International Primate Day 2019 – Letter to Representatives

Posted: 30 August 2019. Updated: 30 August 2019


For International Primate Day on September 1, Animal Defenders International (ADI) is calling on Congress to take a stand against the high, and growing, number of primates used in research by supporting advanced, human-relevant research methods and a phase-out of primate use. Find out more here.

Using the template letter below, please urge your legislators to to do so too. Find their details and contact them here.

Support our campaign to save the primates.


Most people consider the use of primates in research to be unacceptable.

Despite this, the numbers used in US labs is rising. Nearly 76,000 primates were used in 2017 alone, an increase of more than 6% over the previous year.

Many primates are used for regulatory safety testing, being force-fed or injected with toxic or potentially toxic substances while restrained, such tests shown to produce misleading results due to species differences.

A shocking number of the primates used in research are imported into the US – more than 21,000 according to latest figures.

ADI has conducted investigations of primate suppliers around the world. At Biodia, a key breeding facility in Mauritius (one of the world’s largest suppliers), ADI filmed baby monkeys being torn from their screaming mothers to be tattooed, pregnant monkeys manhandled and pinned down, and monkeys swung by their tails. At supplier Nafovanny in Vietnam, ADI filmed monkeys living in deplorable conditions, with some animals confined to small rusting cages that were in a state of collapse.

Replacing primates with advanced, human-relevant research methods provides results which are more relevant to people.

For the sake of the animals and science, and as your constituent, I hope I can count on your support for a phase-out of the use of primates in research.

I look forward to hearing from you soon.
