(1) in point B.1.7 "Packaging and transmission of samples", the following second paragraph is added: "In case of sampling for PAH analysis plastic containers shall be avoided if possible as they could alter the PAH content of the sample. Inert, PAH-free glass containers, adequately protecting the sample from light, shall be used wherever possible. Where this is practically impossible, at least direct contact of the sample with plastics shall be avoided, e.g. in case of solid samples by wrapping the sample in aluminium foil before placing it in the sampling container."; (2) points B.2 and B.3 are replaced by the following: "B.2. SAMPLING PLANS B.2.1. Division of lots into sublots Large lots shall be divided into sublots on condition that the sublot may be separated physically. For products traded in bulk consignments (e.g. cereals) Table 1 shall apply. For other products Table 2 shall apply. Taking into account that the weight of the lot is not always an exact multiple of the weight of the sublots, the weight of the sublot may exceed the mentioned weight by a maximum of 20 %. B.2.2. Number of incremental samples The aggregate sample shall be at least 1 kg or 1 litre except where it is not possible, e.g. when the sample consists of 1 package or unit. The minimum number of incremental samples to be taken from the lot or sublot shall be as given in Table 3. In the case of bulk liquid products the lot or sublot shall be thoroughly mixed in so far as possible and in so far it does not affect the quality of the product, by either manual or mechanical means immediately prior to sampling. In this case, a homogeneous distribution of contaminants is assumed within a given lot or sublot. It is therefore sufficient to take three incremental samples from a lot or sublot to form the aggregate sample. The incremental samples shall be of similar weight/volume. The weight/volume of an incremental sample shall be at least 100 grams or 100 millilitres, resulting in an aggregate sample of at least about 1 kg or 1 litre. Departure from this method shall be recorded in the record provided for under point B.1.8 of this Annex. Table 1 Subdivision of lots into sublots for products traded in bulk consignments Lot weight (ton) Weight or number of sublots ≥ 1500 500 tonnes > 300 and < 1500 3 sublots ≥ 100 and ≤ 300 100 tonnes < 100 — Table 2 Subdivision of lots into sublots for other products Lot weight (ton) Weight or number of sublots ≥ 15 15-30 tonnes < 15 — Table 3 Minimum number of incremental samples to be taken from the lot or sublot Weight or volume of lot/sublot (in kg or litre) Minimum number of incremental samples to be taken < 50 3 ≥ 50 and ≤ 500 5 > 500 10 If the lot or sublot consists of individual packages or units, then the number of packages or units which shall be taken to form the aggregate sample is given in Table 4. Table 4 Number of packages or units (incremental samples) which shall be taken to form the aggregate sample if the lot or sublot consists of individual packages or units Number of packages or units in the lot/sublot Number of packages or units to be taken ≤ 25 at least 1 package or unit 26-100 about 5 %, at least 2 packages or units > 100 about 5 %, at maximum 10 packages or units The maximum levels for inorganic tin apply to the contents of each can, but for practical reasons it is necessary to use an aggregate sampling approach. If the result of the test for an aggregate sample of cans is less than but close to the maximum level of inorganic tin and if it is suspected that individual cans might exceed the maximum level, then it might be necessary to conduct further investigations. Where it is not possible to carry out the method of sampling set out in this chapter because of the unacceptable commercial consequences (e.g. because of packaging forms, damage to the lot, etc.) or where it is practically impossible to apply the abovementioned method of sampling, an alternative method of sampling may be applied provided that it is sufficiently representative for the sampled lot or sublot and is fully documented. B.2.3. Specific provisions for the sampling of large fish arriving in large lots In case the lot or sublot to be sampled contains large fishes (individual fishes weighing more than about 1 kg) and the lot or sublot weighs more than 500 kg, the incremental sample shall consist of the middle part of the fish. Each incremental sample shall weigh at least 100 g. B.3. SAMPLING AT RETAIL STAGE Sampling of foodstuffs at retail stage shall be done where possible in accordance with the sampling provisions set out in point B.2.2 of this Annex. Where it is not possible to carry out the method of sampling set out in point B.2.2 because of the unacceptable commercial consequences (e.g. because of packaging forms, damage to the lot, etc.) or where it is practically impossible to apply the abovementioned method of sampling, an alternative method of sampling may be applied provided that it is sufficiently representative for the sampled lot or sublot and is fully documented."; (3) in the first paragraph of point C.1 "Laboratory Quality Standards", footnote 1 is deleted; (4) in point C.2.2.1 "Specific procedures for lead, cadmium, mercury and inorganic tin", the second paragraph is replaced by the following: "There are many satisfactory specific sample preparation procedures which may be used for the products under consideration.

Specific procedures for polycyclic aromatic hydrocarbons The analyst shall ensure that samples do not become contaminated during sample preparation. Containers shall be rinsed with high purity acetone or hexane before use to minimise the risk of contamination.
