1. Application

This method is applicable to the sampling and examination of mechanically separated meat for magnetic metal particles and heavy filth to determine compliance with Sections 4, 5 and 7 of the Food and Drugs Act. This method replaces ExFLB No. 11.

2. Definition of Terms

A lot is defined as that amount (volume, weight, etc.) of the food which is produced, stored and/or shipped under conditions as nearly uniform as possible, preferably designated by a common container code or marking, and, in any event, consisting of not more than one variety, grade or type of product from a single identifiable source.

3. Collection of Samples

3.1 Obtain three sample units of at least 225 g each, selected at random from the lot using appropriate sampling equipment and containers. Three sample units constitute a sample.

3.2 Each sample unit must be kept separate and labelled 1, 2 and 3. Complete information respecting the lot size, weight of individual containers, country of origin, exporter, importer, or domestic manufacturer, and product and lot identification should be recorded and should accompany the sample.

4. Materials and Special Equipment

1) Balance

2) Stirrer hot plate

3) Smooth spin bar magnets, teflon coated (1 x 5 cm recommended)

4) Non-magnetic tweezers

5) Glass beakers (400 mL, 2 L)

6) Rubber policeman attached to a glass or plastic stirring rod
