Hi everyone, was hoping to get some guidance on recent tests results. My company packs and seals agglomerated powder blends for our beverage machine. Recently, we sent out 50g samples to an outside lab for microbial analysis of 3 powders. My concern is the APC results & mold. Our customer indicated the following acceptable limits for APC & Mold:
Total count : <1.000 cfu/g
Yeasts & Molds : <100 cfu/g
Our results came out to be: Sample 1 APC 50 (est) cfu/g. Sample 2 APC 40 (est) cfu/g Mold 90 (est) cfu/g
These powders were not run through our machines yet, they were only agglomerated at our partner facility next door. As these are 50g samples, should there be a large concern? I've been trying to find research on acceptable limits based on sample sizes, so any guidance would be appreciated. Thank you!
