Pick your poison: coronavirus or venomous snakes.

An Australian COVID-19 testing center in St. Mary's had to close after multiple people found venomous red-bellied black snakes on the grounds over the course of several days, according to 9News. The snakes were described as being "medium-sized" and are often found in moist habitats such as streams, swamps, and lagoons, according to the Australian Museum.

Red-bellied black snakes are "one of the most frequently encountered snakes on the east coast of Australia, and are responsible for a number of bites every year," according to the museum. The snakes are said to only bite under "severe molestation."

Employees at the testing center discovered the first snake on Friday, and on Monday, several baby snakes were seen, Sean Cade, the owner of the company Australian Snake Catchers, told the outlet. Cade pointed to "improved weather conditions" and an influx of snake babies being born as a reason for the increased sightings.

Cade posted a video to Facebook showing one of the snakes being directed out from underneath a trash can before being picked up and placed in a collection bag.

Cade confirmed to Newsweek that the snake that had been filmed was released. "All snakes and reptiles are protected by law in Australia," he told the outlet.

While the snakes are frequently sighted outdoors, Cade said this is the "first testing center" that has ever had to close due to venomous snakes, according to the outlet.
