Mycotoxins originate from fungal contamination of barley (and other cereals) and can be found at low levels in beer. Filtration is an effective way to remove mycotoxins. This work – at a laboratory scale – assesses the effectiveness of a commercial filter aid in the removal of mycotoxins in beer. Kieselguhr (Celite 577) and rice hull ash (Pattern II type), an emerging alternative filter aid to DE, were evaluated for the removal of ochratoxin A during beer filtration.

The main safety issue of cereal grains is mycotoxin contamination. There is no published information about mycotoxin contamination of organic wheat in the United States. This study quantified the contents of deoxynivalenol (DON) and ochratoxin A (OTA), two frequently occurring mycotoxins, in organic wheat samples collected from six counties in North Carolina by enzyme‐linked immunosorbent assay (ELISA) and high‐performance liquid chromatography (HPLC).

In this study, the antibacterial properties of Pimpinella anisum essential oil (PAO) were evaluated against six food‐related bacteria. Afterward, the effects of different concentrations of PAO on microbial, chemical, and organoleptic properties of minced beef were evaluated during refrigerated storage.

This research was done on the assumption that the risk for hepatocellular carcinoma (HCC) development that attributed to the consumption of highly contaminated food (HCF) with aflatoxin, may have a major contribution to the total of expected risk. If this hypothesis is true, it is easy to apply an effective and low‐cost intervention approach by excluding HCF and then subjecting it to treatments before use.

Fungal contamination of food and animal feed, especially by mycotoxigenic fungi, is not only a global food quality concern for food manufacturers, but it also poses serious health concerns because of the production of a variety of mycotoxins, some of which present considerable food safety challenges.

Fungal mycotoxins are important contaminants of agricultural commodities that pose serious concerns to producers, consumers and exporters. Aflatoxin is a carcinogenic metabolite produced by the fungi Aspergillus flavus and A. parasiticus. These fungi and other mould species living in the soil contaminate several crops including maize.

Background This study evaluated the degradation of pyrrolizidine alkaloids (PAs) from eastern groundsel (Senecio vernalis) in grass silage prepared with different inoculants. Silages were produced from ryegrass with 230 g kg−1 dry matter (DM) content and mixed with eastern groundsel (9:1; w/w fresh matter basis) containing 5.5 g kg−1 DM PA.

BACKGROUND Maize is one of the most important cereals. It is used for different purposes and in different industries worldwide. This cereal is prone to contamination with mycotoxins, such as zearalenone (ZEN), which is produced mainly by Fusarium graminearum, F. culmorum and F. equiseti. Toxin production under highly moist conditions (aw > 0.95) is exacerbated if there are alternations between low temperatures (12–14 °C) and high temperatures (25–28 °C).

BACKGROUND Aspergillus flavus is a major pollutant in moldy peanuts, and it has a large influence on the taste of food. The secondary metabolites of Aspergillus flavus, including aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2), are highly toxic and can expose humans to high risk. The total mold count (TMC) is an important index to determine the contamination degree and hygiene quality of peanut.

The Czech Republic occupies the first place in the world in the frequency of renal and other urinary tract tumours, but their aetiology is unknown. To explore whether carcinogenic and nephrotoxic mycotoxins may contribute to kidney diseases in the Czech population, biomarkers of ochratoxin A (OTA) and citrinin (CIT) exposure were determined in biological specimens from a cohort of 50 patients with malignant renal tumours.

The effect of dietary aflatoxin B1 (AFB1) and Salmonella Enteritidis infection on intestinal permeability was investigated.

Mycotoxins are difficult to monitor continuously, and a tool to assess the risk would help to judge if there is a particular risk due to the inclusion of certain feed ingredients. For this, the toxin contents of 97 commercial fish feeds have been estimated, and the most prominent toxins in fish feed are calculated to be deoxynivalenol, zearalenone, fumonisins and enniatins.
