Background: Aflatoxins (AFs) are a group of toxic, nephrotoxic, hepatotoxic and carcinogenic fungal metabolites. Heat- and acid-treated yeasts, probiotic bacteria and their combination were used to remove AFB1, AFB2, AFG1 and AFG2 from human and animal food.
Results: The in vitro study revealed that the highest removal percentage of AFs in phosphate-buffered saline was recorded after 72 h with the yeast-probiotic coctile, reaching 95.59%. Therefore, this coctile was added to Cerelac contaminated with AFB1, AFB2, AFG1 and AFG2, and the removal percentages were 8.17%, 36.12%, 44.75%, 64.72% and 93.21% after 6, 12, 24, 48 and 72 h of treatment, respectively. Cerelac yeast-probiotic coctile was administered to female rats and the results showed that all AFs (AFB1, AFB2, AFG1 and AFG2) were detected in the serum of mother rats for both AF groups III and IV. On the other hand, AFM1 and AFM2 metabolites were not observed in mothers' sera but were detected in all infants of groups III and IV. Meanwhile, AFB1, AFB2, AFG1 and AFG2 were not observed in infants' sera.
Conclusion: A mixture of yeast-probiotic coctile was successful in reducing the level of AF in rat sera and diminished the deleterious effect of AFs on animal health. © 2017 Society of Chemical Industry.

Aflatoxins in food and feed with prominent toxic effects have jeopardized public health for decades. This investigation intends to explore synthesized SDS-modified chitosan as new generation of binder for removal of aflatoxin using a straightforward ionic cross-linking approach. The primary objective of this technique was to enhance affinity and adsorption capability of SDSCS towards aflatoxins.

Background: The 11+Myco MS-PREP® Immunoaffinity Column (IAC) contains a gel suspension of monoclonal antibodies specific to the toxins of interest. Following sample extraction, the IAC is used for cleanup and concentration of mycotoxins prior to analysis by Liquid Chromatography with Tandem Mass Spectrometry (LC-MS/MS).
Objective: This study evaluated the IAC with LC-MS/MS method for Performance Tested Methods SM certification for simultaneous determination and confirmation of Aflatoxins B1, B2, G1, G2, and M1; Deoxynivalenol, Fumonisins B1, B2, and B3; Ochratoxin A; T-2; HT-2; and Zearalenone from corn, wheat, cereal-based baby food (with and without dairy ingredients), paprika, chili powder and animal feed.

A magnetic nanoadsorbent was prepared via a novel one-pot magnetization method by employing natural carboxymethyl cellulose (CMC), polyaniline (PANI) nanotube, and graphene oxide (GO) for the effective adsorption of aflatoxins B1 (AFB1) and B2 (AFB2) from rice samples. This synthesized adsorbent combines the multifunction of CMC, PANI, and GO and shows improved extraction performance. FT-IR, XRD, FE-SEM, VSM, and TGA analyses were used to investigate the successful synthesis of the nanocomposite.

Aflatoxin constitutes a significant concern for food and feed safety, posing detrimental health risks to both animals and humans. This study aimed to examine the prevalence and concentration of aflatoxins in maize feed, total mixed ration, and wheat bran collected from specialized dairy farms and local markets in three major urban centers in eastern Ethiopia. A total of 180 feed samples were collected from September 2021 to January 2022 in Chiro town, Dire Dawa city, and Harar city.

Ginger, a fresh rhizome, an economically important spice with extensive nutraceutical activities finds itself in vegetable and therapeutic market. Aflatoxins (AFB, AFB, AFG and AFG) along with ochratoxin A (OTA) are the most significant and the most toxic form of mycotoxins which are produced by various fungi. This study was initiated to assess the contamination of AFs and OTA in raw and dried ginger products, collected from different agro-climatic zones in Punjab, Pakistan employing the high performance liquid chromatography.
