b) If the guideline value is exceeded, the sensory analysis must be included in the assessment.

c) For the examination and assessment of Listeria monocytogenes, the requirements of Regulation (EC) No. 2073/2005 on microbiological criteria for foodstuffs, as amended, must be observed. In addition to this, the provisions of Article 14 of Regulation (EC) No. 178/2002 in the currently valid version may be consulted.

If live microorganisms are added as a starter culture, or ingredients such as cheese or yoghurt are used that contain live organisms, this must be taken into account in the assessment.
b) If raw plant ingredients are added, this must be taken into account in the assessment.
c) If the guideline value is exceeded, the assessment must also include a sensory analysis.
d) For the examination and the evaluation of Listeria monocytogenes, the requirements of Regulation (EC) No. 2073/2005 on microbiological criteria for foodstuffs in the currently valid version must be observed. In addition to this, the regulations from Art. 14 of Regulation (EC) No. 178/2002 in the currently valid version can be used.

 

All information without liability

 

DGHM recommendations are not legally binding. They serve as a guide for industry, but are also used in the assessment of food due to the lack of legal requirements. The currently valid DGHM recommendations must be purchased from Beuth-Verlag Link: https://www.beuth.de/

 

YOUR PLUS: We base our evaluation of microbiological findings on the DGHM recommendations if no other legal regulations are applicable and we indicate this on our analysis reports as additional information for our customers.
