Escopo e aplicabilidade

This standard applies specifically to irradiated hog carcasses (pork) contaminated with Trichinella, where the parasitic density does not exceed 5 larvae per 24 meat slide specimens. It is designed for pork treated with gamma rays or electron beams to ensure the inactivation of the Trichinella parasite. It does not apply to pork products intended for general irradiation preservation without the specific risk of Trichinella contamination.

Requisitos técnicos

The standard specifies a strict overall average absorbed dose of 0.65 kGy for the irradiation process, utilizing radiation sources such as 60Co, 137Cs gamma rays, or electron beams generated at energies below 10 MeV. The irradiation principle mandates that the process is uniform, with reliable and accurate dose delivery. The core parasitological requirement dictates that the Trichinella in the pork must be completely inactivated and unable to develop into adult parasites within the intestinal tract of animals. Furthermore, sensory indicators and physicochemical parameters must strictly comply with the referenced national standard GB 2722 for fresh pork hygiene.

Métodos de ensaio

Compliance verification involves a specialized bioassay testing method detailed in the standard's supplement. The procedure requires the artificial collection of muscle Trichinella using a 1% pepsin digestion solution, followed by an inoculation test in laboratory mice. Researchers examine the mice's intestines microscopically to confirm the absence of adult intestinal Trichinella, thereby verifying successful inactivation.

Perguntas frequentes

What products are regulated under GB 14891.6-94?

It applies to pork carcasses specifically contaminated with Trichinella (with a parasitic density of no more than 5 larvae per 24 meat slide specimens) that have been treated with gamma rays or electron beams.

How does GB 14891.6-94 verify the inactivation of Trichinella?

The standard mandates that irradiated pork must undergo a strict bioassay to confirm that the Trichinella larvae are completely inactivated and cannot develop into adult intestinal parasites in host animals.

Are there any specific sensory or physicochemical limits defined in this standard?

It references GB 2722 for sensory indicators and physicochemical requirements, meaning the irradiated product must still meet the baseline hygiene standards for fresh pork.
