Sudden Death vs Found Dead: Guidelines on how to use these terms.

Sudden Death:

The animal was observed alive and in apparent good health but died unexpectedly within a short period.

There were no noticeable premonitory signs of illness or distress.

These cases often require urgent investigation due to the potential involvement of infectious diseases, toxins, or metabolic disturbances.

Possible causes include but are not limited to:

Clostridial diseases (e.g., blackleg, enterotoxemia)

Anthrax

Toxicity (e.g., lead, nitrates, cyanide poisoning)

Bloat or acute ruminal tympany

Metabolic disorders (e.g., hypocalcemia, hypomagnesemia)

Acute hemorrhages (e.g., ruptured aneurysm, trauma)

Found Dead:

The animal was discovered deceased, but the time and cause of death are unclear.

The animal might have shown signs of illness before death, but these were either unnoticed or not reported.

Investigation relies on post-mortem findings rather than clinical history.

Possible causes include but are not limited to:

Prolonged illness leading to unnoticed deterioration (e.g., pneumonia, parasitism, malnutrition)

Predation or injury-related death

Chronic conditions or neglected metabolic disorders

Environmental factors (e.g., extreme weather conditions)

Key Investigative Differences:

Sudden death cases often trigger urgent biosecurity concerns due to the potential for contagious or toxic causes.

Found dead cases may require a detailed history to determine if the death was due to natural aging, chronic illness, or environmental factors.

Fetus Submissions:

Monogastric fetuses or neonates under 10 days of age from a single dam (e.g., twins, litters) and small neonates (under 10 kilogram), such as suckling piglets from the same barn problem, will be handled as one submission and will be processed as a single necropsy fee. Note: if individual processing and reporting is required, the regular necropsy fee will apply per animal.

Up to 2 ruminant fetuses or neonates under 10 days of age from a single dam, will be handled as one submission and processed as a single necropsy fee. Additional fetuses from the same dam (e.g., triplets) will receive a second submission fee at a reduced rate.

Multiple Submissions from the same Flock or Herd:

Multiple birds from one poultry flock or barn (same problem, same ages), will be handled as one submission, Necropsy – Small Poultry Flock, and will be processed as a single necropsy fee.

Wherever possible, multiple samples from the same flock or herd will be combined by the PDS lab to minimize costs for certain tests. When submitting multiple samples from the same flock or herd, submit all fresh tissues in individual containers and clearly identify the source of each sample. 

If more than 10 Histopathology slides are required per submission, the appropriate Histopathology-Paraffin process, embed, cut, and stain H&E fee will apply for each slide.

Abortion Submissions:

For Abortion submissions refer to Maximising the Chance of Achieving Diagnoses on Bovine Abortions and a Diagnostic Algorithm Based on Western Canadian Bovine Diseases is available at the top of this page.

Swine Submissions:

Guidelines for Swine Multi Animal Submissions is available at the top of this page. 

Complex Necropsies: Additional charges may apply for cases that are more complex than a routine necropsy (e.g., neurological/spinal, research interest cases, etc.).

Note: the first 10 Histopathology slides, if required, are included in the cost of the necropsy. If more than 10 Histopathology slides are required per submission, the appropriate Histopathology-Paraffin process, embed, cut, and stain H&E fee will apply for each slide

Sample preparation fee will apply for submissions to the Microbiology Laboratory that are too large to process in the Microbiology Laboratory. The fees are as follows:

Sample that requires trim down for processing in the Microbiology lab (e.g., liver or placenta section submitted to Micro that is too large to process in that lab) - $50.00.
Sample that requires tissue collection for Microbiology testing that requires consultation with the pathologist such as collecting samples from a whole piglet or taking a joint swab from a leg - $80.00.

Microbiology and Clinical Pathology testing on Necropsy Cases:

Microbiology and Clinical Pathlolgy testing is not included in the necropsy fees, but additional testing is considered necessary in over 50% of necropsy cases. Pathologists often send samples for culture, etc. on a routine basis to confirm or rule out bacterial infections. If no additional testing is to be performed, please specify this on the animal history form at the time of submission.

Sample Hold Requests:

A $20.00 hold fee will apply to requests for PDS to hold and maintain tissue samples for further/future testing. This hold fee does not apply to regular necropsy submissions. The hold fee is non-refundable. 

Contact the Diagnostic Services Office at (306) 966-7316 or visit the PDS website (pdsinc.ca) for information on local cremation services offered through Family Pet Cremation Services. Clients will be assessed additional fees for provision of this service. This service is limited to small animal cases whose Risk Assessment has eliminated the possibility of Risk Group 3 organism(s).

Rabies Confirmatory Testing is now performed only when a collaborative and consultative decision between Public Health and the SK Ministry of Environment’s Rabies Risk Assessment Veterinarian (RRAV) have determined the “risk to either animal or human health” warrants that a brain sample should be collected and transported to the Rabies Laboratory in Lethbridge Alberta. PDS serves as a Collection Depot for sample drop off. Testing and transportation fees are covered by SK Ministry of Agriculture when Program criteria are met. Consult RRAV for further explanation 1-844-7-RABIES (1-844-772-2437).

All whole-body bovine, ovine and bison submissions presented for necropsy examination must have a valid Canadian Cattle Identification Agency (CCIA) RFID ear tag assigned and affixed prior to submission to the PDS Necropsy Facility and/or upon leaving their herd of origin. This includes very late term fetuses and neonates. The PDS Necropsy Facility is mandated to document and “Retire” the assigned CCIA tag in compliance with the Health of Animals Act and as mandated by the CCIA Program and the Canadian Food Inspection Agency (CFIA).
