Abstract
Escherichia coli is one of the most important food-borne pathogens of public health interest worldwide. The analysis of E. coli in the food industry is both costly and time-consuming. The autofluorescence spectra of chicken meat submitted to E. coli contamination and stored at 4 degrees C and 25 degrees C were measured by fluorescence spectroscopy. The change of intrinsic meat fluorophores contents was studied with excitation at 340 and 410 nm, as a function of the storage time to detect the meat spoilage status. The obtained results showed changes in meat fluorophores emissions intensities mainly related to microbial metabolism, indicating that fluorescence could be considered as an emerging new alternative to identify E. coli contamination in meat.
