Abstract
Bacilius cereus is a great safety concern for dairy industry as it is associated with incidences of food poisoning
by producing enterotoxins. In the present study, growth temperature profile and enterotoxin production
potental of 144 strains of Bacalus cereus isolated from milk and dairy products were investigated. Out of them,
107 (74.36) were able to grow at s7 oC. Presence of such a large number of psychrotolerant/psychotrophic
strains in dairy environment is of major concern mainly because of their potential for growth, spoilage and
ton production in chilled products. Out of 144 isolates, 134 (93%) exhibited haemalysis. While 98% of the
solates from milk and 899% from. cheese were positive for diarhoeal enterotoxin, all the isolates from milk
powder, ice cream, paneer and butter were positive. The prevalence of potent producers of enterotoxin among
dairy isolates pases a high health risk.
