SAMPLING PROCEDURES 4.1. Precautions to be taken Contamination and deterioration of samples must be prevented because they may affect the analytical results. Each lot to be checked must be sampled separately. 4.2. Collection of primary samples The minimum number of primary samples to be taken from a lot from Table 1, or Table 2 in the case of a suspect lot of meat or poultry. sample should be taken from a randomly chosen position in the practicable. The primary samples must consist of sufficient material laboratory sample(s) required from the lot. † ‡ § Note: Sampling devices required for grain , pulses and tea are described ** recommendations and those required for dairy products are described Table 1

Notes: (a) The table assumes random sampling.

(b) Where the number of primary samples indicated in Table than about 10% of the units in the total lot, the number samples taken may be fewer and should be calculated n = n /((1+(n -1))/N) o o where n = minimum number of primary samples to be n = number of primary samples given in Table 2 o N = number of units, capable of yielding a primary lot.

(c) Where a single primary sample is taken, the probability a non-compliance is similar to the incidence of non-compliant residues.

(d) For exact or alternative probabilities, or for a different non-compliance, the number of samples to be calculated from: n 1 - p = (1 - i) Where p is the probability and i is the incidence of residues in the lot (both expressed as fractions, not and n is the number of samples. 4.3. Preparation of the bulk sample The procedures for meat and poultry are described in Table 3. sample is considered to be a separate bulk sample. The procedures for plant products, eggs or dairy products are described and 5. The primary samples should be combined and mixed well, if form the bulk sample. S.L.430.04 AND ON PRODUCTS OF PLANT AND ANIMAL ORIGIN

mixing to form the bulk sample is inappropriate or impractical, the alternative procedure may be followed. Where units may be damaged (and may be affected) by the processes of mixing or subdivision of the bulk where large units cannot be mixed to produce a more uniform residue units should be allocated randomly to replicate laboratory samples taking the primary samples. In this case, the result to be used should be valid results obtained from the laboratory samples analysed. Table 3
