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

Unfortunately for you, the answer is no, the limits are NOT the raw crop limits and they may have been elevated to higher limits during the process  i.e. any bromide left in the kettle has not disappeared just because it's not in the beer.......it's now all in the byproduct aka brewers yeast

 

These are the lists and limits for "food" which your product is

Please stop referring to me as Sir/sirs

Thanks for the response!

 

The link sends me to the start of 40 CFR 180. Is there a specific part it should have sent me to?
