| E. coli class | Water (log E. coli CFU/100 ml) | Strawberries and substrate (log E. coli CFU/g) | Hands (log E. coli CFU/25 cm2) | Plastic foil on soil (log E. coli CFU/3000 cm2) |
|---|---|---|---|---|
| 1 (= undetected) | <0.0 | <1.0 | <0.7 | <2.6 |
| 2 | ≥0.0 and <1.0 | ≥1.0 | ≥0.7 | ≥2.6 |
| 3 | ≥1.0 and <2.0 | NAa | NA | NA |
| 4 | ≥2.0 and <3.0 | NA | NA | NA |
| 5 | ≥3.0 | NA | NA | NA |
