Oyster Day is a celebration of this most versatile mollusc. Oyster is the common name for a number of different groups of bivalve molluscs. Some species of oysters are commonly eaten, either cooked or raw, as a delicacy. While other types of oyster, such as pearl oysters, are not normally consumed by humans, they are harvested for their pearls.
The history of Oyster Day is unknown, but the history of human’s relationship with oysters is very long, since Roman times there is evidence of people in the United Kingdom and France farming oysters. In the 19th century New York harbour was the largest producer of oysters in the world and provided nutritious food for thousands of people. Nowadays Oyster Day is most widely celebrated in America and the UK, with many festivals to celebrate this culinary delicacy. People celebrate by eating fresh oysters or buying oyster pearls for loved ones.
