  • The contaminated batch comprised 60,000 doses and has been ordered destroyed; Vetbiokhim previously recalled four additional batches and offered non-disclosure settlement agreements to affected owners.
  • Pseudorabies is typically fatal to dogs and attacks the central nervous system; no official death toll exists, though owners reported at least 300 deaths across several regions.
