# The Feeding Stuffs (Sampling and Analysis) Regulations 1999, TEXT REFERRED TO IN PARAGRAPH 9(b)


(1) For packaged feeding stuffs, a part of the contents of the packages to be sampled shall be removed, using a spear or shovel, after having, if necessary, emptied the packaged separately.
(2) Any lumps shall be broken up (if necessary by separating them out and returning them to the sample) in each aggregate sample separately.
6.2.
Incremental samples
6.2.A.
In relation to the control of substances or products uniformly distributed throughout the feedingstuff
Incremental samples must be taken at random throughout the whole sampled portion and they must be of approximately equal sizes.
6.2.A.1.
Loose feedingstuffs
A notional division shall be made of the sampled portion into a number of approximately equal parts. A number of parts corresponding to the number of incremental samples required in accordance with 5.A.2. shall be selected at random and at least one sample taken from each of these parts.
Where appropriate, sampling may be carried out when the sampled portion is being moved (loading or unloading).
6.2.A.2.
Packaged feedingstuffs
Having selected the required number of packages for sampling as indicated in 5.A.2, part of the contents of each package shall be removed using a spear or shovel. Where necessary, the samples shall be taken after emptying the packages separately.
6.2.A.3.
Homogeneous or homogenizable liquid or semi-liquid feedingstuffs
Having selected the required number of containers for sampling as indicated in 5.A.2, the contents shall be homogenized if necessary and an amount taken from each container.
The incremental samples may be taken when the contents are being discharged.
6.2.A.4.
Non-homogenizable, liquid or semi-liquid feedingstuffs
Having selected the required number of containers for sampling as indicated in 5.A.2, samples shall be taken from different levels.
Samples may also be taken when the contents are being discharged by the first fractions should be discarded:
In either case the total volume taken must not be less than 10 litres.
6.2.A.5.
Feed blocks and mineral licks
Having selected the required number of blocks or licks for sampling as indicated in 5.A.2, as part of each block or lick shall be taken.
6.2.B.
In relation to the control of undesirable substances or products likely to be distributed non-uniformly throughout the feedingstuff, such as aflatoxins, rye ergot, castor-oil plant and crotalaria in straight feedingstuffs.
A notional division shall be made of the sampled portion into a number or approximately equal parts, corresponding to the number of aggregate samples provided for in 5.B.3. If this number is greater than one, the total number of incremental samples provided for in 5.B.2. shall be distributed approximately equally over the different parts. Then samples of approximately equal sizes, and such that the total amount in the samples from each part is not less than the minimum 4kg quantity required for each aggregate sample, shall be taken. Incremental samples taken from different parts shall not be aggregated.
6.3.
Preparation of aggregate samples
6.3.A.
In relation to the control of substances of products distributed uniformly throughout the feedingstuff
The incremental samples shall be mixed to form a single aggregate sample.
6.3.B.
In relation to the control of undesirable substances or products likely to be distributed non-uniformly throughout the feedingstuff, such as aflatoxins, rye ergot, castor-oil plant and crotalaria in straight feedingstuffs
The incremental samples from each part of the sampled portion shall be mixed and the number of aggregate sampled provided for in 5.B.3, made up taking care to note the origin of each aggregate sample.
6.4.
Preparation of final samples
The material in each aggregate sample shall be carefully mixed to obtain an homogenized sample. If necessary the aggregate sample should first be reduced to at least 2kg or two litres (reduced sample) either by using a mechanical divider or by the quartering method.
At least three final samples shall then be prepared, of approximately the same amount and conforming to the quantitative requires of 5.A.4 or 5.B.4. Each sample shall be put into an appropriate container. All necessary precautions shall be taken to avoid any change of composition of the sample, contamination or adulteration which might arise during transportation or storage.
