Interpretive summary: Listeria monocytogenes and Salmonella spp. are major foodborne pathogens. This study was conducted to evaluate the efficacy of extracts from four different blueberry cultivars against L. monocytogenes and S. Enteritidis and determine the inhibitory and bactericidal concentrations. Result showed that blueberry extracts at 112-900 mg/mL displayed significant antimicrobial activities and were more effective against L. monocytogenes than S. Enteritidis. Chlorogenic acid, ellagic acid, and quercetin-3-galactoside were identified as the antimicrobial compounds in the extracts. This study demonstrates that blueberry extract may be used in food products to improve microbiological quality.
