Regulatory Requirements – You are what you eat!<br />
• Ethanol plants need to be aware of process contact with animal<br />
feed<br />
• Chemical products needs to be safe for animal feed<br />
– GRAS (Generally Recognized As Safe) Currently listed in<br />
CFR as GRAS for animal feed 21 CFR 582 or 584.<br />
– Self certified GRAS<br />
• <strong>Nalco</strong> uses Keller & Heckman as third party verification<br />
– CVM (FDA review- not required for compliance with feed<br />
regulations)<br />
• Not all animal rations are created equal (dietary exposure as a<br />
determination of safety is dependent on % use in animal feed, and<br />
the feed consumption factor for individual animal species)<br />
• Approvals are application specific<br />
– It is the intended use of a substance, rather than the substance<br />
itself, that is eligible for GRAS. If a product is GRAS for one<br />
use, it is not necessarily GRAS for all uses.<br />
– Application influences concentration in the final feed due to<br />
varied chemical usage levels, points of application, end<br />
product feed rations.<br />
– Cumulative exposure is also considered.<br />
