Two days after a catered event, the health department calls to say several guests have laboratory-confirmed Salmonella. What is the manager's best first step in the outbreak response?

解析

In a suspected foodborne-illness outbreak, the manager should cooperate fully with the regulatory authority, set aside and label any suspect food so it can be tested, and preserve production and employee-health records. Denying a connection before the records have been reviewed states a conclusion the operation has not yet earned, discarding the suspect food and the logs destroys the evidence the investigation depends on, and silencing staff while the same menu keeps going out leaves the public exposed. Early, honest cooperation protects the public and the business.
