| Although usually considered as a food with low contamination levels, powder milk can present bacterial spores such as Bacillus cereus, If the milk is reconstituted and maintained under inadequate temperatures, spores can germinate and the resulting bacterial contamination can cause to food borne infections. To isolate and quantify organisms of the Bacillus cereus species in whole milk powder, 72 samples of the product were collected in stores located in the city of São Paulo in 1987 and 1988.
