Levels of AFM1 in raw milk samples collected from four divisional regions.
| Regions | n | Positive Sample n (%) |
Mean ±SD (ng/L) |
Median (Range) (ng/L) |
Above 50 ng/L n (%) |
|---|---|---|---|---|---|
| Sylhet | 40 | 34 (85) | 53.7 ± 51.0 | 34.0 (5.5–198.7) | 13 (32.5) |
| Dhaka | 25 | 15 (60) | 37.8 ± 29.2 | 33.2 (5.1–97.2) | 7 (28.0) |
| Chittagong | 20 | 8 (40) | 6.6 ± 1.9 * | 5.8 (5.0–10.6) | 0 (0) |
| Rajshahi | 20 | 18 (90) | 34.8 ± 39.1 | 19.2 (6.3–131.4) | 5 (25) |
| Total | 105 | 75 (71.4) | 41.0 ± 43.4 | 23.5 (5.0–198.7) | 25 (23.8) |
Only positive samples (≥LOD: 5 ng/L) were considered during mean and median calculation. * When comparing mean AFM1 concentration to Sylhet (p < 0.001), Dhaka (p < 0.01) and Rajshahi (p < 0.05) regions. p-values were obtained from one-way ANOVA.
