MULTIRESIDUE SCREENING OF PESTICIDES AND THEIR RECOVERY FROM FATTY FOOD MATRICES USING THE QUECHERS METHOD
Published: 1 Jun 2014
Abstract: Although the use of organochlorine pesticides was banned in European Union states, these pesticide residues continue to be present in the environment. These residues enter the human body via diet, therefore it is necessary to monitor their levels in food. This study investigates the presence of selected organochlorine pesticides in representative high-fat dairy products using the QuEChERS method. All of the tested dairy products had lower levels of the pesticides than the currently permitted limits. Effect of the fat content in high-fat dairy products on the recovery of organochlorine pesticides using the QuEChERS method was also investigated. High-fat food matrices had a negative impact on the recovery of most of the tested organochlorine pesticides.
