The safety of wooden cutting boards -: Remobilization of bacteria from pine, beech, and polyethylene

Purpose - This study aims to compare the aptitude of pine as a softwood and beech as a hardwood, regarding their different retention and antimicrobial performances as compared to polyethylene. Design/methodology/approach - Four sets of tests were carried out: recovery, cleaning, remobilization and survival experiments. For all experiments wood and control blocks or chippings were spiked with bacteria and tested at set intervals for bacterial counts using standard procedures. Findings - Overall, wood performed at least as good as polyethylene. Polyethylene is not as easy to clean. The problematic cleansing capabilities of wood are compensated by its open structure. Pine exerted antimicrobial abilities faster than beech and showed better performance than both beech and polyethylene. The differences between beech and polyethylene were only marginal. Research limitations/implications - The findings may help along with further research to re-establish the value of wood in some food processing settings and in the home. However, only new materials were used so that no statement on the performance of used wood and plastic utensils can be made. Besides, only two types of woods and one type of plastic were used in this study. Originality/value - This article is written with the expertise of the authors and will be of interest to those in the field.
