AOAC Method SMPR 2015.013 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Detection of Staphylococcal Enterotoxin B (SEB)

AOAC SMPR 2015.013 defines the minimum performance requirements for detecting Staphylococcal Enterotoxin B (SEB) in liquid food matrices such as bottled water, milk, juices, liquid egg, cooked chicken, and canned vegetables. The method must detect SEB at or below the acceptable minimum detection level (AMDL) of 0.25 ng/mL with a probability of detection (POD) of 95% or greater. It must distinguish SEB from ten non-target staphylococcal enterotoxins—SEA, SEC1–3, SED, SEE, SEH, SEI, SEJ, and SEK—each tested at ten times the AMDL. The system false-negative and false-positive rates must be ≤ 5%. In addition, the total assay time from recovery to result must not exceed two hours to support timely decision-making in both laboratory and field deployments.

Each method must include proper positive and negative controls to ensure sensitivity and specificity. Instruments must support ELISA or other immunoassay platforms that allow for traceable validation, consistent results, and appropriate control monitoring. Acceptable methods must demonstrate strong selectivity and avoid cross-reactivity, especially when tested with environmental matrix interferences. All protocols must meet AOAC guidance for validating biological threat agent methods. The systems listed below fulfill these criteria and support AOAC-compliant workflows for SEB detection in high-priority testing environments.
