The disclosed method simultaneously and specifically detects at least two types of food-poisoning bacteria from among Escherichia coli, Listeria, Campylobacter, Vibrio parahaemolyticus, Staphylococcus aureus, Salmonella, and Bacillus cereus. The food-poisoning bacteria detection carrier immobilizes one or at least two probes selected from each of at least two groups from among: an E. coli-detecting first probe group comprising the probes of sequence numbers 1-6 and probes (hereinafter written as "and the like") that are complementary thereto; a Listeria-detecting second probe group comprising the probes of sequence numbers 7-13, and the like; a Campylobacter-detecting third probe group comprising the probes of sequence numbers 14-19, and the like; a Vibrio parahaemolyticus-detecting fourth probe group comprising the probes of sequence numbers 20-24, and the like; a Staphylococcus aureus-detecting fifth probe group comprising the probes of sequence numbers 25-29, and the like; a Salmonella-detecting sixth probe group comprising the probes of sequence numbers 30-40, and the like; and a Bacillus cereus-detecting seventh probe group comprising the probes of sequence numbers 41-49.
