Campylobacter detection in 30 transport crates1: frequencies of positive crates by qualitative method, quantification by most probable number (MPN) method (log10 MNP/g), and overall or pooled MPN, according to the stage of cleaning and disinfection processes.
| Stage of cleaning and disinfection processes | Frequencies of Campylobacter detection % (n/N)2 |
Quantification of Campylobacter (log10 MPN/g)3 mean ± standard-deviation |
Overall or pooled MPN (MPN/g)4 |
|---|---|---|---|
| before the cleaning and disinfection processes | 63 (19/30)a | 0.81 ± 0.89a | 40.13 |
| after the cleaning and disinfection processes | 70 (21/30)a | 0.70 ± 0.77ab | 24.12 |
| after 24 hours of natural drying | 46 (14/30)a | 0.30 ± 0.57b | 5.79 |
1
Three transport crates of each flock, totaling 30 crates evaluated in this study.
ab
Different letters in the same column represent significant differences among stages of cleaning and disinfection processes.
2
Fisher's exact test (adjusted P-value = 0.0169).
3
One-way ANOVA, followed by Tukey's Honestly Significant Difference (HSD) test (P < 0.05).
