Special Notes
Peanuts, shelled (includes peanut ingredients) 25 480g FS402D FS403D

Mycotoxins such as aflatoxin may occur in pockets within the product; therefore several sub-samples need to be selected from throughout the lot to create a composite sample that accurately represents the entire lot.

Use paper or cloth sample bags or clean cardboard boxes to collect and store samples. Moisture formation in plastic bags can occur, which may cause mould growth and affect the integrity of the sample.

For follow-up samples to unsatisfactory FS428D/FS429D results, choose the appropriate sample plan code from the following:

  • FS420F: Domestic: Vomitoxin (Deoxynivalenol – DON) in Wheat and Wheat-based Products
  • FS421F: Imported: Vomitoxin (Deoxynivalenol - DON) in Wheat and Wheat-based Products
  • FS422F: Domestic: Ochratoxin A (OTA) in food
  • FS423F: Imported: Ochratoxin A (OTA) in imported food
Pasteurized juice, juice blends and cider 5 100 mL FS430D FS431D

When sampling a juice blend, ensure the product is not 'syrupy' or 'pulpy'.

Juice may be coloured.

Juices or ciders intended for fermentation into alcohol or vinegar should not be sampled.

Unpasteurized juice, juice blends and cider 5 100 mL FS432D FS433D

When sampling a juice blend, ensure the product is not 'syrupy' or 'pulpy'.

Special Notes
Foods that are regulated

5 100g Chemical contaminants FS400D FS401D

Do not duplicate testing of the same product for other sampling plans.

These codes are only to be used for complaints related to IMFP products, not relating to scoping and/or recall investigations, but may be used for trade complaints.

Consult the appropriate Area Network Specialist for guidance on appropriate analysis, sampling number and size. Select the specific analysis requested under 'Analysis Types' in LSTS.

If packages are < 100g each, the # of sub-samples should be increased in order to provide the minimum 500 g sample quantity for analysis.

If the sub-sample size is large (i.e. > 250 g or 500 g), employ a bulk sampling strategy (i.e. sample 100g from each package to make one sub-sample).

If it might compromise the analysis of the sample to take portions, sample 5 whole/unopened products/packages. For samples related to consumer illness complaints:

  • Include the complainant's opened sample, and any available unopened samples (up to 5 or 500g).
  • If possible, also include a similar product from a different manufacturer (domestic products only) as a reference.
  • Contact the lab if you have questions regarding selecting a reference product.
  • Send all samples in the same shipment.
  • Provide the courier tracking number to the lab by e-mail, with the IMS number in the subject line.

Do not duplicate testing of the same product for other sampling plans.

These codes are only to be used for IMFP products not relating to scoping and/or recall investigations, complaints, trade complaints, nor for which another sampling plan exists.

Consult the appropriate Area Program Specialist for guidance on appropriate analysis, sampling number and size. Select the specific analysis requested under 'Analysis Types' in LSTS.

If packages are < 100g each, the # of sub-samples should be increased in order to provide the minimum 500 g sample quantity for analysis.

If the sub-sample size is large (i.e. > 250 g or 500 g), employ a bulk sampling strategy (i.e. sample 100g from each package to make one sub-sample).

If it might compromise the analysis of the sample to take portions, sample 5 whole/unopened products/packages.

A reference sample of a similar product (different brand or manufacturer) may be required to validate a new matrix. Contact the lab to determine if this is required.

Table Note

Table Note 47

The FDR states that 15 ppb is the maximum allowable level for aflatoxin in nuts or nut products. Please note: the standard error in the testing methodology causes a 50% variance in the reported result. Consequently, action should only be taken if aflatoxin result is reported in nuts at levels above 23 ppb.
