Drinking from a Can? Here’s Why You Might Want to Think Twice

Experts Say the Results Aren’t Surprising
Cedric Spak, an infectious disease specialist at Baylor University Medical Center in Dallas, told CBS that these results don’t surprise him. For example, if an employee doesn’t wash their hands after using the restroom and then handles the cans, contamination is likely.
Additionally, rats and mice are common in warehouses, factories, and supermarkets — and they can leave droppings on top of the cans.

But Don’t Panic Just Yet
Fortunately, not all bacteria survive in cold environments like refrigerators. Plus, our immune systems are constantly dealing with exposure to microorganisms in our daily lives.

Still, if you prefer not to take any chances, there’s an easy fix:
Simply rinse the top of the can under running water before drinking. Better yet, pour the contents into a glass or use a straw.
