The enumeration of B. cereus, total coliforms, Pseudomonas spp., S. aureus, TVC, and YMC on experimental carrot treatments during storage is shown in Fig. 5. Results showed that the application of chitosan coatings caused a reduction in microbial loadings on treated carrots. Throughout the entire storage period, all carrot samples showed a complete absence of E. coli. Similarly, S. aureus was absent until the latter days of product storage. The values for B. cereus increased gradually for control samples, whereas they remained at a constant level for coated samples showing values of around 5.5 log CFU/g sample. The antimicrobial activity of chitosan-based coatings against coliforms was remarkable throughout the experimental storage period. Something similar occurred in the case of Pseudomonas spp., although the growth of this microorganism increased as storage time progressed. Coated samples exhibited lower microbial loads than control samples over the experimental storage period.
