SARS-CoV-2 infection has been sporadically reported in animals with resolution of clinical signs in symptomatic animals. Few animals have died under natural exposures and for those animals that have died, there were significant pre-existing  conditions.  There has been a concerted effort to standardize and collect data on diagnostic testing on a national level.  The attached supplemental necropsy sample inventory checklist was developed to provide a standardized data collection for any necropsies of  SARS-CoV-2 suspect or confirmed animals.

The supplemental checklist is intended to gather information on samples collected for histopathology and/or archiving.  The two page checklist is not intended to replace any in-house documents, nor does it provide guidance on how to conduct a necropsy. Information on specific samples for SARS-CoV-2 testing is provided.

The completed checklist can be returned via email to:  [email protected]. 

Additional Information

• For any animal testing non-negative for SARS-CoV-2, contact USDA-NVSL to discuss necessary next steps and confirmatory testing:  [email protected] or (515)337-7551 (during business hours)
• This sample inventory list is designed to assist prosectors who may not routinely perform necropsies and/or provide guidance to individuals who may perform a necropsy on a SARS-CoV-2 positive (or suspected positive) animal. 
• The sample inventory list is not intended to replace necropsy forms, sample submission forms, or any other internal forms utilized in clinical, diagnostic laboratory, or research facilities. This list is a supplemental form to aid in assessment of collected samples for tracking purposes. 
• The sample inventory list is comprehensive and can be utilized for limited sample and tissue collection (i.e. cosmetic necropsies) or during complete necropsies where more robust tissue collection occurs.
• A complete necropsy and collection of a full set of samples and tissues is optimal but not always feasible.  If a complete postmortem examination cannot be performed, sample collection should be focused on the respiratory and digestive systems. 
• The document can be printed.  Mark the appropriate check boxes including samples not collected.
