How many good and healthy substances are contained in the samples? Is it possible that harmful bacteria or toxins have got into them? Do the samples contain as many healthy contents as the advertising promises?

Residue analysis at a trace level
LEON offers you a wide range of residue tests, so that your products are safe for the German and international market.

Whether your products are fruit, vegetables, grains, meat, milk, cheese, water or tea – you, as the dealer or producer, have a fundamental interest in knowing the extent to which your goods could be contaminated with pesticides, pyrrolizidine alkaloids, heavy metals, mycotoxins or other harmful substances. For there are strict regulations regarding limit values and guideline values in the EU. In addition, the consumer also has an increasing interest in and awareness of these issues.

Microbiological tests
Microorganisms may lead to the spoiling of food and, in the worst case, may pose a danger for the consumer. The LEON laboratory gives you and your customers the certainty that you are only putting products that are safe for the consumers’ health into circulation. We also carry out hygiene checks of the ambient air, the work areas and surfaces and verify the effectiveness of cleaning measures.
