Abstract: At 10:45 a.m. on March 10, 1996, Employee #1, a newly hired cage cleaner at Coyote Point Natural History Museum in San Mateo, CA, entered a passage that connected the river otter cages with the otter exhibit compound. She was being trained as an animal keeper, and her trainer was outside the cyclone fence passage. Employee #1 was herding the otters from their cages into the exhibit area when a 3- year-old male attacked her and bit her repeatedly on the legs. After numerous attempts, the trainer forced the otters back into their cage and called 911. Employee #1's injuries resulted in disfiguring scars. This had been her first time alone with the otters, and she had not been provided with any personal protective equipment.
