CoAg Sampling & Sample Preparation Working Group: YR04 Efforts

MFRPA Alliance and Lab Accreditation MeetingLouisville, KY February 2, 2016Slide2

Overview of Sampling Working Group EffortsPublication of the “Guidance on Obtaining Defensible Samples” (

GOODSamples).Where do I find GOODSamples?What is GOODSamples?Getting the word out! Outreach.

GOODSamplesWhat GOODSamples is and isn’tWhere do I find

GOODSamples?Slide4

GOODSamplesA FDA Cooperative Agreement deliverableAn AAFCO led

collaborative effort with FDA, APHL, AFDO, and industry participationObjective is to improve analytical data equivalency among agenciesGOODSamples outlines the scientific and systematic

approach to

ensure that analytical data generated as a result of a

sampling process is representative of the decision unit and is

defensibleA tool to evaluate current sampling protocolsIs not a summary of current practiceDoes not replace current documentsDoes not provide specific sampling protocolsWhat GOODSample is

What GOODSamples is NOTSlide5

Pilot ProjectsPiloting GOODSamplesSlide11

Sampling PilotsAnticipating four pilotsExploratory conversations with four statesCustomized for each situation

Proposed two options:Two day on-site facilitation for one sampling project. CoAg pays all costs. Four day on-site facilitation with full training course & facilitating multiple projects. Local organization contributes $8500.Slide12
