Summary: | Increased consumption, big production units and very efficient delivery
service networks of fresh vegetables and salads caused a higher number of
foodborne illnesses in the last two decades all over the world. In this
study 15 fresh vegetable salads from different marketplaces in Novi Sad were
tested by reference microbiological methods (detection of Salmonella spp.,
enumeration of Listeria monocytogenes, mesophilic aerobic bacteria, yeasts
and molds, sporogenic mesophilic aerobic bacteria, sporogenic
sulfite-reducing bacteria, Bacillus cereus, Enterobacteriaceae, Escherichia
coli and coagulase positive staphylococci). Salmonella spp. was found in one
sample which, according to the safety criteria for such a product (if
treated as ready-to-eat), was considered to be microbiologically unsafe. The
number of Listeria monocytogenes in all tested samples was <100 cfu/g, which
is a satisfactory result according to the safety criteria. E. coli was
detected in only one sample, and the number of Enterobacteriaceae was in the
range from 4.4 to 6.9 log CFU/g. The isolated Enterobacteriaceae strains
were identified as Enterobacter cloacae, Klebsiella pneumoniae ssp.
pneumoniae and Citrobacter spp. |
