Figures
- FIG 1
Conceptual overview of process to implement hygiene management.
- FIG 2
ATP swab failure rate over time. Trend lines are locally fitted polynomial regressions computed via the LOESS method, grouped by zone. Vertical lines correspond to the separation of the three phases utilized in this study (phase 1, preintervention—30 sites targeted per day [21 zone 1 and 9 zone 2]; phase 2, postintervention—30 sites targeted per day [21 zone 1 and 9 zone 2]; and phase 3, postintervention—18 randomized sites targeted per day [12 zone 1 and 6 zone 2]).
- FIG 3
Proportion of swabs, aggregated by zone, failing to meet the minimum sanitary requirements based on the measurement of ATP, yeasts and molds (RYM), lactic acid bacteria (LAB), and aerobic microorganisms (RAC) during phases 1 and 3. Error bars represent the 95% confidence interval for each group based on the binomial distribution. Asterisks correspond to a significant difference between phases for a given zone (P < 0.001, Fisher’s exact test).
- FIG 4
Microbial load of yeasts and mold (RYM), lactic acid bacteria (LAB), and aerobic microorganisms (RAC) in packaged tofu products sampled prepasteurization. Red lines correspond to the limits of detection for each group of interest. Numbers correspond to the P value between phases 1 and 3.
- FIG 5
Microbial load of yeasts and mold (RYM), lactic acid bacteria (LAB), and aerobic microorganisms (RAC) in packaged tofu products sampled postpasteurization. Red lines correspond to the limits of detection for each group of interest. Numbers correspond to the P value between phases 1 and 3.
