MYCOTOXINS<br />
Sampling: Critical Point<br />
Ÿ<br />
Quantifying <strong>Mycotoxin</strong> concentration of a maize lot based on<br />
1 sample will give high uncertainty in results<br />
-9<br />
<strong>Mycotoxin</strong>s are measured in nanogram (10 g) of ycotoxin<br />
per gram of RM/Feed (parts per billion or ppb)<br />
In a test procedure conducted by Whitaker et al shows<br />
- Sampling variance of 5 kg sample of shelled<br />
peanuts is 521.4<br />
- Sample preparation variance is 59.2<br />
- Analytical (TLC) variance is 50.1<br />
The Variance in results can be reduced by obtaining a<br />
representative sample correctly and using more sensitive<br />
analytic methods<br />
Obtaining a representative sample of feed or grains<br />
Collect from different points from<br />
- Moving stream of feed/grains<br />
- From silos<br />
- From truck<br />

1 ppb is equal to 1 second in 32 years or 1 drop of water<br />
