As a general guideline, the Aerobic Mesophilic Count of spray dried coffee, coffee mixtures and surrogates must not exceed 500 cfu/g and freeze dried coffee must not exceed 3000 cfu/g. These are limits set by Nestle.
However there are some countries which have local regulatory norms for microbiology of coffee which could be lower than Nestle‘s limits. In this case the strictest applies. This is important information especially for inter market supply and must be included in the Inter Market Supply brief.
