GOST 31468-2012 PDF

Full title and description

ГОСТ 31468-2012 — Мясо птицы, субпродукты и полуфабрикаты из мяса птицы. Метод выявления сальмонелл. (English title: Poultry meat, edible offal and poultry meat ready-to-cook. Method for detection of Salmonellae).

Abstract

This interstate (GOST) standard specifies a microbiological method for the detection (isolation and preliminary identification) of bacteria of the genus Salmonella in poultry meat, edible offal and ready-to-cook poultry products. The document covers sampling, non-selective and selective enrichment, plating on differential/ selective media, selection of suspect colonies and their biochemical/serological identification as part of routine microbiological control of poultry products.

General information

• Status: Active / in force.
• Publication date: Approved 14 November 2012 (designation year 2012); introduced into effect 1 July 2013.
• Publisher: Federal Agency on Technical Regulating and Metrology (Rosstandart) as an interstate (GOST) standard; developed with participation of VNIIPP and industry stakeholders.
• ICS / categories: 67.120.20 (Poultry and eggs / food products — food microbiology related to poultry).
• Edition / version: GOST 31468-2012 (first issue; introduced for use July 1, 2013).
• Number of pages: 12 pages.

Scope

The standard applies to raw poultry meat, edible offal and ready-to-cook poultry meat products and establishes a cultural/microbiological procedure for detection of Salmonella spp. It is intended for use in laboratory testing for regulatory surveillance, quality control and conformance assessments of poultry products. The procedure covers sample preparation, enrichment stages, selective media and criteria for presumptive colony selection and further biochemical/serological confirmation.

Key topics and requirements

• Sampling requirements and sample sizes for poultry meat, offal and ready-to-cook products.
• Non-selective pre-enrichment and selective enrichment steps to recover stressed Salmonella cells.
• Use of differential and selective agar media (e.g., XLD, Endo, bismuth sulfite, Ploskirev) for isolation of suspect colonies.
• Colony morphology criteria, selection of suspect colonies and procedures for subculture.
• Biochemical identification and serological reactions for confirmation of Salmonella genus/species.
• Reporting of results and interpretation for microbiological control purposes.

Typical use and users

Laboratories performing food microbiology testing (public health, regulatory and commercial QC labs), poultry processors’ quality departments, certification bodies and veterinary/food safety authorities use this standard for routine detection of Salmonella in poultry products and for conformity assessment to national/interstate sanitary requirements.

Related standards

GOST 31468-2012 is used alongside other national and international methods for Salmonella detection and food microbiology (for example, the ISO horizontal methods for Salmonella such as ISO 6579 series). It also serves as part of the normative base referenced by technical regulations applicable to food safety and poultry products in the EAEU.
