Bacillus cereus in infant foods and dried milk products

Identification of contamination sources of Bacillus cereus in pasteurized milk

“…Thirty-five percent of pasteurized milk, 63% of milk powder, 50% of infant food (based on milk) and 14% of icecream sarnples have been found to be contaminated with B. cereus, with the counts being from 0.3 to 800 CFUIg or ml (Ahmed et al, 1983;Wong, et al,, 1988a;Becker, et al, 1994).…”

Effect of omitting teat preparation on bacterial levels in bulk tank milk

“…The practice of dry wiping teats to remove debris prior to cluster attachment was also associated with lowering the presumptive Bacillus cereus count in bulk tank milk when animals were managed outdoors . B. cereus s. l. are specific thermoduric bacteria that are resistant to pasteurisation (Granum, 2005) and have been isolated from pasteurised dairy products (Becker et al, 1994;Lin et al, 1998;Larsen and Jorgensen, 1999) and, therefore, are of particular interest to the Irish dairy industry. B. cereus s. l. is abundant in soil; therefore, removing dry soil and dirt from contaminated of teats) (>30% of surface area caked with dirt), based on the scorecard developed by Schreiner and Ruegg (2003), were washed and dried before cluster application.…”

Bacillus amyloliquefaciens bacteriemia in two preterm neonates: A significant catheter-related invasive infection in neonates

“…Bacillus amyloliquefaciens, a gram-positive, rod-shaped, oval spore forming, aerobe bacterium of the family Bacillaceae, that is found commonly in soil, air [6], food, such as dried milk products [7], and many other sources, is the main strain implicated in production of α-amylase and protease [8,9]. Few studies also described this organism found on the hands of nursing staff or alcoholic preparation [10].…”

“…A food contamination has not totally been excluded due to the use of B. amyloliquefaciens in food industry but symptoms may appear 10 to 14 h following ingestion of foodstuffs contaminated with enterotoxigenic strains. Foods most often implicated in the diarrheal syndrome include poultry, cooked meats, soups, desserts, and occasionally fluid and dry milk products [7].…”

“…Advances in neonatal intensive care over the past several years have improved survival of very low birth weight neonates, but due to their immature immune systems as well as their being subjected to prolonged mechanical ventilation and frequent use of long term intravascular catheter, members of this vulnerable population are particularly susceptible to disseminated disease caused by environmental organisms such as Bacillus [6,7,14,15,[18][19][20][21].…”
