Contribucion de las practicas de produccion de cultivos y las condiciones climaticas a la seguridad microbiologica de los tomates y pimientos

Figure 1. Tomato plants in the field at the UF/IFAS Research and Education Center in Citra, Florida, are subjected to different irrigation and fertilization regimens.Durante la última década, las frutas, verduras y frutos secos se encuentran entre los alimentos relacionados con brotes de gastroenteritis causadas por cepas enterovirulentas de E. coli y Salmonella no tifoidea que resultan en miles de hospitalizaciones y pérdidas de varios millones de dólares en la industria de alimentos (Mandrell 2009; Batz, Hoffman, y Morris 2011). Desde 2006, dieciséis brotes de salmonelosis se han relacionado con el consumo de frutas y verduras, incluyendo tomates, melones, coles, pepinos, mangos, piñones, pistachos, mantequilla de maní, papayas, pimientos y además alimentos congelados y procesados que contienen productos vegetales. Esta hoja informativa fue producida para proveer información actualizada sobre las prácticas de producción de tomate y sus asociaciones con Salmonella. Esta información es útil para Agentes de Extensión Agraria en sus programas de educación sobre cultivos hortícolas.

Tomatoes of different varieties at different maturity stages are cued for testing for their resistance to SalmonellaDe 1998 a 2007 la fruta fresca, verdura, especias y nueces fueron comúnmente asociados con brotes de gastroenteritis (Batz, Hoffman, y Morris 2011). Salmonella se ha convertido en uno de los patógenos humanos más problemáticos asociado a productos frescos, nueces y a los alimentos que contienen esos ingredientes (Batz, Hoffman, y Morris 2011; deWaal, Tian, y Plunkett 2009).

Control of Rapid Postharvest Decays of Tomato Fruit

Figure 11. Fruit picked during a rain shower and then dye added to wet stem scar. What is a rapid postharvest decay? Water-soaked lesions begin within 12 to 18 hours after harvest and continue to develop, producing large amounts of fluids. The decay spreads within cartons of tomatoes, producing wet patches in the bottom and sides of the container, a condition called “wet-boxes.” Affected fruit are out-of-grade either prior to shipment or upon arrival at the receiver.This 5-page fact sheet was written by J. A. Bartz, S. A. Sargent, and D. J. Huber, and published by the UF Department of Horticultural Sciences, December 2014. (Photo: S. R. Bartz)

The role of crop production practices and weather conditions in microbiological safety of tomatoes and peppers

Figure 1. Tomato plants in the field at the UF/IFAS Research and Education Center in Citra, Florida, are subjected to different irrigation and fertilization regimens.Salmonella and other human pathogens can contaminate produce at any stage from “farm to fork.” If we can better understand how production practices may make crops more or less susceptible to human pathogens we may be able to significantly reduce the number and severity of the produce-associated outbreaks. This 3-page fact sheet provides up-to-date information about tomato production practices and their relationships with Salmonella.

Impact of Tomato Varieties and Maturity State on Susceptibility of Tomatoes to Salmonella

Figure 1. Tomatoes of different varieties at different maturity stages are cued for testing for their resistance to SalmonellaNon-typhoidal Salmonella has emerged as one of the problematic human pathogens associated with fresh produce, nuts, and complex foods containing them. Recent research shows that some varieties of plants are more “resistant” to colonization by the pathogens than others. This raises the intriguing possibility that cultivar selection could be used to identify crop varieties that may be less conducive to proliferation of human pathogens.

Solutions for Managing Tomato Culls in Florida Tomato Packinghouses (SL371/SS572)

tomatoes in cratesFlorida is the single largest producer of fresh-market tomatoes in the United States. Driven by urbanization and generation of large amounts of tomato culls, tomato packers in Florida often struggle to find ways to dispose of culls generated during the cleaning and sanitizing of tomatoes. This 5-page fact sheet provides guidelines for appropriate management practices to increase the use of culls produced in tomato packinghouses in Florida. Written by Gurpal Toor, Maninder Chahal, and Bielinski Santos, and published by the UF Department of Soil and Water Science, September 2012.

Solutions for Managing Wastewater in Florida Tomato Packinghouses (SL372/SS573)

splashing tomatoA large amount of wastewater is produced in Florida's packinghouses during the cleaning and sanitizing of tomatoes. High transportation costs for off-site disposal and strict surface water discharge regulations are critical issues associated with the management of this wastewater. This 4-page fact sheet provides solutions for increasing the reuse of wastewater in tomato packinghouses in Florida. Written by Gurpal Toor, Maninder Chahal, and Bielinski Santos, and published by the UF Department of Soil and Water Science, August 2012.

Postharvest Quality and Decay Incidence among Tomato Fruit as Affected by Weather and Cultural Practices. (PP294)

Figure 11. Concentric cracking of fruit surface.Postharvest decay losses for field-grown, fresh-market tomatoes are usually associated with harvests that occur when fields are wet and warm. During periods of persistently wet fields, decay pathogens infect damaged fruit on the plant as well as injuries to petioles and stems. Review of all reports and photos implicated excessive water in fruit rather than air temperatures as the primary predisposition. Excessive water in fruit is possible at virtually any time of the season and can appear at times of cold as well as warm field temperatures. This 8-page fact sheet was written by Jerry A. Bartz, Steven A. Sargent, and John W. Scott, and published by the UF Department of Plant Pathology, July 2012.
