Risk factors for positivity to Salmonella enterica serovar Muenchen in broiler flocks by chick sampling, in study of Salmonella Muenchen in poultry and humans, Israel, 2020–2023
| Risk factor | No. positive/no. tested (%) |
Odds ratio (95% CI) | p value* | |
|---|---|---|---|---|
| First risk group | Second risk group | |||
| Breeder group, positive vs. control | 9/42 (21.4) | 9/35 (25.7) | 0.79 (0.24–2.61) | 0.658 |
| Integration member,† yes vs. no | 10/52 (19.2) | 8/25 (32) | 0.51 (0.15–1.76) | 0.215 |
| Chick age, >2 weeks vs. <2 weeks | 4/6 (66.7) | 14 /71 (19.7) | 8.14 (1.35–49.03) | 0.024 |
| Hatchery, positive or mixed vs. negative | 14/63 (22.2) | 4/14 (28.6) | 0.71 (0.17–3.62) | 0.728 |
*Calculated using Pearson χ2 test; if values to compare were <5, Fisher exact test was used. A significance level of α = 0.05 was applied. †Broiler farms contracted by a company that owns breeder farms, hatcheries, feed mills, and transportation.
