Abstract

 
The study was conducted to determine the survival time of the local field Brucella melitensis biovar 3 and Br. melitensis 16M (standard strain) in butter held at 4°C and ice cream stored at subfreezing temperature (-22 C). Local field Br. melitensis biovar 3 survived for 26 and 42 days in farm (cooking) and table imported butters, respectively. While, Br. melitensis 16 M strain died after 20 and 38 days in both types of butters, respectively. In both types of ice cream (pre-and post-manufacture infected) stored at subfreezing temperature, the local field Br. melitensis biovar 3 and 16 M strains were found viable for 14 and 8 weeks, respectively. The public health significance of the organism was discussed
