As aforementioned, the development of wide-scope multiresidue methods able to cover the analysis of pesticide and VD residues in feed is a current need due to the gap that exists in this area of feed safety. Consequently, in this work, an UHPLC–QqTOF–MS method has been developed for simultaneous determination of a huge number of target pesticides and VD residues in feed. A generic sample procedure followed by a simple clean-up step by Florisil cartridges was selected as the most appropriate for the analysis of the wide range of compounds in feed in terms of recovery yields and matrix effect. The developed method allows the analysis of an average of 200 residues of different families of pesticides and VDs in various feed. The developed method was validated according to Directive 2002/657/CE and Document SANCO 12495/2011; it showed good quantitative results for most of the studied compounds and the LOQs range from 4 to 200 μg kg−1. Despite the variety of compounds that could be determined by the current method, further experiments are needed to include the analysis of tetracyclines, quinolones, avermectins and penicillins, which could not be determined with this method. Although the sensitivity attained by the proposed method was lower than some of published methods, it was enough to comply with MRLs established by EU. Finally, the method was applied to different kinds of feed demonstrating its applicability as quantitative method in any type of feed. This method illustrated the feasibility of using QqTOF for detecting, identifying and quantifying pesticides and VDs residues in a multi-class method. In spite of the advantages showed by the proposed method, it shows some limitations due to some families of VDs, such as tetracyclines,quinolones and penicillins, which are not properly extracted. Furthermore, the proposed method showed low sensitivity making the detection of some compounds and fragments at low concentrations unfeasible.
