Did you know?
Oysters are ecosystem engineers — a single oyster filters up to 50 gallons of water per day removing sediment, nitrogen, and algae. One acre of oyster reef can filter the water equivalent of an Olympic swimming pool in just 17 hours. Oysters were so abundant in New York Harbor that they once formed reefs visible above the water surface.

What You Need to Know
Oysters are exceptionally rich in zinc — the highest dietary zinc source available. In very small amounts this is beneficial for immune function and coat health. However too much zinc causes toxicity. Oysters also contain copper which can be problematic in large amounts. Plain cooked fresh oysters in very small amounts are acceptable. Raw oysters are never appropriate.
