So far, only circumstantial evidence has indicated that aflatoxin is involved in the aetiology of liver cancer1, but we have found that it is possible to investigate this relationship by measuring the urinary excretion of aflatoxin M1, which is the hydroxylated product of B1.

Food Additives & Contaminants: Part B, 2014
Tarhana chips are a popular traditional fermented food consumed widely in the Kahramanmaraş region of Turkey. Tarhana chips are different from many other types of fermented food in that they are produced in the form of tortilla chips. Cereal and yoghurt are the main ingredients in Tarhana chips.

Radioimmunoassay of aflatoxin M1
Journal of Radioanalytical and Nuclear Chemistry Letters, 1987Radioimmunoassay for the differential determination of aflatoxin M1 has been developed. It is based on the use of antiserum having almost the same affinity to both aflatoxins B1 and M1 /Ka for aflatoxin B1=2.0×109 and Ka for aflatoxin M1=2.1×109/ and making possible their simultaneous determination.

Association of aflatoxin M1 with casein
Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1982Equilibrium dialysis was used to determine whether aflatoxin M1 (AFM1) binds to casein. Simulated milk ultrafiltrate (SMUF) containing 10 or 20 ng/ml of AFM1 was dialyzed against SMUF containing casein micelles. After 24 h at 7 degrees C, the casein suspension contained 2.5- or 2.9-fold, respectively, more toxin than that found in SMUF.

Aflatoxin M1 in yoghurts in Portugal
International Journal of Food Microbiology, 2004Aflatoxin M1 (AFM1) may occur in milk and milk products, resulting from the ingestion of aflatoxin B1 in feedstuffs by dairy cow. Ninety-six samples of commercial yoghurts (48 natural yoghurts and 48 yoghurt with pieces of strawberries) that are produced in Portugal were analyzed for the presence of AFM1 by immunoaffinity column extraction and high ...

Aflatoxin M1 in milk, in Southern Italy
Mycotoxin Research, 1985A survey on the occurrence of aflatoxin M1 was carried out in the province of Bari (Italy) on a total of 106 samples of raw milk from local farms, commercially heattreated milk, and dried milk. About 72% of the samples were contaminated with aflatoxin M1 within the concentration range 4-280ng/Kg.

Carcinogenicity of synthetic aflatoxin M1 in rats
Food and Cosmetics Toxicology, 1974Abstract Synthetic, racemic aflatoxin M1 administered to male Fischer rats by stomach tube in 40 doses totalling 1 mg/rat induced hepatocellular carcinoma in one rat of a group of 29 killed 100 wk after dosing. Natural aflatoxin B1 at the same dose induced liver tumours in 9 9 rats after 53 wk.

The aflatoxin M1 (AFLAM1) is a mycotoxin that results from the hydroxylation of the aflatoxin B1 (AFLAB1). It contaminates the milk of animals fed with a diet containing its precursor. In this work, we determined the occurrence of AFLAB1 and AFLAM1 in milk, as well as the chromatographic conditions to quantify these mycotoxins.

Prediction of shorter oligonucleotide sequences recognizing aflatoxin M1
Biotechnology and Applied Biochemistry, 2017AbstractAflatoxin M1 (AFM1) is present in milk of lactating animals fed on aflatoxin B1 contaminated feeds. Aptamers are new emerging ligand molecules and can be employed in assay protocols. Shorter aptamers have several advantages. Untruncated (72‐nucleotide long) and truncated (18‐ to 42‐nucleotide long) aptamers were evaluated for AFM1 recognition ...

Chicken CYP1A5 is able to hydroxylate aflatoxin B1 to aflatoxin M1
ToxiconAflatoxin B1 (AFB1), a naturally-occurring mycotoxin, can cause severe toxicological and carcinogenic effects in livestock and humans. Given that the chicken is one of the most important food-producing animals, knowledge regarding AFB1 metabolism and enzymes responsible for AFB1 transformation in the chicken has important implications for chicken ...
