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 کاملHuman ventilatory response to washed and unwashed cottons from different growing areas.
Thirty volunteer subjects were exposed to controlled amounts of respirable dust generated by the carding of cotton in an experimental cardroom. Eighteen exposures each lasting six hours were performed while carding unwashed and washed cottons from the three major growing regions of the United States. Elutriated dust was analysed gravimetrically and was comparable (0.59 mg/m3 +/- 0.04) for all e...
متن کاملVariations in external and internal microbial populations in shell eggs during extended storage.
The current project was conducted to determine the microbial quality of commercially processed shell eggs during extended storage. Unwashed eggs were collected at the accumulator before entering the processing line. Washed eggs were retrieved after placement in flats. All eggs were stored on pulp flats at 4 degrees C for 10 weeks. Twelve eggs from each treatment were rinsed on the day of collec...
