Fecal Coliform Bacteria in Vegetable Salads Prepared in Baghdad Restaurants
Bibliographic record
Abstract
This study aimed to evaluate the presence of coliforms in 50 samples (25 ready-to-eat vegetable salads and 25 handlers’ hands) collected randomly from restaurants in Baghdad. The total coliform count in the samples of vegetable salads from Al-Sadria and Hay al-Amel reached 4.78 and 4.32 log cfu/g, respectively, whereas those in the swab samples of handlers’ hands from the same areas reached 3.70 and 3.90 log cfu/g, respectively. The percentages of fecal coliform bacteria in the salad samples from Al-Sadria and Hay al-Amel were 35% and 32%, respectively, whereas those in the hand swabs from the same areas were 41% and 36%, respectively. Two isolates of the serotype Escherichia coli O157:H7 were detected in the study samples from the same areas, where the rates of E. coli and fecal coliform bacteria increased. Considering the virulence of this bacterial serotype and its direct impact on consumer safety, we highly recommend implementing quality programs in ready-to-eat vegetable salad production chains, raising the cultural level and health awareness of restaurant owners and workers preparing these salads, and raising public awareness of the potential health risks of consuming contaminated food products.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
