Growth, Reduction, and Survival of Bacteria on Melon Types (FSHN1207/FS191)
From 1990 to 2000, over 700 cases of foodborne illness were associated with outbreaks due to melon consumption in the U.S. and Canada. Even with efforts to educate industry and consumers of safe produce-handling practices, in the last decade there were still over 1,100 documented illnesses associated with melon consumption. This 45-page fact sheet highlights the research that has been done to provide insight on possible sanitation methods and their efficacy in decontaminating melon types of foodborne pathogens as well as natural microflora. Written by Thao P. Nguyen, Michelle D. Danyluk, and Keith R. Schneider, and published by the UF Department of Food Science and Human Nutrition, May 2012.

Growth, Reduction, and Survival of Bacteria on Tomatoes (FSHN1206/FS190)
Tomato producers are committed to taking proactive steps to ensure and enhance the safety of their fresh-market tomatoes, but even with better food safety controls, the risk for outbreaks of illness associated with tomato consumption still exists. This 32-page fact sheet highlights current tomato safety related studies on the growth, reduction, and survival of bacteria on fresh-market tomatoes. The authors evaluated bacterial studies on natural antimicrobials and detergents, as well as food processing, cross-contamination, and shelf-life studies. Written by Angela M. Valadez, Keith R. Schneider, and Michelle D. Danyluk, and published by the UF Department of Food Science and Human Nutrition, May 2012.

Citrus Diseases Exotic to Florida: Citrus Yellow Mosaic (PP293)
Citrus yellow mosaic is an important viral disease in India, where it causes significant yield reduction. In some groves, infection rate may be as high as 70%. CYMV induces a bright yellow mottling or vein flecking that persists in mature leaves. Yields are sharply reduced in chronically infected ‘Sathgudi’ sweet orange trees in India, and fruit may also show mosaic symptoms. This 2-page fact sheet was written by K.-R. Chung and R. H. Brlansky, and published by the UF Department of Plant Pathology, February 2012.

Citrus Diseases Exotic to Florida: Satsuma Dwarf (PP291)
Satsuma dwarf is a virus disease that was first reported in the early 1930s in Japan. The disease causes serious problems in citrus because it reduces tree vigor and fruit yield. Satsuma dwarf has also been reported in mandarin-growing areas in China, Korea, and Turkey, where it was likely introduced through importation of infected budwood from Japan. This 2-page fact sheet was written by K.-R. Chung and R.H. Brlansky, and published by the UF Department of Plant Pathology, February 2012.

Field Identification of Citrus Canker Symptoms and Decontamination Procedures (PP214/PP136)
Citrus canker, caused by the bacterial pathogen Xanthomonas citri subsp. citri, is a serious disease of citrus. The disease causes necrotic dieback, general tree decline, premature fruit drop, and fruit blemishes. Severely infected trees become weak, unproductive, and unprofitable. Learn how to identify citrus canker and proper procedures for decontamination with this 5-page fact sheet written by Mongi Zekri, Megan Dewdney, Jamie Yates, and Pamela Roberts, and published by the UF Department of Plant Pathology, July 2011.

Redbay Ambrosia Beetle Xyleborus glabratus Eichhoff (Insecta: Coleoptera: Curculionidae: Scolytinae) (EENY491/IN886)
Ambrosia beetles are wood-degrading insects that live in nutritional symbiosis with ambrosia fungi. Usually we consider ambrosia beetles beneficial because they accelerate the decay of dead trees, which is important for nutrient cycling in healthy forests. However, the redbay ambrosia beetle and its fungal symbiont transmit the causal pathogen of laurel wilt disease among plants in the Laurel family (Lauraceae). They are considered a “very high risk” invasive disease pest complex having potential equal to that of Dutch elm disease or chestnut blight. Laurel wilt is a relatively new disease and much is still unknown about how it will impact the flora of North America. This 7-page fact sheet highlights what we do know about this important new pest. Written by Rajinder Mann, Jiri Hulcr, Jorge Peña, and Lukasz Stelinski, and published by the UF Department of Entomology and Nematology, May 2011.
