Although any mammal can have a seroma, deer are commonly affected.

Is This Animal Infected?

Yellow or reddish, clear fluid under skin or within muscle.

Can be large (football-sized) and contain more than a gallon of fluid.

Often present between front legs.

Can make it difficult for the animal to move.

Affected animals may be easier prey.

Protect Myself and Others

  • Affected tissue is unappetizing and should not be eaten.
  • Once affected tissue has been trimmed away, the meat can be cooked and eaten.
  • Any meat surrounding a seroma is safe to eat.

Safe for Pets?

Yes. The meat is safe for pets to eat after it has been cooked properly.

What Causes It?

  • Localized soft-tissue injury: not caused by an infection; does not contain “pus.”
  • Fluid (blood serum) seeps from tiny ruptured blood vessels in injured areas.
  • Fluid accumulates, often under the skin, and usually drains away after some time.
