Section 690.565 Outbreaks of Public Health Significance (Including, but Not Limited to, Foodborne or Waterborne Outbreaks) (Reportable by telephone or electronically as soon as possible, within 24 hours)
a) Investigation of Outbreaks
1) Any pattern of cases, or increased incidence of any illness beyond the expected number of cases in a given period, that may indicate an outbreak, including suspect or confirmed outbreaks of foodborne or waterborne disease, or outbreaks transmitted by laboratory acquisition, animal contact, person-to-person contact, inhalation or other transmission method, shall be reported to the local health authority within 24 hours. This includes, but is not limited to, outbreaks of gastroenteritis and group A streptococcal disease (including invasive infections, necrotizing fasciitis, and toxic shock syndrome).
2) All suspect or confirmed foodborne outbreaks shall be investigated by the local health authority where the food was prepared. If multiple jurisdictions are involved, the jurisdiction where the food was prepared shall be in charge of the investigation unless determined otherwise. All suspect or confirmed outbreaks not caused by foodborne transmission shall be investigated by the local health authority where the exposure occurred.
3) If the investigation determines that an outbreak has occurred, the jurisdiction in charge of the investigation shall submit a final report to the Department, using the most current outbreak reporting form available from the Department, within four weeks following the completion of the epidemiologic investigation.
4) When outbreaks occur in any business, organization, institution, private home or health care facility, staff in the establishment where the outbreak occurred may be considered to be contacts to cases and may be required by the local health authority to submit specimens for testing.
5) Reporting entities, as defined in Section 690.200(a)(1), are required to report any known or suspected common-source outbreaks and any intoxication caused by marine organisms, including paralytic shellfish poisoning, ciguatera and scombroid.
6) See Section 690.20(a)(9) and (a)(10) for guidance on the control of viral gastroenteritis outbreaks.
b) Control of Cases
1) Cases shall be evaluated to determine the need for isolation in a health care setting or at the person's residence. The isolation precautions followed shall be based on the most likely pathogen.
2) Persons who become ill due to an outbreak shall comply with restrictions specific to each etiologic agent addressed in this Part.
3) If the etiologic agent responsible for a foodborne or waterborne outbreak is not addressed in this Part and diarrhea or vomiting of infectious or unknown cause is present, food handlers and persons in sensitive occupations, including health care workers, who are ill shall not work until 48 hours after diarrhea or vomiting has resolved.
4) Persons with draining skin lesions shall not work as food handlers unless the drainage is contained by a dressing and lesions are not on the hands or forearms.
c) Control of Contacts
1) Contacts shall be evaluated to determine the need for quarantine.
2) Contacts to persons who become ill due to an outbreak shall comply with restrictions specific to each etiologic agent.
d) The local health authority shall implement appropriate control measures.
e) Sale of Food, Milk, etc. (See Section 690.30(b).)
f) Laboratory Reporting
1) Laboratories shall report to the local health authority clinical, animal, environmental or food specimens that have a positive result on a laboratory test indicative of and specific for detecting any outbreak of public health significance.
2) Laboratories shall submit to the Department's laboratory any positive food, environmental or animal samples resulting from an outbreak investigation.
