Oysters have been enjoyed for thousands of years, and they remain a delicacy today. National Oyster Day, on August 5, celebrates these shellfish, whether slurped raw on the half shell with lemon, grilled with butter, fried in a po'boy or baked as oysters Rockefeller. Oysters are also environmental heroes, filtering water and creating habitats for other sea life.
History of National Oyster Day
Oysters have been eaten since prehistoric times. Native American peoples along the coasts harvested oysters, leaving behind huge piles of shells called middens, some thousands of years old.
In the 1800s, oysters were so plentiful in places like New York Harbor and the Chesapeake Bay that they were cheap street food. New York was famous for its oyster cellars, and oysters were shipped inland by rail. However, overharvesting, pollution and disease caused oyster populations to collapse in many areas.
Today, oyster farming, or aquaculture, provides much of the oyster supply, and restoration projects work to rebuild wild reefs. Projects such as New York's Billion Oyster Project aim to restore oysters to local waters. Who created National Oyster Day is not documented.
Why National Oyster Day Matters
Oysters are filter feeders: a single adult oyster can filter many gallons of water each day, helping keep coastal waters clean.
Oyster reefs provide habitat for fish and crabs and help protect shorelines from erosion.
Oyster farming supports coastal communities and is considered one of the more sustainable forms of seafood, since farmed oysters don't need to be fed and can improve water quality.
How to Celebrate National Oyster Day
- Try raw oysters: sample different varieties with lemon or mignonette.
- Grill oysters: cook them with garlic butter.
- Make a po'boy: try a fried oyster sandwich.
- Visit an oyster bar: support local shellfish farmers.
- Support restoration: donate shells to reef recycling programs.
Celebrating at Work, School and Home
At work, an oyster tasting can be a special treat, but always offer alternatives for people with shellfish allergies. In classrooms, students can learn about filter feeders by observing how oysters clean water, study oyster reef ecosystems or learn about the history of New York's oyster industry. At home, families can try grilled or fried oysters, visit an oyster farm, or volunteer for a shell recycling program. Raw oysters can carry bacteria; people with certain health conditions, pregnant people and young children should eat them only cooked.
