Law enforcement officials in South Carolina captured one of the 43 primates that recently escaped from a biomedical research lab and asked the public to be on the lookout for other monkeys.

On Saturday evening, the Yemassee Police Department announced that a young female rhesus macaque monkey had been safely captured and brought back to the Alpha Genesis Primate Research Center lab where she belongs.

“She is well and having a peanut butter and jelly sandwich,” Alpha Genesis CEO Greg Westergaard said in a statement obtained by ABC News. 

That’s just one down, 42 more to go.

The monkey is part of the group of young female monkeys that escalated from the lab on Thursday after a caretaker failed to secure a door. Alpha Genesis is a company that provides pathogen-free primates for biomedical research worldwide.

The company said the monkeys that have escaped do not pose a threat to the public because they have never been tested on and are too young to carry disease. However, Alpha Genesis asked that the public be aware of other potential escaped monkeys that have escaped and not interact with them.

They have specifically asked people not to fly drones in the vicinity where they escaped to prevent the primates from being spooked.

Currently, a group of primates are residing along the facility’s fence line and have continued to engage with other primates inside the facility.

Alpha Genesis said they are “actively deploying” traps baited with food in the hopes of capturing the other monkeys.

Rhesus macaque primates have been used for nonhuman testing for centuries because they share 93 percent of DNA with humans. They have been crucial in developing lifesaving vaccines like those for Covid-19.

For those who support using nonhuman primates for medical research, maintaining a supply of monkeys is essential for biomedical development.

Alpha Genesis provides the primates by using their facilities as a breeding ground to raise the animals for research purposes.

This is not the first time the primates have escaped from the facility. In 2016, more than two dozen primates escaped but were later captured, according to the Post and Courier.
