals. Pressure is mounting to replace animal testing with human-relevant, non-animal methods.

What is Toxicity Testing?

Broken Science icon

Outdated Science

Misleading safety and efficacy results from animal tests are the driving force behind 90% of new medicines failing in human trials. Despite obvious differences in physiology, biochemistry and genetic expression, animals continue to be subjected to toxicity testing. Modern, human-relevant science can better predict human outcomes.

Animal Suffering icon

Animal Suffering

Toxicity testing is the government-mandated exposure of animals to test substances to determine the concentration at which harm, illness or death occurs. Animals are restrained and repeatedly made to inhale, ingest or endure contact with test substances—often at excessively high doses—for drug, pesticide and other product approval.

Human Suffering icon

Human Suffering

Technicians are required to perform distressing tests on animals as part of regulatory approval processes. The untenable moral conflict they face in having to inflict suffering, called the ‘caring/killing’ paradox, can lead to PTSD, secondary trauma, moral injury and depression.

The US Connection

A pivotal moment for the US—and for animals

New footage from two US-owned labs, located in the UK, provides the most extensive insight ever released into the animal impact of toxicity testing. These are not isolated cases, they are standard toxicity testing practices. Each year, millions of animals are used in toxicity tests connected to products sold in the US, including pharmaceutical drugs, industrial chemicals, pesticides, and others. Some of this testing happens inside the US, and some is carried out overseas by or for corporations that do business in the US. These practices persist despite growing scientific recognition that animal models consistently fail to predict human outcomes. They are outdated, unreliable, and cause immense suffering. While the US government has committed to transition away from animal testing and towards modern, human-relevant science, the severe suffering shown in this footage demands far more urgent action. Please us the form below to send a message to US Food and Drug Administration Commissioner, Marty Makary, thanking him for his roadmap to end toxicity testing on animals—and urging him to accelerate the transition to modern, human-relevant science. We have the technology. We have the science. Let’s end toxicity testing on animals now.

Support Animal-free Science

Science and innovation are advancing at a remarkable pace; effective and humane alternatives to animal testing—like organoids and organ-on-a-chip—already exist.

Instead of continuing to subject animals to toxicity tests, modern, non-animal methods can increasingly generate more relevant data on the safety of substances, providing better protections for humans, animals and our environment. Please send an urgent message to {{target_name}} calling on the FDA to urgently replace animal-based toxicity testing requirements with human relevant technologies.
