The monkeys made a break for it Wednesday after an employee at the Alpha Genesis facility in Yemassee didn’t fully lock a door as she checked on them, officials say.
One of 43 monkeys bred for medical research that escaped a compound in South Carolina has been recovered unharmed, officials said Saturday. Many of the others are still located a few yards from the property, jumping back and forth over the facility’s fence, police said in a statement. The Rhesus macaques made a break for it Wednesday after an employee at the Alpha Genesis facility in Yemassee didn’t fully lock a door as she fed and checked on them, officials said. “They are very social monkeys and they travel in groups, so when the first couple go out the door the others tend to just follow right along,” Alpha Genesis CEO Greg Westergaard told CBS News. Westergaard said his main goal is to have the monkeys returned safely with no other problems. “I think they are having an adventure,” he said. The monkeys on Friday were exploring the outer fence of the Alpha Genesis compound and are cooing at the monkeys inside, police said in a statement.
“The primates are exhibiting calm and playful behavior, which is a positive indication,” the police statement said, adding company workers are closely watching the monkeys while keeping their distance as they work to safely recapture them. The monkeys are about the size of a cat. They are all females weighing about 7 pounds (3 kilograms). Alpha Genesis, federal health officials and police all said the monkeys pose no risk to public health. The facility breeds the monkeys to sell to medical and other researchers.
“They are not infected with any disease whatsoever. They are harmless and a little skittish,” Yemassee Police Chief Gregory Alexander said Thursday. Authorities still recommend that people who live near the compound about 1 mile (1.6 kilometers) from downtown Yemassee shut their windows and doors and call 911 if they see the monkeys. Approaching them could make them more skittish and harder to capture, officials said. Eve Cooper, a biology professor at the University of Colorado Boulder who has studied rhesus macaques, said the animals have the potential to be dangerous and urged people to keep their distance. Rhesus macaques monkeys can be aggressive. And some carry the herpes B virus, which can be fatal to humans, Cooper said. However, Alpha Genesis states on its website that it specializes in pathogen-free primates. Cooper noted that there are pathogen-free populations of rhesus macaques that have been quarantined and tested.
