This study developed and validated an analytical method for simultaneous identification quantification of 41 veterinary drugs in honey using liquid extraction (LLE) chromatography coupled to quadrupole-Orbitrap high-resolution mass spectrometry (LC-Q-Orbitrap HRMS). The was accordance with Commission Implementing Regulation (CIR) EU 2021/808 at five different concentrations ranging from 0.075 50 μg/kg. mean recoveries ranged 70 105, while repeatability values were all below 17%. linearity,...
Nile tilapia (Oreochromis niloticus) samples were collected at monthly intervals between July 2018 and June 2019 from 3 sampling sites (El-Rahawy, Sabal Tala) situated along the Rosetta branch of Nile, Egypt, to monitor presence 100 pesticides 5 antibiotics using different extraction procedures followed by GC–MS/MS LC–MS/MS. Potential human health risks via consumption contaminated fish was also assessed. Of 72 analyzed muscle samples; 86% 21% with antibiotics, respectively. Chlorpyrifos...
From the Rapid Alert System for Food and Feed (RASFF) database, a total of 4728 notifications regarding six most frequently notified heavy metals (i.e., arsenic, cadmium, lead, mercury, chromium, nickel) were tracked from January 1, 2000, to December 31, 2022, analyzed based on year, notification classification, notifying countries, countries origin, product types, categories, risk decision, action taken. Human assessment owing consumption mercury- cadmium-contaminated seafood was estimated...
Abstract From 2000 to 2022, all and serious notifications of the EU Rapid Alert System for Food Feed (RASFF) on herbs spices were examined identify most notified products, their associated hazards origin countries, as well consequent notification classification actions taken. The data reveals that 3741 transmitted during last 23 years, accounting 5.3% RASFF total product categories (70630). Border rejection risk decisions represented 37.9% 39.5% notifications, respectively. In 5 ranged from...
Abstract Honey is regarded as natural and healthy. However, a variety of contaminants could be present in the areas production. The study aimed to identify top hazard categories Rapid Alert System for Food Feed (RASFF) notifications honey from 2002 2022, taking into account notification year type, country origin, notifying country, risk decision, actions taken. All RASFF were processed Pivot tables using Microsoft Excel. Out 388 last 21 years 309 (79.64%) concerned unauthorized residues...
This study focused on evaluating and optimising the liquid-liquid extraction (LLE) method for multi-residue analysis of seven AGs in bovine liver, meat, milk, kidney conjunction with liquid chromatography coupled to a quadrupole-Orbitrap high-resolution mass spectrometry (LC-Q-Orbitrap HRMS) quantification. Of all hydrophilic interaction (HILIC) stationary phases tested, ZIC-HILIC column yielded best performance. The was validated according Commission Implementing Regulation (CIR) EU...
