Red Algal Bloom

Pearly Whirly Pearl Fact: Never Eat Oysters During These Months

Have you ever heard that you should only eat oysters in months with names that include the letter “R”? Turns out, there’s truth to the tale!

So why should you avoid eating local oysters in the months of May, June, July, and August?

Oysters are filter feeders that eat algae and plankton and are susceptible to a very specific type of algal bloom, or “Red Tide” that can occur during warmer months of the year. A buildup of toxins in the oyster’s tissue as a result of this algae can be harmful to humans.

So what’s an oyster lover to do?

The answer is actually quite simple. While this old rule is a word to the wise for those of us who like to gather our own oysters to eat from rivers and oceans, it doesn’t usually apply to commercially available oysters, which are strictly regulated by the U.S. government. You can rest assured that your favorite oyster joint is probably serving oysters that are algae free and delicious. Slurp!
