Sample #141864
Test Method MCFU (CFU/g) LOD (CFU/g) Status (CFU/g)
Total Aerobic Not Tested N/A 0 Not Tested
Yeast & Mold Not Tested N/A 0 Not Tested
Bile-tolerant gram-negative bacteria Not Tested N/A 0 Not Tested
Total Coliforms Not Tested N/A 0 Not Tested
E. Coli Not Tested N/A 0 Not Tested
Salmonella Not Tested N/A 0 Not Tested
Aspergillus spp. Not Tested N/A 0 Not Tested

Sample passes for Total Aflatoxins [sum of B1, B2, G1, and G2] (Action Limit ? 20 ppb; MDL = 10.778 ppb). Sample passes for Ochratoxin A (Action Limit ? 20 ppb; MDL = 9.259 ppb). Method = FE-68 [ELISA]; Expanded Method Uncertainty = 28% [K=2]. MDL = Method Detection Limit.

TNTC = Too Numerous To Count. Maximum Colony Forming Units (MCFU) represents the minimum value that a test would need to achieve in order to be considered a failed result (if applicable). LOD is the Limit of Detection for the method. CFU/g = Colony Forming Units per gram. Aspergillus spp. consists of A. flavus, A. fumigatus, A. niger, and A. terreus.

Sample was sampled and tested in accordance with the Safety Compliance Facility Sampling and Testing Information.
