Erysipeloid is an acute bacterial infection of the skin and other organs caused by the microorganism Erysipelothrix rusiopathiae.

Human infection is acquired through direct contact with the meat of infected animals, poultry, fish and shellfish. Infection can occur only if the person has an abrasion or cut that allows entry of the bacteria. People at risk include fisherman, farmers, butchers, abattoir workers, veterinary surgeons and cooks.
