Research – Antibacterial Effects of Phytic Acid against Foodborne Pathogens and Investigation of Its Mode of Action

Journal of Food Protection

This study investigated the antimicrobial mechanism of phytic acid (PA) and its antibacterial effects in combination with ethanol. The MIC of PA on Escherichia coli ATCC 11229, Staphylococcus aureus ATCC 6538P, Bacillus subtilis ATCC 6633, and Salmonella Typhimurium CICC 27483 were 0.24, 0.20, 0.26, and 0.28% (w/w), respectively. E. coli ATCC 11229 and S. aureus ATCC 6538P were selected to investigate the mechanism of PA by analyzing its effects at 1/2MIC and at MIC on the cell morphology, intracellular ATP, and cell membrane integrity. Environmental scanning electron microscope images revealed that PA was able to change the cell morphology and disrupt the intercellular adhesion. PA retarded bacterial growth and caused cell membrane dysfunction, which was accompanied by decreased intracellular ATP concentrations. Flow cytometry analysis further revealed that almost all the bacterial cells were damaged after treatment with PA at its MIC for 2 h. Moreover, PA has a synergistic antimicrobial ability when used in combination with ethanol. These results suggested that PA is effective in inhibiting growth of foodborne pathogens mainly by the mechanism of cell membrane damage and to provide a theoretical basis for the development of natural antimicrobial agents in the food industry.

Swedish health officials (Folkhälsomyndigheten) report investigating (computer translated) an outbreak of Yersinia enterocolitica cases throughout the country since March. Cases have been reported in nearly all regions of the country and affected adults the most.

The investigation into a foodborne source is ongoing with collaboration of the Public Health Authority, the National Food Administration, municipalities and the County Administrative Board.To date, 26 cases in ten regions have been confirmed in the outbreak. Another thirty cases are being investigated. Health officials say since the current outbreak strain of Y. enterocolitica type O3 has been found in different parts of the country, it is likely that a food borne infection will occur.

Sweden reports between 200 to 300 cases reported annually.

USA – FDA Investigating a Multistate Outbreak of Salmonella Carrau Linked to Pre-cut Melons

FDA

April 24, 2019

Pre-cut Melons

The United States Food and Drug Administration (FDA), along with the Centers for Disease Control and Prevention (CDC), and state and local partners, is investigating a multistate outbreak of Salmonella Carrau illnesses linked to pre-cut melon products.
