The AOAC Agricultural Materials Community Feed Additives and Contaminants Subgroup focus is the prioritization, development and validation of analytical methods for feed additives and contaminants.

The subgroup projects proceed through an established program of work which includes: getting stakeholders identified and involved, establishing method performance criteria, developing a list of potential methods and experts, assigning project leader/study director, obtaining plan approval, carrying out a collaborative study, evaluating data and obtaining final approval, publishing and disseminating approved methods, following up, and identifying financial support. 

The activities of the group will be presented and progress in the various methods reported.  Method needs were reprioritized in 2006. 

Based on the prioritization process, method projects now underway include feed methods for lasalocid, oxytetracycline, multi-analyte mycotoxin screen, multi-analyte mineral, decoquinate, chlortetracyline, neomycin, and vitamin A. 

In addition, volunteers to draft method needs statements have been recruited for vitamins D & E, bacitracin, virginiamycin, tylosin, amprolium, carbadox and melengestrol acetate. 

A call for methods is currently out for a multi-analyte mineral method and for a chlortetracycline method.
