Antibiotic-resistant Salmonella strains were isolated from saladette and red round type tomatoes, an analysis done of the antibacterial activity roselle calyx extracts against any identified strains. One hundred tomato samples 100 collected public markets. Each sample consisted four whole tomatoes. was by conventional culture procedure. Susceptibility to 16 antibiotics tested for standard test. The effect (water, methanol, acetone ethyl acetate), sodium hypochlorite acetic acid antibiotic-resistant isolates evaluated on contaminated Twenty-four 12% each type. Identified serotypes Typhimurium Typhi. All exhibited resistance at least three some as many 12. Over produced a greater reduction (2-2·6 log) in strain concentration than acid.The presence multidrug-resistant vegetables is significant health concern. Multidrug-resistant raw tomatoes purchased markets Mexico challenged with Hibiscus sabdariffa extracts, acid. On caused Roselle are potentially useful addition disinfection procedures field, processing plants, restaurants homes.
