Bacteriological Quality Assessment of some Yoghurt Brands Sold in Kaduna Metropolis
Bibliographic record
Abstract
The bacteriological quality of some processed yoghurt on sale at different sale outlets within Kaduna metropolis was assessed. Twenty samples of different brands were purchased and analysed in the laboratory for pH, aerobic-mesophilic count, coliform count and staphylococcal count. The pH ranged from 3.9 to 4.5.Seventeen of the samples recorded growth in the range of 2.0 x 10 2 to 7.0 x 10 3 cfu/ml for aerobic mesophilic count while a range of 1.0 x 10 2 to 4.0 x 10 3 and 1.0 x 10 2 to 4.0 x 10 3 cfu/ml for staphylococcal count and coliform count respectively. No growth was recorded in three samples. After biochemical characterization, Staphylococcus aureus and Escherichia coli were the predominant bacteria isolated. The presence of coliforms is an indication of faecal contamination of the product. Keywords: Bacteria, quality assessment, yoghurt, aerobic Count.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
