  2. 2. (1) Immediately place the implicated portion(s) of theharvest area(s) in the closed status;(2) Notify receiving states and the FDA RegionalShellfish Specialist that a potential health risk isassociated with shellfish harvested from theimplicated growing area
  3. 3.  Upon closing an implicated area for problems otherthan natural occurring pathogens and/or Biotoxins,the Authority shall review the growing areaclassification and determine if a growing areaclassification problem exists. The review shallinclude at a minimum:1. A review of the growing area classification file records;2. A field review of existing pollution sources;3. A review of actual and potential intermittent pollutionsources, such as vessel waste discharge and wastewaterdischarge from treatment plant collection systems; and4. Examination of water quality subsequent to the illnessoutbreak.
  4. 4.  Upon closing an implicated portion(s) of theharvest area(s) for naturally occurring pathogensand/or Biotoxins, the Authority:1. Shall follow an existing marine Biotoxincontingency plan, if appropriate.2. Shall collect and analyze samples relevant to theinvestigation, if appropriate.3. Shall keep the area closed until it has beendetermined that levels of naturally occurringpathogens and/or Biotoxins are not a publichealth concern.4. May limit the closure to specific shellfishspecies when FDA concurs that the threat ofillness is species specific.
  5. 5.  When the growing area is determined the problem, theAuthority shall:1. Place the growing area in the closed status until:a) The Authority verifies that the area is properly classified, usingcurrent data, in compliance with the NSSP Model Ordinance; orb) Shellfish from the growing area are confirmed as the cause ofillness but it has been determined that the event which caused thecontamination no longer exists;2. Keep the area closed for a minimum of 21 days ifthe illness is consistent with viral etiology; and3. Develop a written report summarizing the findingsof the investigation and actions taken.
  6. 6.  The Authority shall review the following factors:a) The documentation to trace the shellfish to itssource;b) The classification assigned to the growing areaand whether the sanitary survey datasupporting that classification is current; andc) The probability of illegal harvesting from areasclassified as restricted or prohibited, or in theclosed status.
  7. 7.  The Authority shall take no further action when theAuthority determines that:a) The growing area is properly classified;b) No illegal harvesting is taking place; andc) There is no reason to believe that the growingarea is the source of the pathogens.
  8. 8.  When the Authority determines that the growingarea is not properly classified, the Authority shalltake immediate action to:a) Change the existing classification to the correctclassification; orb) Close the growing area until the correctclassification can be determined
  9. 9.  When a growing area continues to demonstrate thepresence of human pathogen isolates or othertoxins in shellfish meats in the absence of illness,the Authority shall perform a risk assessment todetermine the correct classification for an area
