At least 43 primates were at large Thursday in a South Carolina town where authorities “strongly advised” residents to keep their doors and windows locked after the animals escaped from a research lab.

“No individuals have been accounted for at this time,” Yemassee police said in a statement posted on their Facebook page.

According to the Beaufort County Sheriff’s Office, traps were set around the Alpha Genesis Primate Research Center in Yemassee, where the rhesus macaques escaped en masse around 1 p.m. ET on Wednesday.

According to the sheriff’s office, Yemassee police officers used thermal imaging cameras to search for the furry escapees, which can grow up to 21 inches tall and weigh 15 pounds.

“Residents are strongly encouraged to secure doors and windows to prevent these animals from entering their homes,” the sheriff’s office said. “If you spot any of the escaped animals, please call 911 immediately and do not approach them again.”

Police said they were working with staff at the Alpha Genesis Primate Research Center to find the escapees.

“We would like to reassure the community that these animals pose no health risk,” police said.

Representatives from the Alpha Genesis Primate Research Center could not immediately be contacted for comment.

According to its website, Alpha Genesis “offers the highest quality non-human primate products and bioresearch services worldwide,” including serum, plasma, whole blood and tissue samples.
