Summary

1. Test Materials for the 1st round of the 2017 GAFTA Analysts Scheme were dispatched in March 2017. Three test materials were distributed.

Feed Grain Mycotoxin Sample ID : 2017:F1 2017:G1 2017:M1 Sample type : Palm Kernel Meal Barley Wheat Sample state : Milled Un-milled Milled Number distributed : 236 282 73 Data returned : 219 270 39 % returned 92.8 95.8 53.4

2. A total of 292 participants in 54 countries received one or more of the test materials depending on

the requirements of their analytical laboratory. Results were returned from 279 participants. The countries involved were as follows :

Argentina 14 Mexico 1 Australia 5 Moldova 1 Belgium 1 The Netherlands 6 Brazil 17 Nicaragua 1 Bulgaria 6 Norway 1 Canada 4 Pakistan 1 China 4 Paraguay 2 Croatia 2 Peru 3 Denmark 2 Poland 6 Egypt 2 Romania 10 Estonia 2 Russia 46 Finland 1 Serbia 2 France 8 Singapore 1 Germany 9 Slovakia 1 Greece 1 Spain 9 Hungary 11 Sweden 1 Iceland 1 Tanzania 2 India 18 Thailand 5 Indonesia 1 Turkey 10 Iran 1 Uganda 1 Israel 1 Ukraine 22 Italy 8 United Arab Emirates 3 Kazakhstan 3 United Kingdom 4 Kenya 2 United States of America 11 Latvia 6 Uruguay 3 Lithuania 4 Vietnam 3 Malaysia 1

3. For analyses other than moisture, the moisture basis on which the results are expressed was also

requested. In order to compare directly all results reported on a “dry matter” basis have been converted to be expressed on an “as received” basis. The participants own moisture results have been used to perform this calculation. Where the participants have not stated whether the results are on an “as received” or “dry matter” basis, it has not been possible to include the results in this report.

GAFTA Analysts Report 2017:1 of 34

4. Where laboratories submitted protein analysis for either sample, Nitrogen correction factors were also requested. In order to compare directly, all protein data for the Feed sample has been converted to use the 6.25 correction factor, All data for the Grain sample has been converted to use a factor of 6.25. Where Nitrogen Factors were not supplied it has not been possible to include protein data in this report.

5. Where results have been reported as “less than” a value, to enable the data to be processed a value of half of the “less than” figure has been used.

6. The assigned value for each analyte was calculated as the robust mean of the trial data once all

relevant corrections for Moisture basis and Nitrogen factor had been applied. For this round, this involved treating any results which lay outside of ± 4 standard deviations (all results) as outliers and recalculating the robust mean value with the outliers removed.

7. The target standard deviation for each analyte was chosen from either the appropriate form of the

Horwitz equation or the trial standard deviation after removal of outliers. The choice was made using current industry practices used in other collaborative trials and proficiency testing schemes. z-Scores were deemed satisfactory if |z| ≤ 2.

8. For Mycotoxin analysis, z scores are for participant information only, to assess their performance against their peers. They are not used by GAFTA to determine eligibility for continued membership.

9. Surplus test materials from this and previous rounds are available for sale. Please email

Homogeneity Assessment

1. Samples were assessed for homogeneity after blending and packing by selecting ten parcels of each material at random from all those produced. Each of these parcels were tested in duplicate under repeatability conditions.

2. Statistical analysis of the resulting data was carried out using the industry standard Cochran’s ‘C’ test and analytical variance test for ‘sufficient homogeneity’.

3. All 3 materials were found to be sufficiently homogeneous for every analyte. 4. Worked example using F1 Protein data.
