Cadmium (Cd) contamination of soils is an environmental concern, as cadmium harms food crops and can therefore impact human health. The use of combinations of biochar (seeded with Rhizobium leguminosarum) and Vigna radiata (as an intercrop) has the potential to reduce the mobilization of Cd from soil via mustard plants (Brassica juncea). Mustard plants are grown as a food and oil production crop that is consumed worldwide.

Information on the exposure of wild birds to pharmaceuticals from wastewater and urban refuse is scarce despite the enormous amount of drugs consumed and discarded by human populations. We tested for the presence of a battery of antibiotics, NSAIDs, and analgesics in the blood of white stork (Ciconia ciconia) nestlings in the vicinity of urban waste dumps and contaminated rivers in Madrid, central Spain.

We recently reported that racing greyhound dogs in the USA are infected with A.

The human population is growing and urbanising. These factors are driving the demand for animal-sourced proteins. The rising demand is favouring livestock intensification, a process that frequently relies on antibiotics for growth promotion, treatment and prevention of diseases. Antibiotic use in livestock production requires strict adherence to the recommended withdrawal periods.

Soil heavy metal pollution is one of the most challenging problems. Kenaf is an important natural fiber crop with strong heterosis and a higher tolerance to heavy metals. However, little is known about the molecular mechanisms of kenaf heavy metal tolerance, especially the mechanism of genomic DNA methylation regulating heterosis.

The soil contamination caused by the discharge of cadmium (Cd) from coal mining activities has aroused continuous attention due to the detrimental effects on the human health. This study aimed to investigate the characteristics on distribution of Cd in soils and its accumulation in wheat grains under wheat-cultivation system, and further assess the human health risks to adults and children.

LF3872 was isolated from the milk of a healthy lactating and breastfeeding woman. Earlier, the genome of LF3872 was sequenced, and a gene encoding unique bacteriocin was discovered. We have shown here that the LF3872 strain produces a novel thermolabile class III bacteriolysin (BLF3872), exhibiting antimicrobial activity against antibiotic-resistant Staphylococcus aureus strains.

Skeletal system toxicity due to lead exposure has attracted extensive attention in recent years, but few studies focus on the skeletal toxicity of lead in the early life stages of zebrafish. The endocrine system, especially the GH/IGF-1 axis, plays an important role in bone development and bone health of zebrafish in the early life. In the present study, we investigated whether lead acetate (PbAc) affected the GH/IGF-1 axis, thereby causing skeletal toxicity in zebrafish embryos.

The current development model of the agricultural sector in Brazil has considerable potential to cause negative environmental impacts, including the pollution of aquatic ecosystems, as it may contribute to the intensification of erosive processes on deforested soils, to the leaching of eroded materials, and to the consequent siltation of waterbodies with soil particles containing environmental pollutants.

Purpose To determine if the increase in Cd uptake by durum wheat in the presence of Cd-citrate is due to dissociation or to the transpiration-driven apoplastic uptake of the complex. Methods A mechanistic model of Cd uptake in hydroponics was developed, formalising the transport of Cd, citrate and their complex, including the dissociation of the latter and its uptake

Enrofloxacin (ENR) is one of the most common drugs used in poultry production to treat bacterial diseases, and there is a high risk of drug interactions (DDIs) between polyether anticoccidial drugs added to poultry feed over time. This may affect the efficacy of antibiotics or lead to toxicity, posing a potential risk to the environment and food safety. This study aimed to investigate the DDI of ENR and salinomycin (SAL) in broilers and the mechanism of their DDI.

Mastitis is one of the most prevalent diseases of dairy cows. Currently, mastitis treatment in dairy cows is mainly based on antibiotics. However, the use of antibiotics causes adverse effects, including drug resistance, drug residues, host-microbiome destruction, and environmental pollution. The present study sought to investigate the potentiality of geraniol as an alternative to antibiotics for bovine mastitis treatment in dairy cows.

To date, Cd remains a major contaminant in rice production. An in-depth exploration of the mechanism that causes genotypic differences in Cd enrichment in rice is necessary to develop strategies to regulate Cd enrichment in rice. Here, two rice cultivars (low grain Cd, ZZ143; and high grain Cd, YX409) displayed different transcriptomic profile patterns when subjected to 100μmol/L Cd stress.

The NSAID ibuprofen (2-(4-isobutylphenyl)propanoic acid) and the structurally related 3-phenylpropanoic acid (3PPA), are widely used pharmaceutical and personal care products (PPCPs) which enter municipal waste streams but whose relatively low rates of elimination by wastewater treatment plants (WWTPs) are leading to the contamination of aquatic resources.

Cadmium, one of the toxic heavy metals, robustly impact crop growth and development and food safety. In this study, the mechanisms of wheat (Triticum aestivum L.) selenium-binding protein-A (TaSBP-A) involved in response to Cd stress was fully investigated by overexpression in Arabidopsis and wheat. As a cytoplasm protein, TaSBP-A showed a high expression in plant roots and its expression levels were highly induced by Cd treatment.

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.

Biochar, as a sustainable amendment, effectively remediates soils contaminated with potentially toxic metals. However, the immobilization efficiencies of biochar can vary according to the soil properties.

Edible oil-based switchable-hydrophilicity solvent liquid–liquid microextraction (EO-SHS-LLME) was used prior to the determination of lead as its metal chelate with ammonium pyrrolidine dithiocarbamate (APDC) by flame-atomic absorption spectrometry.

Marine and intertidal heavy metal pollution has been a major concern in recent years. Tachypleus tridentatus has existed on earth for more than 430 million years. It has suffered a sharp decline in population numbers caused by environmental pollution and anthropogenic disturbance for almost 40 years. However, the effects of heavy metal pollution on juvenile T. tridentatus have not been reported.

Wheat (Triticum aestivum) is the second largest grain crop worldwide, and one of the three major grain crops produced in China. Take-all disease, caused by Gaeumannomyces graminis var. tritici (Ggt) infection, is a widespread and devastating soil-borne disease that harms wheat production. At present, the prevention and control of wheat take-all depend largely on the application of chemical pesticides.

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.

Tsetse-transmitted Animal African Trypanosomosis (AAT) is a disease of economic importance to livestock development in Sub-Saharan Africa. The disease is widely managed using trypanocides that are expensive for smallholders and associated with health risks due to drug residues in animal products and drug resistance.

Comprehensive Reviews in Food Science and Food Safety, EarlyView. Pesticides play an important role in increasing the overall yield and productivity of agricultural foods by controlling pests, insects, and numerous plant-related diseases. However, the overuse of pesticides has resulted in pesticide contamination of food products and water bodies, as well as disruption of ecological and environmental systems.

For minor crops such as jasmine, the lack of pesticide registration and maximum residue limits are important issues that need to be solved in order to facilitate trading and ensure food safety. Meanwhile, reliable and quick analytical methods for multi-pesticide residues in these commodities are few, but required by various stakeholders.
