The present systems for cleaning the plastic crates (drawers) used to transport live poultry to the processing plant are known to be inadequate for removing microbial contamination. 2. To investigate possible improvements, a mobile experimental rig was constructed and operated in the lairage of a poultry processing plant. The cleaning rig could simulate the conditions of commercial cleaning systems and utilise freshly emptied crates from the processing plant. 3. The aim of the study was to improve cleaning by enhancing the removal of adherent organic material on the crates and by reducing microbial contamination by at least 4 log10 units. 4. Trials showed that the most effective treatments against Campylobacter was either (a) the combination of soaking at 55oC, brushing for 90 s, washing for 15 s at 60oC, followed by the application of disinfectant (Virkon S in this study) or (b) the use of ultrasound (4 kW) at 65oC for 3 – 6 min, with or without mechanical brushing of crates. 5. Both of these treatments also achieved a 4-log10 reduction or more in the counts of Enterobacteriaceae but were less effective in reducing aerobic plate counts. 6. It was noted that here was little correlation between the visual assessment of crate cleanliness and microbiological counts. 7. It was concluded that the demonstrated enhanced cleaning could contribute significantly to overall hygiene control in poultrymeat production.
