Abstract

Veterinary drugs play a crucial role in the treatment of various animal diseases. However, their residues, stemming from issues, such as withdrawal period lapses, overuse, or abuse, can jeopardize food safety and human health. This study addresses recent regulations in Korea concerning specific veterinary drugs (anacolin, ephedrine, menichlopholan, piperonyl butoxide, and etisazole HCl) and their ongoing discussions. This study aimed to validate two pre-developed methods for quantifying residues in livestock and fishery products using QuEChERS and liquid chromatography-tandem mass spectrometry. Both methods exhibited excellent linearity, recoveries (70.3–119%), and coefficient of variations (1.3–28%), along with low limits of detection and quantification (0.3–4 ng/g and 1–12 ng/g). This study is significant for its contribution to the detection of veterinary drugs in livestock and fishery products, given the limited research available on the methods for analyzing these substances. • Two methods to quantify certain veterinary drugs were developed. • Before providing the method, validation was performed according to CODEX criteria. • This study evaluated the applicability of these methods to animal-derived products. • These methods are expected to be useful for residues for food hygiene.

Abstract

The effects of various washing procedures, including stagnant, running, and stagnant and running tap water, and the use of washing solutions and additives, namely NaCl (1% and 2%), vinegar (2%, 5%, and 10%), detergent (0.5% and 1%), and charcoal (1% and 2%), on the reduction rate of diethofencarb were estimated in field-incurred crown daisy, a model of leafy vegetables, grown under greenhouses located in 3 different areas (Gwangju, Naju, and Muan). The original Quick, Easy, Cheap, Effective, Rugged, and Safe “QuEChERS” method was modified for extraction and liquid chromatography–tandem mass spectrometry (LC/MS/MS) was used for analysis. The recovery of diethofencarb in unwashed and washed samples was satisfactory and ranged between 84.28% and 115.32% with relative standard deviations (RSDs) of <6%. The residual levels decreased following washing with stagnant, running, and stagnant + running tap water (i.e., decline in levels increased from 65.08% to 85.02%, 69.99 to 86.79, and 74.75 to 88.96, respectively). The percentage of decline increased and ranged from 77.46% to 91.19% following washing with various solutions. Application of 1% detergent was found to be the most effective washing method for reducing the residues in crown daisy. Additionally, washing with stagnant and running tap water or even stagnant water for 5 min might reduce the residue levels substantially, making the prepared food safe for human consumption.
