ALINORM 10/33/4150APPENDIX VAlmonds – shelled nutsHazelnuts – shelled nutsPistachios – inshell nuts (equivalent to about 5 kg shelled nuts per test sample that is calculated on the basis ofthe actual edible portion in the sample)Brazil nuts – shelled nutsSample preparation – sample shall be finely ground and mixed thoroughly using a process, e.g., dry grind with avertical cutter mixer type mill, that has been demonstrated to provide the lowest sample preparation variance.Preferably, Brazil nuts should be ground as slurry.Analytical method – performance based (see Table 2)Decision rule – If the aflatoxin test result is less than or equal to 10 µg/kg total aflatoxin in both test samples, thenaccept the lot. Otherwise, reject the lot.The operating characteristic curve describing the performance of the sampling plan for the four ready-to-eattreenuts is shown in Annex II.11. To assist member countries implement these two Codex sampling plans, sample selection methods, samplepreparation methods, and analytical methods required to quantify aflatoxin in laboratory samples taken from bulktreenut lots are described in the following sections.SAMPLE SELECTIONMaterial to be sampled12. Each lot, which is to be examined for aflatoxin, must be sampled separately. Lots larger than 25 tonnes should besubdivided into sublots to be sampled separately. If a lot is greater than 25 tonnes, the number of sublots is equal tothe lot weight in tonnes divided by 25 tonnes. It is recommended that a lot or a sublot should not exceed 25 tonnes.The minimum lot weight should be 500 kg.13. Taking into account that the weight of the lot is not always an exact multiple of 25 tonne sublots, the weight of thesublot may exceed the mentioned weight by a maximum of 25%.14. Samples should be taken from the same lot, i.e. they should have the same batch code or at the very least the samebest before date. Any changes which would affect the mycotoxin content, the analytical determination or make theaggregate samples collected unrepresentative should be avoided. For example do not open packaging in adverseweather conditions or expose samples to excessive moisture or sunlight. Avoid cross-contamination from otherpotentially contaminated consignments nearby.15. In most cases any truck or container will have to be unloaded to allow representative sampling to be carried out.Incremental Sample Selection16. Procedures used to take incremental samples from a treenut lot are extremely important. Every individual nut in thelot should have an equal chance of being chosen. Biases will be introduced by sample selection methods ifequipment and procedures used to select the incremental samples prohibit or reduce the chances of any item in thelot from being chosen.17. Since there is no way to know if the contaminated treenut kernels are uniformly dispersed throughout the lot, it isessential that the aggregate sample be the accumulation of many small incremental samples of product selectedfrom different locations throughout the lot. If the aggregate sample is larger than desired, it should be blended andsubdivided until the desired laboratory sample size is achieved.Number of Incremental Samples for Lots of varying weight18. The number and size of the laboratory sample(s) will not vary with lot (sublot) size. However, the number and sizeof the incremental samples will vary with lot (sublot) size.19. The number of incremental samples to be taken from a lot (sublot) depends on the weight of the lot. Table 1 shallbe used to determine the number of incremental samples to be taken from lots or sublots of various sizes below 25tonnes. The number of incremental samples varies from a minimum of 10 and to a maximum of 100.
