This research investigates the efficacy of gaseous ozone, applied under partial vacuum in a controlled reaction chamber, for the elimination of Salmonella inoculated on melon rind. The performance of high dose, short duration treatment with gaseous ozone, in this pilot system, on the microbial and sensory quality of fresh-cut cantaloupes was also evaluated. Gaseous ozone (10,000 ppm for 30 min ...

Labor, Landscape, and Four Virginia Watermen Jessica Taylor (bio) Patrick Daglaris In Mathews County, Virginia, men crab, oyster, fish in workboats or sail on commercial vessels. They leave home hemmed by 350 miles of shoreline, tidal wetlands, stands pine trees jutting into the water, small, brushy islands at a distance haze. On shore, fewer than nine thousand people live many them retirees se...

Fruit ripening and abscission are associated with an ethylene burst in several melon (Cucumis melo) genotypes. In cantaloupe as in other climacteric fruit, exogenous ethylene can prematurely induce abscission, ethylene production, and ripening. Melon genotypes without fruit abscission or without ethylene burst also exist and are, therefore, non-climacteric. In the nonabscising melon fruit PI 16...

The advantages and disadvantages of subsurface drip irrigation (SDI) as compared to alternative irrigation systems are conceptually discussed. Each category (advantages and disadvantages) is subdivided into three groups: 1) Water and soil issues; 2) Cropping and cultural practices, and 3) System infrastructure issues. The adaptation and adoption of SDI systems into diverse cropping systems, geo...

Recent outbreaks linked to Salmonella-contaminated produce heightened the need to develop simple, rapid, and accurate detection methods, particularly those capable of determining cell viability. In this study, we examined a novel strategy for the rapid detection and quantification of viable salmonellae in produce by coupling a simple propidium monoazide sample treatment with loop-mediated isoth...

nutrient totals, not the contents of the recipe or menu, are saved; this limitation may necessitate keeping a printout that defines the menu or recipe. An additional limitation of this program is that, while the original and especially the expanded database are large, both lack common products and both should be more specific. For example, products containing Nutrasweet are not included; cucumb...

Typhoid is a severe, contagious and life-threatening disease associated with fever that is most often caused by the typhoid bacillus, Salmonella enterica, serovar Typhus. Typhoid fever is transmitted by ingestion of food, including dairy products, or water contaminated by excreta from patients or chronic by infected persons. It mostly affects school-age children. In adults and older people, typ...

To the Editor: The oral allergy syndrome (OAS) describes an allergic reaction that occurs on ingestion of certain fresh fruits and vegetables in pollen-sensitized subjects. The culprit allergens found in associated fresh foods are rapidly inactivated by digestion and cooking. As a result, symptoms are usually limited to the mouth and throat and preferably observed with raw forms of the food. Wh...

ABSTRACT Polygalacturonase-inhibiting proteins (PGIPs) are believed to aid in plant defense against fungal pathogens by inhibiting polygalacturonases (PGs) secreted by the invading organism. In an effort to better understand this type of plant-pathogen interaction in cucurbits, we have isolated a cantaloupe PGIP (CmPGIP) from 5 to 15 day postanthesis cantaloupe fruit. CmPGIP inhibited crude ext...
