Raccoon Health Assessment

HEALTH SURVEY OF FREE-RANGING RACCOONS (PROCYON LOTOR) IN CENTRAL PARK, NEW YORK, NEW YORK, USA: IMPLICATIONS FOR HUMAN AND DOMESTIC ANIMAL HEALTH

Key Takeaways:

  • Health assessments conducted on 113 free-ranging raccoons in Central Park, NY in conjunction with a trap-vaccinate-release program
  • Given the high raccoon, domestic animal, and human density in Central Park, there is potential for interspecies transmission of disease
  • These results indicate the presence of several significant pathogens for which raccoons may play an ecologic role, including Rabies virus, B. procyonisT. gondiiSalmonellaC. jejuni, and possibly parvoviruses

Summary of Findings:

  • Euthanized raccoons tested for rabies and canine distemper virus (CDV), respectively- all were negative for both
  • Endoparasitism was the most common necropsy finding, with identification of Baylisascaris procyonis in 75% necropsied raccoons
  • Median blood lead level was 7.3 ug/dL
  • Rabies virus neutralizing antibody titer was greater than or equal to 0.5 IU/mL in 10% unvaccinated and in 65% previously vaccinated raccoons
  • The majority were seropositive for canine parvovirus-2 (92%) and Toxoplasma gondii (65%).
  • Fewer were seropositive for Rickettsia rickettsii (10%).
  • None seropositive for CDV, canine adenovirus-1, or Borrelia burgdorferi.
  • Ectoparasites found during 16 of 118 (13.6%) included Ixodes texanus ticks (15/118, 12.7%) and Trichodectes octomaculatus lice (1/118, 0.8%).
  • Campylobacter jejuni detected in 6% fecal samples
  • Detected Salmonella enterica serotypes in 63.1% enteric cultures
