Mechanism of how anti‐microbial resistance is acquired through food and food residues. Summary Residue and resistance in food animals pose significant challenges to Southeast Asia's public health, animal welfare, agricultural productivity, and sustainability. This article emphasises the need for policy interventions to address these issues effectively. Residue, the presence of harmful substances in animal products, is a concern due to the misuse of veterinary drugs and pesticides.

This study demonstrates that Cinnamomum camphora essential oil (CEO) effectively inhibits Fusarium oxysporum‐induced decay in postharvest blueberries by disrupting fungal cell membrane integrity and enhancing blueberry defence mechanisms. The findings suggest that CEO, as an eco‐friendly alternative to synthetic fungicides, can mitigate primary fungal invasion and improve blueberry preservation during postharvest storage.

Abstract Conventional food preservation methods such as heat treatment, irradiation, chemical treatment, refrigeration, and coating have various disadvantages, like loss of food quality, nutrition, and cost‐effectiveness. Accordingly, cold plasma is one of the new technologies for food processing and has played an important role in preventing food spoilage. Specifically, in‐package cold plasma has become a modern trend to decontaminate, process, and package food simultaneously.

This study explored the impact of aqueous ozone treatment on chlorpyrifos degradation in cucumbers, optimizing conditions using both response surface methodology (RSM) and artificial neural network‐genetic algorithm (ANN‐GA). While both models demonstrated high predictability, the ANN optimized conditions surpassed RSM in chlorpyrifos degradation, resulting in enhanced physicochemical and microbial qualities in cucumbers.

Green and blue molds and sour rot, caused by Penicillium digitatum, P. italicum, and Geotrichum citri-aurantii, are postharvest diseases which represent an important economic issue in lemon production. Conventionally, their control involves the intensive use of synthetic fungicides, leading to the emergence of resistant strains and harmful residue accumulation on fruits.

Abstract Background Understanding the role of adjuvants in pesticide persistence is crucial to develop effective pesticide formulations and manage pesticide residues in fresh produce.

Food chain contamination by soil lead (Pb), beginning with Pb uptake by leafy vegetables, is a threat to food safety and poses a potential risk to human health.

Abstract The marine finfish and crustaceans contribute immensely to human nutrition. Harvesting marine food‐fish to meet the global demand has become a challenge due to reduction of the fishery areas and food safety hazards associated with increased pre‐harvest and post‐harvest contaminations. The causes of low fish availability and contaminations were reviewed following the published literature from 2000 to 2023.

Environmental quality and food safety is threatened by contamination of lead (Pb) and cadmium (Cd) heavy metals in agricultural soils. Therefore, it is necessary to develop effective techniques for remediation of such soils. In this study, we prepared iron-modified biochar (Fe-BC) which combines the unique characteristics of pristine biochar (BC) and iron.

Effects of electrolyzed water‐ultrasound treatments on pesticide removal in fresh‐cut potatoes with different cutting methods. Abstract Electrolyzed water (EW) and ultrasound (US) treatment are emerging effective means of reducing pesticides in fresh‐cut vegetables. However, their synergetic efficacy of degrading pesticides in fresh‐cut potatoes has not yet been revealed.

Pesticide use has grown rapidly in West Africa over the past decades. Regulatory capacity has not kept pace with the rapid proliferation of pesticide products and on-farm use. As a result, health and environmental impacts from the growing use of pesticides, despite their potential importance to food safety, remain largely unmonitored, underreported, and poorly understood by key stakeholders.

Fungicides are often used to extend the storage time of postharvest satsuma mandarin fruit. In recent years, fungicide residue has become an issue of food safety. This study aimed to investigate the distribution and migration of three typical fungicides (imazalil, prochloraz, thiophanate-methyl) in postharvest satsuma mandarins using liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Arsenic (As) contamination in agricultural soils has become a great threat to the sustainable development of agriculture and food safety. Although a lot of approaches have been proposed for dealing with soil As contamination, they are not practical in crop production due to high cost, time-taking, or operational complexity. The rapid development of nanotechnology appears to provide a novel solution to soil As contamination.

Fabric-phase sorptive extraction (FPSE) coats organic–inorganic hybrid sorbent materials onto flexible and hydrophilic fabrics through sol–gel sorbent-coating technology. Herein, we explored four different coating chemistries, including those of nonpolar sol–gel poly(dimethylsiloxane), medium polar sol–gel poly(tetrahydrofuran), and polar sol–gel poly(ethylene glycol) (PEG)–block-poly(propylene glycol)–PEG, and sol–gel PEG.

Atrazine (ATZ) is an agricultural pesticide for controlling field weeds. ATZ accumulates in many crops, posing high risks to crop production and food safety. Characterizing one of the novel rice MT genes named Oryza sativa atrazine-responsive methyltransferase (OsARM) showed that the expression of OsARM was associated with DNA demethylation (hypomethylation) in its promoter region.

Herein, we explored four different coating chemistries, including those of nonpolar sol–gel poly(dimethylsiloxane), medium polar sol–gel poly(tetrahydrofuran), and polar sol–gel poly(ethylene glycol) (PEG)–block-poly(propylene glycol)–PEG, and sol–gel PEG.

Due to the biomagnifying effect in the food chains, heavy metals will cause serious harm to the food produced in paddy soil, and then threaten human health. The remediation of soil heavy metals by the addition of amendments is a common method. However, the combination of the two amendments has been less studied and its effect is unknown.

Abstract

The industrialization of the agri-food industry and resultant decrease in the number of people employed on farms has contributed to a knowledge gap among consumers about food production processes. A commonly reported concern of dairy consumers is the use of antibiotics in dairy animals, even though these drugs are an important tool for promoting animal health and welfare and food safety.

For decades antibiotics have been used in poultry rearing to support high levels of production. Nevertheless, several problems have arisen because of the misuse of antibiotics (i.e., antibiotic resistance, residues in animal products, environmental pollution). Thus, the European Union (EU) as well as the European Food Safety Authority (EFSA) promote action plans to diminish the use of antibiotics in animal production. Alternatives to antibiotics have been studied.

Aquaculture has undergone rapid development in the past decades. It provides a large part of high-quality protein food for humans, and thus, a sustainable aquaculture industry is of great importance for the worldwide food supply and economy. Along with the quick expansion of aquaculture, the high fish densities employed in fish farming increase the risks of outbreaks of a variety of aquatic diseases.

A pot experiment was conducted to investigate the effects of 0.5% and 1% alkaline, clay mineral and phosphorus amendments, as well as 2% and 5% organic amendments, on lead (Pb) soil bioavailability and Pb absorption by the low-Pb accumulator kumquat (Citrus japonica Thunb.) ‘Cuipi’ in two typical Pb-contaminated soils, Jiyuan and Yangshuo, from northern and southern China, respectively.

The aim of the present study was to evaluate the contamination levels of some classes of persistent organic pollutants (POPs) in free-range hen eggs and to estimate the related human dietary exposure in a Site of National Interest (SNI), characterized by a serious state of environmental pollution (Bussi sul Tirino area, central Italy).

The input of heavy metals in agricultural systems depresses the soil quality and compromises the food safety owing to crop contamination. Metals also affect the structure, morphology, function, and activity of microorganisms in soils and substrates. Heavy metals can inhibit basic processes of microbial metabolism such as respiration.
