Abstract
The behavior of thirteen foodborne bacteria onto whole Hass avocado and the antibacterial effect of Hibiscus sabdariffa calyx extracts, sodium hypochlorite, acetic acid, and colloidal silver against foodborne bacteria on contaminated avocado were investigated. Avocados were inoculated with foodborne bacteria: Listeria monocytogenes, Shigella flexneri, Staphylococcus aureus, Salmonella Typhimurium, S. Typhi, S. Montevideo, Escherichia coli O157:H7, non-O157:H7-Shiga toxin-producing E. coli, enteropathogenic E. coli, enterotoxigenic E. coli, enteroinvasive E. coli, enteroaggregative E. coli, and Vibrio cholerae O1. The antibacterial effect of four roselle calyx extracts (water, methanol, acetone, and ethyl acetate), sodium hypochlorite, colloidal silver, and acetic acid against all foodborne bacteria were examined onto avocados. All foodborne bacteria successfully attached and survived onto avocado at least 20 days. The acetonic and methanolic roselle extracts caused a greater reduction (until 4-log10 in some cases) in the concentration of all foodborne bacteria than sodium hypochlorite, colloidal silver, and acetic acid on contaminated avocados.
