“…COD levels higher than 800 mg O 2 /L can be considered high based on the previously published recommended guidelines and legislation, where values above 500 mg/L have been defined between moderate to high (Mujeriego, 1990;USEPA, 2004). Previous reported COD values for irrigation water (ranged between 15 and 107 mg O 2 /L) were significantly lower than the COD values found in the present study (Gemmell & Schmidt, 2012;Ijabadeniyi, Debusho, Vanderlinde, & Buys, 2011). The average alkalinity value was 9.4 ± 1.2 meq HCO 3 − /L.…”

“…Increasing consumption of fresh produce has associated outbreaks of foodborne illnesses [5,12,13]. Fresh produce can be a vehicle for the contamination of enterotoxigenic and enterohemorrhagic Escherichia coli [1,10,[14][15][16], Salmonella spp. [1,14,17], Listeria monocytogenes [1,17,18,19], thermotolerant Campylobacter spp.…”

Abstract:Two hundred sixty one samples, collected from supermarkets in Istanbul, Turkey. All samples were analysed for aerobic mesophilic bacterial counts (AMC), aerobic psychrotrophic bacterial counts (APC), enumeration of yeasts and moulds (YM), coliforms, Escherichia coli and detection of Escherichia coli O157:H7, Salmonella spp., Listeria monocytogenes, thermotolerant Campylobacter spp. AMC ranged from 2.95 to 3.75 log 10 CFU/g. APC ranged from 0 to 3.55 log 10 CFU/g. The highest counts of coliforms were found in carrot, spinach, green leaf lettuce, cos lettuce and iceberg lettuce. The highest counts of YM were found in tomato, spinach, green leaf lettuce, cos lettuce and iceberg lettuce. Green leaf lettuces, cos lettuces, iceberg lettuces, spinach and carrot were highly contaminated with aerobic mesophilic (3.6 log 10 CFU/g), psychrotrophic microorganisms (3.4 log 10 CFU/g), and showed a high incidence of E.coli (41.77% of samples). Of the samples analysed, 10 (3.83%) were Salmonella spp. positive and 17 (6.51%) were thermotolerant Campylobacter spp. positive. None of the samples was positive for Escherichia coli O157:H7 and Listeria monocytogenes. Fresh vegetables and fruits, sold in Istanbul, Turkey, are needed to control foodborne pathogens especially Salmonellosis and Campylobacteriosis.

“…Globally, agricultural water has been recognised as one of the most important potential preharvest source of produce contamination by foodborne pathogens (Gemmell & Schmidt, 2012;Ijabadeniyi et al, 2012;Pachepsky et al, 2011).…”

Prevalence and serovar diversity of Salmonella spp. in primary horticultural fruit production environments

2016

View full text Add to dashboard Cite

Increases in foodborne disease outbreaks associated with fresh produce have necessitated the need to identify potential sources of microbial contamination in produce and agricultural environments. The present study evaluated Salmonella prevalence and serovar diversity in show the potential of agricultural fruit production environments to act as reservoirs of clinically important Salmonella serovars.
