The working group "Microbiological guideline and warning values" of the DGHM (German Society for Hygiene and Microbiology) has adopted a recommendation for frozen fruit and two drafts for dried fruit/fruit powder and dried mushrooms.
For frozen fruit, the draft from August was adopted at the last meeting of the working group in November and from now on can only be obtained as a "recommendation" for a fee from Beuth-Verlag. We had already informed you about this and other drafts of the working group in the AGROLAB RADAR October issue.

The recommendations of the DGHM are not binding. Drafts of new recommendations are published for comment on the DGHM website, to which we hereby refer as a source for the above tables. The DGHM recommendations may deviate from the original drafts. After publication, they can only be obtained for a fee from Beuth-Verlag.
YOUR PLUS:
When assessing microbiological findings, we follow the recommendations of the DGHM if no other legal rules apply and display these on our analysis reports as additional information for our customers.
