Incidence, internalization and behavior of Salmonella in mangoes, var. Tommy Atkins

Efficacy of Chlorine, Chlorine Dioxide, and Peroxyacetic Acid in Reducing Salmonella Contamination in Wash Water and on Mangoes Under Simulated Mango Packinghouse Washing Operations

“…However, owing to the detrimental effect of high temperature on mango pulp, fruits are hydrocooled following hot water treatment (NMB, 2014). This rapid transition of warm fruit to a cooler environment has been shown to favor pathogen internalization in produce including mangoes, tomatoes, apples and oranges (Bartz and Showalter, 1980;Buchanan et al, 1999;Eblen et al, 2004;Penteado et al, 2004;Bordini et al, 2007). As previously reported, ∼2.3 log CFU/g of internalized Salmonella was recovered from the pulp of hot water treated mangoes that were hydrocooled in contaminated wash water in the absence of a disinfectant (Bordini et al, 2007;Soto et al, 2007).…”

Treatment with 5 ppm chlorine dioxide particularly in the presence of organic matter did not result in any significant reduction in internalized Salmonella populations when compared to the control.…”

Epidemiology of <i>Salmonella</i> and <i>Salmonellosis</i>

“…In areas where typhoid fever is endemic, water from lakes or rivers which are used for public consumption and are sometimes contaminated by raw sewage are the main sources of infection. The consumption of unboiled water during 1997 typhoid outbreak in Dushanbe, Tajikistan caused 2200 cases of illness and 95 deaths (Penteado and Leitão, 2004;Bordini et al, 2007).…”

“…The human health risk is increased further by Salmonella preference to grow on fresh produce during retail display at ambient temperature. In 2000, cantaloupe from Mexico resulted in a Salmonella Poona outbreak in USA (Penteado and Leitão, 2004;Bordini et al, 2007). The table below shows the prevalence of predominant Salmonella serotypes from different sources ( Table 1).…”

Effect of Soy Protein-Based Edible Coatings With Antioxidant Activity and Modified Atmosphere Packaging on the Quality of Fresh-Cut Produces

“…Human pathogens may gain entry to fruit products when animal fertilizers or contaminated irrigation water or water used for rinsing come into contact with fruits during production and processing (Brackett, 1987;Bordini et al, 2007).…”
