Pesticides are chemicals used to treat plants and eliminate threats to their growth. They are used worldwide and are divided into subgroups depending on their usage: herbicides (against weeds), insecticides (against animal pests), and fungicides (against fungi). The usage of pesticides as well as the maximum amount of residue on and in food products are regulated by numerous laws. Most importantly, the EU-Regulation 396/2005 is utilized for the assessment of maximum residue levels. Furthermore, for organic food products, the valid regulations are (EC) No. 834/2007 (the organic-product-regulation) and (EC) No. 889/2008. We offer comprehensive consulting and analytical services for numerous product groups, such as fruit, vegetables, tea, and spices.
