BURLINGTON (WITI) --The eight-alarm fire that broke out at Echo Lake Foods in Burlington Wednesday evening, January 30th has been contained. Fire officials are currently working on hot spots.

The massive fire broke out around 6 p.m. in the production area of the factory and prompted assistance from 88 agencies throughout southeast Wisconsin and northern Illinois. Wisconsin Emergency Management was also called to the scene to assist with resources.

The State Regional Hazardous Materials Response Team from Racine was also called to the scene to monitor air quality because the plant utilizes ammonia. Officials say there has been some minor release of ammonia residue from pipes -- which has been contained.

Authorities say firefighters were having difficulty fighting this fire, saying this was likely due to burning oil. Additionally, the bitter temperatures caused some problems with equipment freezing up.
