Enteric Pathogen Survival Varies Substantially in Irrigation Water from Belgian Lettuce Producers
It is accepted that irrigation water is a potential carrier of enteric pathogens, such as Salmonella and E. coli O157:H7 and, therefore, a source for contamination of fresh produce. We tested this by comparing irrigation water samples taken from five different greenhouses in Belgium. The water samples were inoculated with four zoonotic strains, two Salmonella and two E. coli O157:H7 strains, an...
متن کاملSurvival of enteric pathogens during butterhead lettuce growth: crop stage, leaf age, and irrigation.
The survival of Salmonella enterica serovar Thompson and Escherichia coli O157 was investigated on growing butterhead lettuce plants in the plant-growth chamber and greenhouse. All inoculation tests were made under conditions that approximate the greenhouse conditions for butterhead lettuce cultivation in Flanders (Belgium). The survival and proliferation of the pathogens on the leaves was dete...
متن کاملModerate prevalence of antimicrobial resistance in Escherichia coli isolates from lettuce, irrigation water, and soil.
Fresh produce is known to carry nonpathogenic epiphytic microorganisms. During agricultural production and harvesting, leafy greens can become contaminated with antibiotic-resistant pathogens or commensals from animal and human sources. As lettuce does not undergo any inactivation or preservation treatment during processing, consumers may be exposed directly to all of the (resistant) bacteria p...
متن کاملPredicting perchlorate uptake in greenhouse lettuce from perchlorate, nitrate, and chloride irrigation water concentrations.
Perchlorate (ClO) has been detected in edible leafy vegetables irrigated with Colorado River water. The primary concern has been the ClO concentration in lettuce ( L. var. L.). There has been a limited number of studies on ClO uptake, but the interactive effect of other anions on ClO uptake is not known in detail. We conducted a greenhouse ClO uptake experiment using two types of lettuce (icebe...
متن کاملOccurrence and Antimicrobial Resistance of Enterococcus spp. Isolated from Lettuce and Irrigation Water in Abidjan, Côte d\'Ivoire
Background: Enterococcus spp., belonging to the group of lactic acid bacteria, are Gram-positive ubiquitous commensals of the intestines of human beings as well as warm-blooded animals. The main objective of this study was to determine the occurrence and antimicrobial resistance of Enterococcus spp. isolated from lettuce and irrigation water in Abidjan, Côte d'Ivoire. Methods: A total of...
