Overview
- Resolution 1341/2025, published in the Boletín Oficial, establishes a unified framework for collecting and comparing human odor traces using trained dogs and specialized operators.
- Federal forces — Policía Federal, Gendarmería, Prefectura, PSA and the Federal Penitentiary Service — must update internal rules, and provinces and Buenos Aires City are invited to adhere via the Consejo de Seguridad Interior.
- The protocol defines three collection modalities — direct, indirect and instrumental — and references devices such as the Human Odor Transfer Unit.
- Samples must be sealed in sterilized glass containers and sent, with judicial authorization, to a centralized odor bank kept at 15–20°C and 60–70% relative humidity to preserve trace integrity.
- The standard sets usefulness limits of up to three years for direct samples and two years for indirect or instrumental ones, and the ministry says implementation requires no additional state spending.
