LAGRANGE/ELKHART COUNTIES, Ind. (WNDU) - Bird flu has returned to Michiana.

According to Purdue Extension, both LaGrange and Elkhart counties have farms that recently tested positive for the disease.

Those farms are now in quarantine to help prevent bird flu from spreading to other farms.

Producers are urged to maintain strong biosecurity practices. If your farm does not currently have a biosecurity plan, you’re urged to implement one.

You should also avoid sharing equipment or supplies between farms, as they can easily carry the virus.

Common symptoms in poultry include:

Decreased energy, appetite, and egg production

Sudden death without prior signs

Swelling of the head, comb, eyelids, wattles, or hocks

Nasal discharge, coughing, or sneezing

Purple discoloration of wattles, legs
