Outbreaks of Escherichia coli O157:H7 and Salmonella infections linked to consumption of unpasteurized fruit juices have been reported. Apples spot-inoculated with E. coli O157:H7 and Salmonella Muenchen were treated with ...
Caenorhabditis elegans as a model for free-living nematodes in vectoring human pathogenic bacteria to fruits and vegetables
A microbivorous free-living nematode, Caenorhabditis elegans, was studied to determine its potential role as a vector for preharvest contamination of fruits and vegetables. Propensity of the nematode to be attracted to ...
Mechanical abrasion with subsequent spray applications of sanitizer as a method to remove biofilms and non-biofilms from food processing surfaces
The attachment and potential growth of bacteria remaining on food processing equipment after sanitation can cause cross-contamination, which can lead to food spoilage and possible food safety concerns. The purpose of this ...
Pathogen inactivation on beef jerky in a commercial-type dehydrator under various moisture conditions
A small commercial-type dehydrator was modified to add steam during the processing of whole muscle beef jerky. The incoming air’s relative humidity was decreased to15 %- 20% by using a home dehumidifier. Two processing ...
