| Type of vegetable | Contamination rate (%)a | MPN value (MPN/g)b |
||
|---|---|---|---|---|
| MPN < 3 (%) | 3 ≤ MPN < 1100 (%) | 1100 ≤ MPN (%) | ||
| Coriandrum sativum L | 56/89 (62.92) | 1/56 (1.79) | 38/56 (67.86) | 17/56 (30.36) |
| var. ramosa Hort. | 49/85 (57.65) | 5/49 (10.20) | 41/49 (83.67) | 3/49 (6.12) |
| Cucumis sativus L. | 63/134 (47.01) | 12/63 (19.05) | 50/63 (79.37) | 1/63 (1.59) |
| Lycopersicon esculentum Mill. | 43/111 (38.74) | 19/43 (44.19) | 24/43 (55.81) | 0/43 (0.00) |
| Total | 211/419 (50.36) | 37/211 (17.54) | 153/211 (72.51) | 21/211 (9.95) |
aContamination rate = number of positive samples/total samples. bMPN value (MPN/g) = most probable number of B. cereus per gram sample.
