Using alternative ingredients or low-quality grain grades to reduce feeding costs for pig diets can introduce mycotoxins such as deoxynivalenol (DON) into feed, which is known to induce anorexia, inflammation, and oxidative stress. Adding vitamin 25(OH)D3 or vitamins E and C to the feed could increase piglets’ immune system to alleviate the effects of DON.

This study aimed to protect maize crops from infection and production of Aspergillus flavus (A. flavus) aflatoxin B1(AFB1), using the ordinary and nanoscale extracts of Agaricus spp. HPLC technology showed that the isolate taken from Musayyib district which coded with (AFA5) was a highest toxin producer.

Mycotoxins, especially aflatoxin B1 (AFB1) and fumonisin B1 (FMB1), are common contaminants in cereal-based foods. Instances of contamination are predicted to increase due to the current challenges induced by climate change. Despite the health benefits of whole grains, the presence of mycotoxins in bran remains a concern. Nonetheless, previous research indicates that wheat bran can adsorb mutagens.

Aspergillus flavus and its carcinogenic secondary metabolites, aflatoxins, not only cause serious losses in the agricultural economy, but also endanger human health. Rhein, a compound extracted from the Chinese herbal medicine Rheum palmatum L. (Dahuang), exhibits good anti-inflammatory, anti-tumor, and anti-oxidative effects. However, its effect and underlying mechanisms against Aspergillus flavus have not yet been fully illustrated.

Background One of the most carcinogenic compounds found in milk is aflatoxin M1 (AFM1), which is formed in lactating mammals after the ingestion of feeds that have been contaminated with aflatoxin B1 and then excreted into milk. As such, AFM1’s concentration is limited at the both the national and international levels by national legislation or internationally-adopted Codex Alimentarius standards, respectively.

Fresh maize kernels are dried to reduce post‐harvest food loss while preserving product quality. Performance and quality are analyzed together in a 4E analysis and quality assessment (4E + Q analysis) being vital for evaluating the drying system's impact on product quality. Abstract The world's population is projected to increase, impacting a 60% rise in food production demand by 2050, including the demand for maize.

This study developed an affordable electrochemical sensor using thin MXene sheets for aflatoxin B1 (AFB1) detection. MXene was etched to form single or small layers, and a paper electrode was created via vacuum filtration. The sensor, with specific aptamer modification, showed wide detection range, selectivity, and reproducibility in detecting AFB1 in real samples.

Maize (Zea mays L.) stands as a vital staple food globally, holding significant nutritional and economic value. However, its susceptibility to mycotoxin contamination under stressful environmental conditions poses a considerable concern. This study aimed to assess the quality and pasting characteristics of maize varieties across two distinct regions and examine the occurrence of mycotoxins influenced by climatic factors.

Aflatoxin B1 (AFB1) is a prevalent mycotoxin present in feed ingredients. In this study, we investigated the effects of Lactobacillus salivarius (L. salivarius) on the Landes geese exposed to AFB1.

Vegetable oils are essential constituent of the daily dietary intake. Nevertheless, they often contain aflatoxin B1 (AFB1) and benzo(a)pyrene (BAP). Physical adsorption is the most commonly used detoxification method in the vegetable oils industry. Regrettably, the previously reported adsorbents have exhibited limited efficacy, rendering them inadequate for meeting the requirements of large-scale production of edible oils.

Aflatoxin B1 (AFB1) is an unavoidable environmental toxin. The accumulation of AFB1 and its metabolites in the liver poses a threat to both human and animal health. Curcumin exhibits anti-oxidative, anti-tumor, and anti-inflammatory properties. There is no report on the mechanism regarding how curcumin relived liver necroptosis in chickens induced by AFB1 based on the regulatory network of ceRNA.

Aflatoxin B1, a major global food safety concern, is produced by toxigenic fungi during crop growing, drying, and storage, and shows increasing annual prevalence. This study aimed to detect aflatoxin B1 in chili samples using ATR–FTIR coupled with machine learning algorithms. We found that 83.6% of the chili powder samples were contaminated with Aspergillus and Penicillium species, with aflatoxin B1 levels ranging from 7.63 to 44.32 µg/kg.

Ochratoxin A (OTA) is one of the mycotoxins in the agriculture and livestock sectors. The poultry sector suffered from significant economic losses due to the adverse impacts of OTA on the growth rate, feed conversion ratio, and livability. Thus, the present investigation aimed to determine the impact of chamomile essential oil supplementation against OTA toxicity in growing quails. 360 one‐week‐old growing quails were distributed into six groups (n = 60) with four replicates of 15 birds.

Fusarium head blight (FHB) is a destructive disease caused by several species of Fusarium, such as Fusarium graminearum and F. asiaticum. FHB affects cereal crops, including wheat, barley, and rice, worldwide. Fusarium-infected kernels not only cause reduced yields but also cause quality loss by producing mycotoxins, such as trichothecenes and zearalenone, which are toxic to animals and humans.

Potato dry rot is a global problem caused by Fusarium species. Symptoms of dry rot include wrinkled brown to black patches of tissue. Fusarium spp. infection in potato tubers results in the formation of mycotoxins. Fungi that cause dry rot are commonly Fusarium sambucinum and Fusarium solani.

The intestinal epithelium performs essential physiological functions, such as nutrient absorption, and acts as a barrier to prevent the entry of harmful substances. Mycotoxins are prevalent contaminants found ...

The levels of patulin contamination in fruit juices showed a discernible decline from 2014 to 2022 within the Chinese market. According to risk assessment, the average daily intake of patulin did not present a threat to public health. Summary Excessive patulin contamination in fruit juice products pose a significant risk to human health.

Postharvest pear fruits are susceptible to fungal decay and patulin (PAT) contamination during storage and transportation. PAT is a harmful mycotoxin contaminant of fruits and fruit products. Our team has identified a strain of Hannaella sinensis through preliminary research and validated its ability to degrade PAT in vitro. However, whether H. sinensis can effectively combat postharvest diseases of pears and control PAT within the fruit was yet unknown.

Physiologically based pharmacokinetic (PBPK) models were utilized to investigate potential interactions between aflatoxin B1 (AFB1) and efavirenz (EFV), a non-nucleoside reverse transcriptase inhibitor drug and inducer of several CYP enzymes, including CYP3A4. PBPK simulations were conducted in a North European Caucasian and Black South African population, considering different dosing scenarios. The simulations predicted the impact of EFV on AFB1 metabolism via CYP3A4 and CYP1A2.
