WASHINGTON, July 14, 2026 /PRNewswire/ — **On** **July 14, 2026, the U.S. Fish and
Wildlife Service ("USFWS") for the second time declined to accept a petition filed
by People for the Ethical Treatment of Animals ("PETA") and other activist groups
to list long-tailed macaque ("LTM") monkeys (****_Macaca fascicularis_****) under
the U.S. Endangered Species Act ("ESA").**

The U.S. Fish and Wildlife Service determined that PETA’s petition^(1) to list LTM
monkeys under the ESA does not present substantial scientific information warranting
further review. This is the second time USFWS has rejected a petition from PETA 
to list this nonhuman primate species in the last three years^(2).

"The National Association for Biomedical Research commends USFWS for conducting 
a thorough, science-based review of the petition submitted by activist groups and
for its determination that LTM monkeys do not warrant listing under the ESA," said
Matthew R. Bailey, president, National Association for Biomedical Research (NABR).

"It is clear from the record that activist groups like PETA have attempted to weaponize
the ESA and other environmental processes to block or hinder medical research in
the United States and around the world. Doing so not only jeopardizes human health
and safety, but it undermines the value of these environmental processes when they
are used as tools to further political agendas," added Mr. Bailey.

"NABR will continue to engage in these processes to protect medical research in 
the U.S. and around the world to ensure decisions regarding species protection are
based on the best available scientific and commercial data."

LTM monkeys are used extensively throughout the world in biomedical research given
their close approximation to human beings. The importation and use of this nonhuman
primate species in biomedical research is strictly regulated by international bodies
and U.S. federal agencies.

Medical research using LTM monkeys has been crucial for advances in regenerative
medicine^(3), immunology^(4), cancer^(5), vaccine development^(6), and pharmacology
^(7). The National Institutes of Health (NIH) recently published a review confirming
the importance of LTM monkeys in conducting biomedical research^(8).

"Due to their physiological and biological similarities with humans, LTM monkeys
are a crucial resource for pre-clinical biomedical research. They contribute to 
the development of therapies before the human clinical trial stage of development,"
said Mr. Bailey. "LTM monkeys have been instrumental in the development, and in 
safety and efficacy assessment, of many of today’s medicines and treatments. They
continue to be invaluable for biomedical advancements."

**About the National Association for Biomedical ResearchFounded in 1979, the National
Association for Biomedical Research (NABR) is the only 501(c)(6) nonprofit association
dedicated to sound public policy for the humane use of animals in biomedical research,
education, and testing. Members include more than 280 universities, medical and 
veterinary schools, teaching hospitals, pharmaceutical and biotechnology companies,
