The Effect of Microwaves on the Survivability of Brucella Microorganisms in Infected Cattle Milk - Juniper Publishers
Journal of Dairy & Veterinary Sciences - Juniper publishers Abstract This study was carried out to investigate the effect of microwave radiation on the viability of Brucella melitensis in contaminated cattle milk through establishing a correlation between milk volumes, microwave exposure time, measured Celsius temperature and viable counts of B. melitensis in inoculated milk. Microwave appliances were used in houses and many food stores in Egyptand worldwide, for warming milk that processed for human consumption. Microwave heating was performed using a household electronic microwave oven (Kenwood MW 579, a frequency of 2,450 MHz, and power of 900W). Brucella-free milk is inoculated with B. melitensis in a dose of (1.3 X 108 CFU / ml) and samples are divided into 100 ml and 200 ml volumes and maintained at room temperature (22 °C ± 3°C) or refrigeration temperature (5 ºC ± 2 ºC) prior to microwave exposure. Microwave radiations with full power (P = 100) eliminate B. melitensis...
