Lycium barbarum L., also known as goji berry, is popular in China and across the world as both a food and a medicine. The pervasive use of chemical pesticides has led to widespread contamination of raw goji berries, although the impacts of pesticide contamination on goji berry-derived products have not yet been thoroughly characterized.

The aim of this study was to compare the results of the presence of antibiotic (AB) residues in the milk of dairy cows treated with ABs – during the withdrawal period (WP) and after the WP obtained by various screening tests (Delvotest T, Twinsensor BT020, and Eclipse 50), to evaluate the presence of AB residues with regard to selected factors (indication for AB administration, AB group, and a number of antimicrobial substances) and to assess selected parameters of milk quality (fat, crude pr

This study examined the distribution of 37 pesticide residues in different cereal grains (rye, wheat, oat, and barley) and their fractions, including flour, bran, and feed bran. The grains used in the study were sprayed in the field before processing to provide a more accurate representation of the fate of pesticide residues in these fractions. Pesticides were extracted using the QuEChERS method and analyzed by GC-MS/MS and LC-MS/MS.

The prevalence of pesticide usage has brought the matter of pesticide residues to the forefront, necessitating the development of effective detection methods as a crucial step towards addressing this issue. This study presents a novel approach for detecting pesticide residues in vegetables using glass slide-formula-ion mobility spectrometry (IMS). The approach enables swift analysis of 36 different pesticides across three vegetable species with glass slides.

Processed meat products could constitute a relevant source of cadmium (Cd) and other toxic elements in the diet as they could contain organ meats (e.g. kidneys, liver) known to accumulate metals. Additionally, these products could be contaminated due to metal transfer from the machinery during processing and, in the case of canned meats, metal migration from the container could also occur.

The presence of pesticide residues in vegetables is a worldwide issue regarding food safety. This study explores the efficacy of a novel advanced oxidation process (AOP), namely the coupled ultrasonic-ozonation (US/O3) process, for removing six commonly found pesticides from vegetables.

Population growth, international market expansion, and climate change have caused changes in agricultural practices, including increased use of phytosanitary products to control pests and diseases in food production. The European Union aims to achieve sustainable and high-quality food, with the priority of reducing pesticide use.

Arsenic (As) is absorbed and accumulated during the growth of crops, resulting in elevated As concentrations in agricultural products, and threatening human health. Considering As toxicity is associated with chemical species, this review outlines the available literature on both total As and its species in agricultural products. The review reflects that inorganic As was the dominant species in cereal grains (42%–98%) and vegetables (84.2%–100%), the As species in mushrooms are diverse.

Heavy metal ions (HMIs) and arsenic ion with high bioavailability and toxicity in seafood pose a serious threat to human health by food chain.

Quality and safety issues arising from herbicide residues in fishery products are a growing concern. In order to ensure the edible safety of fishery products, a comprehensive assessment of multi-class herbicide residues should be conducted. Hence a modified QuEChERS approach was explored and validated using UPLC-Q-Tof-MS/MS for rapid screening and quantification of 158 herbicide residues in fishery products.

Antibiotic residues in chicken meat pose health risks to consumers and affect the economics of the poultry industry due to an export ban. The present cross-sectional study aimed to determine the occurrence of antibiotic residues in marketed chicken meat collected under different agro-climatic conditions in Chhattisgarh, India, and assess human health risks by Monte Carlo Simulation.

A liquid chromatography-high resolution mass spectrometry (LC-HRMS) method for screening, quantification and identification of veterinary drugs (antibiotics, nonsteroidal anti-inflammatory drugs, anthelmintics, coccidiostatics and tranquilizers) and pesticide residues was validated in pig (porcine) muscle.

This study was carried out to detect pesticide residues in tropical fruits. QuEChERS method was validated to determine 301 different pesticides in high water content commodities and high acid content commodities by liquid chromatography-tandem mass spectrometry (LC–MS/MS) and gas chromatography-mass spectrometry (GC-MS). Matrix effects were determined for all pesticides in banana, blueberry, lime, mango, and pineapple.

Polychlorinated biphenyls (PCBs), a class of synthetic organic compounds consisting of chlorine atoms on two coupled biphenyl rings, have been declared class A carcinogens by the World Health Organization. Here, we report a new method for the determination of PCBs content in chicken.

National and international food and feed safety authorities are shifting from routine-to risk-based monitoring. Risk-based monitoring requires flexibility in the scope of analytes, matrices, and sampling. Also, risk-based monitoring implies a desire for retrospective analysis using different scope(s) to follow trends, identify new food safety threats, and monitor the effectiveness of policy interventions.

In the present study, the effects of intermittent ozone (IO3) application combined with low dose fungicide and high-dose dissolved ozone in water on storage life and quality of orange cv. Washington Navel were investigated.

The aims of this study were to: i) analyze the prevalence and concentration of pesticides belonging to 4 major classes, namely organochlorines, organophosphates, carbamates and pyrethroids in chicken meat, liver and kidney; ii) evaluate the impact of boiling, frying and freezing on pesticide levels in chicken meat, and iii) estimate the dietary exposure to pesticide residues in chicken meat and conduct a risk assessment.

As a first-time study, the thermal storage stabilities of pesticides (bifenthrin, carbofuran, diazinon, methomyl, triflumuron, triadimenol, triazophos, and thiabendazole) in banana homogenate were investigated. Pesticides-spiked banana samples were stored at −20 °C (T1), 4 °C (T2), 25 °C (T3), and 40 °C (T4) and the residues were observed from day 0 to day 84.

The goal of the present study was to estimate the distribution and migration of eleven systemic and non-systemic pesticides between the skin and the pulp of apples. Additionally, the behaviour of acetamiprid, boscalid, bupirimate, cyprodinil, flonicamid, fluopyram, pirimicarb, pyrimethanil, thiacloprid, deltamethrin, and fludioxonil in two apple varieties during four thermal processes ranging between −40 °C and 150 °C was discussed.

In 2004, the Food Code of Korea adopted a multi-class multi-residue pesticide analysis method, which employed liquid–liquid extraction (LLE) and solid-phase extraction for sample purification. After several modifications, the LLE stage was replaced by the QuEChERS method in October 2021. Thus, in the current study a comparison was carried out between the new QuEChERS method and the conventional LLE method for the simultaneous analysis of multiple pesticide residues.

An ultrasound-assisted acetonitrile extraction method was applied for the determination of 43 pesticide residues in intact grape berries (Vitis Vinifera L.) by liquid chromatography-tandem mass spectrometry (LC–MS/MS). The results showed that ultrasound-assisted extraction from intact grape berries exhibited better efficiency than extraction from homogenized grape berries.

Vegetables and fruits may contain pesticides, leading to several health complications after long-term exposure.
