Committee reviews St. Louis County shelter response after parvovirus outbreak; veterinarian says 19 animals were euthanized

St. Louis County Council’s Committee of the Whole continued an investigation Thursday into shelter operations and a parvovirus outbreak after the county took over animal care and control from the Animal Protective Association earlier this year. Dr. Douglas Pernicoff, the county’s veterinary director under subpoena, testified about the outbreak, staffing shortfalls, procurement problems and the shelter’s protocols.

Pernicoff said the first clinically positive parvovirus case appeared in mid- to late April and that the shelter “euthanized” an initial dog because there was no place to isolate or provide intensive treatment. He told the committee that supervisors subsequently identified a list of animals for euthanasia and that, over a short period, staff carried out roughly 19 euthanasias to try to stop spread in a population he estimated at about 240 animals.

Why it matters: County officials are examining whether the shelter had adequate procedures, staffing and supplies after the transfer from the APA and whether communications between on-site staff and Department of Public Health leadership were sufficient during the outbreak.

Pernicoff described the medical constraints that guided his team’s choices. He told the committee that an intensive treatment regimen for parvovirus — intravenous fluids, anti-nausea medication, broad supportive care and, in some cases, monoclonal antibody therapy — was effectively unavailable at scale because the shelter lacked sufficient IV supplies, staffing and budget. He said a monoclonal-antibody treatment would have cost roughly $1,100–$1,200 per large dog and would have been impractical to apply to the dozens of sick animals he says were exposed.

He acknowledged a communication lapse with senior health officials, saying, “I was remiss in not calling her that we were gonna euthanize animals, but I’m sure she was aware of what was going on.” Pernicoff told the panel he had circulated a proposed euthanasia decision tree to supervisors earlier in the year but that it was not formally adopted or signed by senior leadership.

Council members asked detailed questions about intake procedures, vaccination and recordkeeping. Pernicoff said intake vaccinations were supposed to be administered by animal control officers (ACOs) but that staffing shortages and high intake volumes meant some animals did not receive appropriate intake vaccines; he described at least one positive dog that had no intake vaccine recorded. He said the shelter’s electronic case-management system (referred to in testimony as “Chameleon”) contained intake and euthanasia records and that the committee’s subpoenaed production included many files — a document dump the council later described as roughly 28,000 pages.

Pernicoff also described operational differences after the APA departure: fewer kennel-cleaning staff (APA averaged an estimated 15–17 cleaners per day; county staffing was lower), delays in procurement, and late delivery of the county’s standard operating procedures (he said the final SOPs did not arrive until early May). He said these limitations constrained quarantine, isolation and treatment options.

Other witnesses and public commenters pressed the council on funding and policy. Shannon Blatzky, who said she holds a Master of Science in shelter medicine, urged the council to pass Bill 41 to permit fee-waived adoptions and Bill 116 to allow the shelter broader authority to accept grants and donations. A resident speaker asked the council to publish a detailed budget plan for any requested shelter funding.

Council action and records requests: Committee members directed staff to collect and review electronic records, and multiple members asked legal counsel to obtain targeted Chameleon reports (e.g., intake-to-disposition timelines for animals euthanized during the outbreak). The committee also took official notice of St. Louis County ordinances and resolutions related to shelter operations; multiple council members said they expected additional hearings and follow-up testimony.

Pernicoff said he resigned once in February, was invited back, and then left again after the early May outbreak and an exchange with county leadership; he said he later provided a resignation letter that was accepted. He characterized the shelter’s core problems as funding, staffing and insufficient space for isolation and quarantine. He repeatedly credited the on-site licensed veterinary technician, Nikki Bennett, and other on-site staff for work to control the outbreak.

Ending: Council members said they would reconvene follow-up sessions, review the subpoenaed files and request specific Chameleon extracts to trace the intake, treatment and disposition of animals involved in the outbreak. Public commenters asked the council to prioritize spay/neuter funding and to consider operational changes such as expanded adoption policy tools and greater procurement flexibility.

(Reporting note: The committee recorded testimony and entered documents into the record; committee staff said more hearings are likely.)
