Food safety is an important issue that is becoming more and more important due to global trade. EU legislation imposes high demands, in particular on animal products, including honey. Furthermore, residues play an important role in plant products such as tea and herbal teas. Pesticide contamination, in particular, is a recurrent topic here. Exceeding the maximum residue limits or the use of prohibited substances must be verified by regular checks on imported raw materials. QSI carries out thousands of tests on products, such as on antibiotics and pesticides, each year.
