bacteria in fresh vegetables from different locations such as local shops and superstores. Total
108 samples were collected 9 from each place. Samples collected carefully in sterilized bags and
processed in microbiological lab of UVAS Lahore.
Fresh vegetables are an important part of our daily food and especially fresh vegetables
with less processing like lettuce, carrot and beet root which are used as raw without cooking;
such type of vegetables became the cause of illness because of the microbial/cross
contamination. It is alarming situation for suitable agency to take some necessary action, make
guidelines to prevent potential food borne illnesses from the vegetables that contain pathogenic
bacteria, and find natural antimicrobials from plants that control spoilage and pathogenic
microorganisms in vegetables. Microbial quality of vegetables is not in good condition.
The vegetable samples were divided into two categories local shops and superstores.
Total six local shops and six superstores were selected for the collection of samples in triplicate
pattern. All the samples were evaluated for microbial parameters,Like TPC, TCC, detection of
salmonella ,E coli and staphylococcus aureus.
Data was analysed statistically by the two- way ANOVA (Analysis of Variance) for
microbial count with 5% probability. Means were compared by LSD (least significant design)
test (Steel et al.1997).
The aim of present study is to provide awareness and microbial trend data about different
fresh vegetables sold in North-West Lahore.Results of current study shows that the
microbiological quality of fresh vegetables collected from superstores is better than the local
Summary
62
shops. The result of present study shows that consumers should prefer to buy vegetables from
superstores as compared to local shops because the keeping quality and handling practices are
good in superstores than local shops.
