Authorities say five people have been taken to a hospital after an ammonia leak at a west Phoenix dairy.

Officials of the Shamrock Farms Dairy say there was a leak in an ammonia holding tank at the company's processing plant Friday afternoon, but it now has been contained.

Phoenix Fire Department officials say multiple people at the scene complained about burning eyes and five people were transported for further evaluation at medical facilities.

All were men between the ages of 35-65.

It isn't immediately clear if the five are employees of the dairy.
