Does anyone know what the pesticide maximum residue limits are for dried brewer’s yeast in the US? Brewer’s yeast is the leftover yeast from beer fermentation/production that is separated and dried. Although separated from the beer/barley, there can be residual pesticides from the barley present in the dried yeast. Since EPA pesticide limits are based on agricultural crops, I'm couldn't find any limits for yeast. I did find the FDA has yeast on their pesticide import alert 99-08, so there should be limits for yeast. Would barley be the agricultural crop used to determine what pesticides are allowed in dried brewer’s yeast? Or would the dried brewer’s yeast only have the tolerances associated with processed foods? Pesticide limits 40 CFR 180: https://ecfr.io/Titl...t Alert 99-08: https://www.accessda...talert_259.html
