Patrick Cudahy

Patrick Cudahy meat packing plant in Wisconsin, authorities said. An official of the Cudahy fire department, who declined to be named, said he did not have details on whether anyone was injured in the fire that broke out on Sunday night. Media reports said people living within a 1-mile (1.6 km) area of the plant south of Milwaukee were asked to evacuate their homes because of low levels of ammonia seeping into the air.

Patrick Cudahy specializes in branded packaged meats, including bacon, ham and sliced meats. One of its most popular brands is the Sweet Apple-Wood Smoke Flavor bacon. About 100 firefighters worked through the night and were still fighting the blaze Monday morning at the Patrick Cudahy Inc. plant in Cudahy. No injuries were reported.

Residents living within a mile of the plant were told to evacuate the area because of possible ammonia fumes, Mayor Ryan McCue said. A local school was made available for evacuees and their pets to take shelter. Rebecca Spencer, who lives about a quarter mile from the plant, left her home with her dog and two cats. She said she wasn’t worried when she saw huge plumes of black smoke because she was confident firefighters would contain the blaze.
