''Bacillus licheniformis'' is a bacterium that is commonly found in soil and bird feathers. Birds that tend to stay on the ground more than the air (i.e. sparrows) and on the water (i.e. ducks) are common carriers of this bacterium; it is mostly found around the bird's chest area and back plumage.
 
''Bacillus licheniformis'' is part of the subtilis group along with ''Bacillus subtilis'' and ''Bacillus pumilus''. These bacteria are commonly known to cause food poisoning and food spoilage. ''Bacillus licheniformis'' also is known for contaminating dairy products. Food borne outbreaks usually involve cases of cooked meats and vegetables, raw milk, and industrially produced baby food contaminated with ''Bacillus licheniformis''.
