A plurality of probes are immobilized on a carrier for detecting food poisoning bacteria, the plurality of probes being selected, either alone or in combination, respectively from two or more groups among a first probe group for detecting Escherichia coli, a second probe group for detecting Listeria, a third probe group for detecting Campylobacter, a fourth probe group for detecting Vibrio parahaemolyticus, a fifth probe group for detecting Staphylococcus aureus, a sixth probe group for detecting Salmonella, and a seventh probe group for detecting Bacillus cereus. Two or more types of food poisoning bacteria among Escherichia coli, Listeria, Campylobacter, Vibrio parahaemolyticus, Staphylococcus aureus, Salmonella, and Bacillus cereus can be specifically and simultaneously detected using the carrier.
