No raw materials or ingredients shall be accepted by a food business if they are known to be, or might reasonably be expected to be, so contaminated with parasites, pathogenic micro-organisms or toxic, decomposed or foreign substances that, after normal sorting and/or preparatory or processing procedures hygienically applied by food businesses, they would still be unfit for human consumption.
'Contaminant' means any substance not intentionally added to food which is present in such food as a result of the production (including operations carried out in crop husbandry, animal husbandry and veterinary medicine), manufacture, processing, preparation, treatment, packing, packaging, transport or holding of such food, or as a result of environmental contamination. Extraneous matter, such as, for example, insect fragments, animal hair, etc, is not covered by this definition.
Extraneous matter: all matter in a sample of cereals retained by a sieve with apertures of 3.5 millimetres (with the exception of grains of other cereals and particularly large grains of the basic cereal) and that passing through a sieve with apertures of 1 millimetre shall be considered as extraneous matter. Also included in this group are stones, sand, fragments of straw and other impurities in the samples which pass through a sieve with apertures of 3.5 millimetres and are retained by a sieve with apertures of 1 millimetre. This definition does not apply to maize. For that cereal, all matter in a sample which passes through a sieve with apertures of 1 millimetre, as well as all the impurities mentioned in the preceding subparagraph, must be considered as extraneous matter.
