Identification of Enterobacteriaceae from washed and unwashed commercial shell eggs.
To evaluate the effect of processing on the safety and quality of retail shell eggs, a storage study was conducted with unwashed and commercially washed eggs. This work demonstrated that commercial processing decreased microbial contamination of eggshells. To know which species persisted during storage on washed or unwashed eggs, Enterobacteriaceae isolates were selected and identified biochemi...
متن کاملClassification of bacteria from commercial egg washers and washed and unwashed eggs.
A total of 432 bacterial isolates from washed and unwashed eggs, egg-washer surfaces, and washwaters from five egg-grading plants in Maryland and southeastern Pennsylvania were classified. Counts on equipment surfaces showed considerable variation from plant to plant, reflecting care used in cleaning. Unwashed eggs had a higher percentage of gram-positive cocci (71%), and isolates included Stre...
متن کاملBacterial infection of washed and unwashed eggs with reference to salmonellae.
A survey of eggs in the Fraser Valley area of British Columbia was conducted to determine the level of bacterial contamination on washed and unwashed shell eggs and the incidence of Salmonella infection in shell eggs. Samples of eggs were taken from 15 grading stations. Determinations of eggs from 87 shipments showed that a higher proportion of eggs was heavily contaminated (>5-million organism...
متن کاملRole of microbial iron transport compounds in bacterial spoilage of eggs.
Microbial iron transport compounds, belonging either to the hydroxamate family excreted by pseudomonads, or to the phenolate family excreted by salmonellae, reverse the bacteriostatic effect of conalbumin on the growth of these bacteria in egg white. The presence of microgram quantities of these compounds permits both salmonellae and pseudomonads to reach dense populations in egg white. The rol...
متن کاملSpoilage microflora of broiler carcasses washed with electrolyzed oxidizing or chlorinated water using an inside-outside bird washer.
The effect of acidic, electrolyzed oxidizing (EO) water and chlorinated water on the spoilage microflora of processed broiler carcasses was examined. Carcasses were sprayed for 5 s at 80 psi with tap, chlorinated, or EO water in an inside-outside bird washer. Treated carcasses were then stored at 4 degrees C for 0, 3, 7, or 14 d, and the microbial flora of the carcasses was sampled using the wh...
