ALTS publishes new assessment scheme for microbiological quality of ice cubes in the gastronomy

ALTS publishes new assessment scheme for the microbiological quality of ice cubes in the gastronomy sector
The Working Group of Experts on Food Hygiene and Food of Animal Origin (ALTS) decided on new recommendations for the microbiological assessment of ice cubes, crushed ice, flake and flake ice from the gastronomy sector at its 95th working meeting from June 23 to 25, 2025.

The aim of the resolution is to harmonize the microbiological testing and assessment of these products. It is based on a schema developed by the ad hoc working group "Crushed Ice," which relies on an extensive data collection from several federal states.

The new assessment scheme sets guideline (m) and warning values (M) for key microbiological parameters:

A deviation from the guideline values (m) indicates possible hygienic deficiencies or weaknesses in the production, storage, or handling of the ice. In such cases, ALTS recommends a review of hygiene practices and, if necessary, cleaning and disinfection of the equipment.

An exceedance of the upper limit values (M) indicates an adverse effect in terms of the Food Hygiene Regulation (LMHV). In these cases, there is a suspicion that the required diligence was not observed in the production, handling, or marketing.

The new scheme aims to ensure a nationwide uniform assessment practice and further strengthen consumer protection in the gastronomy sector.

At BAV Institute, we already apply this assessment scheme recommended by ALTS for evaluating corresponding samples—not only in the gastronomy sector but across industries. This ensures that our microbiological tests are always conducted according to the latest scientific and practical standards. Contact us.
