📅 From Ancient Plate to Modern Table: A Timeline
Triassic & Stone Age: Fossil evidence shows oysters have existed since the Triassic period—over 200 million years ago. Humans have eaten oysters for at least 164,000 years.
Greek & Roman Era: The Greeks pioneered oyster cultivation over 2,000 years ago, dropping pottery shards into the sea to collect spat (baby oysters). Romans expanded on this, farming oysters for elite tables .
18th–19th Century “Golden Age”: Oysters were super cheap and everywhere, especially in New York Harbor—which once held half the world’s oyster beds. Railroad, refrigeration, and canning made oysters widespread.
20th Century Decline: Overharvesting, pollution, and disease devastated oyster reefs—turning yesterday’s staple into a today’s luxury.
Today, National Oyster Day shines a spotlight on these remarkable mollusks—celebrating their flavor, history, and their crucial role in marine ecosystems.
🎉 How to Celebrate National Oyster Day
Slurp some oysters
Raw on the half-shell with lemon, mignonette, cocktail sauce—or take it upscale with angels on horseback (oysters wrapped in bacon).
If raw isn’t your thing, try fried, grilled, smoked, or even on pizza.
Host an oyster party
Set up a tasting bar with East Coast and West Coast varieties. Serve different toppings (hot sauce, shallot mignonette, horseradish) and pair with crisp white wine or champagne. Provide an oyster shucking station—grab gloves and shucking mats for safety.Visit a raw bar or oyster festival
Many seafood restaurants run oyster specials and tastings on August 5.
Check for regional oyster fests, such as Milford Oyster Festival (Connecticut) or Norwalk Oyster Festival (Connecticut).
If you are going to be in Ireland in late September, check out the Galway International Oyster Festival.
Support oyster reefs
Oysters filter up to 50 gallons of water per day—per oyster!
To grow, oysters do not require additional nutrients or food sources other than what is already in their water habitat. They don’t pollute the water they grow in, they clean it! Consider helping our ocean's unsung heroes by donating to the World Wildlife Fund!
🦪 Fun Facts to Impress at the Raw Bar
Pearl chance? Slim to none. Edible oysters (family Ostreidae) don’t usually produce pearls—those come from pearl oysters (Pteriidae), found in deeper waters.
Flavor from “merroir.” East Coast oysters are often briny and firm, while West Coast varieties lean toward buttery or sweet.
Tiny water filters: One adult oyster can filter 50 gallons a day; a healthy oyster reef can filter millions of gallons a day!.
They’re nutrient-rich: Low‑calorie protein powerhouses, oysters are packed with zinc, iron, calcium, selenium, and vitamins A, B12, C, D.
Gender-bending bivalves: Many species start life male and shift to female as they age.
Oyster ice cream exists: A savory ice cream flavor from an 1824 cookbook. Find the original recipe here.
