AOAC RESEARCH INSTITUTE 

Expert Review Panel Chair Report for Microbiology for Foods and Environmental Surfaces 

Page 6 of 8 

In regards to multiple and unique test portion sizes, and alternate enrichments, the ERP discussed that the 

information be considered on a case by case basis.  However, it was noted that this information should be 

captured for future use and the tracking of exceptions regarding sample sizes, etc, should be noted.   

 If r PTM AND OMA testing?  Example: The method developer wants to claim 375g. 

The ERP discussed that the use of the 5 new 

Listeria 

species in the inclusivity studies, the ERP suggested that 

it should be included in the study, wherever available.   

The ERP discussed available information regarding the use of the alternative collaborative study design for 

expensive equipment.  It was noted that ISO 16140 and AOAC  Appendix I: AOAC INTERNATIONAL Methods 

Committee Guidelines for Validation of Biological Threat Agent Methods and/or Procedures, both allow for 

up to three collaborators in the same laboratory, as long as it is independent with separate sample sets.  

However, AOAC

Appendix D: Guidelines for Collaborative Study Procedures to Validate Characteristics of a 

Method of Analysis

allows for up to five collaborators.
