Food Safety Education For Students And Workers In School Gardens And University Farms, John Dzubak, Angela Shaw, Catherine Strohbehn, Linda Naeve Feb 2016

Food Safety Education For Students And Workers In School Gardens And University Farms, John Dzubak, Angela Shaw, Catherine Strohbehn, Linda Naeve

Food Science and Human Nutrition Publications

The number of school gardens and university farms is increasing in the United States. Produce grown in these venues is often sampled in the classroom or incorporated into the food chain. Food safety education for students and workers is needed to ensure that produce is safe. Two 1-hr food safety curricula were developed to inform K–12 students and university farm researchers and workers about good agricultural practices. The validated curricula include four or five short video modules, activities, instructor/facilitator lesson plans, knowledge assessment quizzes, and instructor manuals. Piloting results indicated that participants increased food safety knowledge after viewing ...

Combination Of Adhesive-Tape-Based Sampling And Fluorescence In Situ Hybridization For Rapid Detection Of Salmonella On Fresh Produce, Bledar Bisha, Byron F. Brehm-Stecher Oct 2010

Combination Of Adhesive-Tape-Based Sampling And Fluorescence In Situ Hybridization For Rapid Detection Of Salmonella On Fresh Produce, Bledar Bisha, Byron F. Brehm-Stecher

Food Science and Human Nutrition Publications

This protocol describes a simple approach for adhesive-tape-based sampling of tomato and other fresh produce surfaces, followed by on-tape fluorescence in situ hybridization (FISH) for rapid culture-independent detection of Salmonella spp. Cell-charged tapes can also be placed facedown on selective agar for solid-phase enrichment prior to detection. Alternatively, low-volume liquid enrichments (liquid surface miniculture) can be performed on the surface of the tape in non-selective broth, followed by FISH and analysis via flow cytometry. To begin, sterile adhesive tape is brought into contact with fresh produce, gentle pressure is applied, and the tape is removed, physically extracting microbes present on ...
