PETA filed a complaint today with the U.S. Securities and Exchange Commission (SEC) over a series of misleading statements that Charles River Laboratories Inc. has made to shareholders about how it has obtained, imported, and sold countless endangered long-tailed macaques who may have been illegally abducted from their forest homes and falsely labeled as animals bred in captivity.

Charles River, the largest primate experimenter in the U.S., is already under investigation by the SEC over its sourcing of primates and is also under civil and criminal investigation by the U.S. Department of Justice (DOJ) for possible violations of monkey-importation laws.

In a letter sent today to Gurbir S. Grewal, the director of the SEC’s Division of Enforcement, PETA provides evidence that the company has misled shareholders about its ties to the alleged smuggling operation—including that the company has purchased monkeys from the two unindicted coconspirators who were named in a recent trial.

“Charles Rivers Laboratories says one thing and does another, but the evidence is clear: It has been selling monkeys ripped from their forest homes,” says PETA primate scientist Dr. Lisa Jones-Engel. “This risks the spillover of diseases to humans and compromises the results of scientific studies.”

Long-tailed macaques have been driven to the brink of extinction in large part due to the international monkey-laundering business. Importing monkeys also poses a grave and potentially fatal public health risk. Tuberculosis, a highly infectious disease that’s readily transmitted between monkeys and humans, is emerging in primate colonies globally. Monkeys from Cambodia have also been the source of a pathogen so deadly that the U.S. classifies it as a bioterrorism agent.

PETA—whose motto reads, in part, that “animals are not ours to experiment on”—points out thatEvery Animal Is Someone and offers free Empathy Kits for people who need a lesson in kindness. For more information, please visit or follow the group on X, Facebook, or Instagram.
