Summary

Trichinellosis outbreaks in humans have been linked to consuming horse meat. Detecting antibodies in horses is crucial for developing diagnostic tools and controlling parasite transmission through horse meat.

Area of Science:

  • Veterinary Parasitology
  • Foodborne Zoonoses
  • Molecular Epidemiology

Context:

  • Trichinellosis is a significant zoonotic disease transmitted through undercooked meat.
  • While pigs are a primary source, horse meat consumption has caused major outbreaks in Europe.
  • Previous identification of Trichinella species in infected humans and recent isolation from horses highlight the need for better diagnostics.

Purpose:

  • To review the transmission routes and diagnostic challenges of Trichinella in horses.
  • To emphasize the importance of developing sensitive and specific diagnostic assays for equine trichinellosis.
  • To facilitate the control of Trichinella transmission via horse meat for both animal and human consumption.

Summary:

  • Trichinellosis, a parasitic zoonosis, is primarily associated with consuming meat from pigs, bears, and foxes.
  • However, significant human outbreaks have been attributed to the ingestion of infected horse meat, with species like T. nativa, T. britovi, and T. spiralis identified.
  • Recent findings include the isolation of T. spiralis larvae from horses in Mexico and the detection of anti-Trichinella antibodies in horses globally using ELISA assays.
  • Experimental infections in horses have provided valuable data on antibody kinetics, aiding in diagnostic assay development.

Impact:

  • Improved diagnostic assays will enable accurate determination of Trichinella infection frequency in horses.
  • Effective control strategies for parasite transmission through horse meat can be designed.
  • Enhanced surveillance and control measures will reduce the risk of trichinellosis in humans consuming horse meat.
