the aim of this study was to evaluate aflatoxin m1 (afm1) contamination in pasteurized milk samples in mashhad, iran. one hundred and ten milk samples from different supermarkets were collected during three months in spring and investigated by enzyme linked immuno sorbent assay (elisa). afm1 was found in 100% of the milk samples. about 5.4% of the samples contained afm1 greater than the maximum...

Background: Aflatoxin M1 (AFM1) is a toxic and carcinogenic mycotoxin which after presence in milk and dairy products such as cheese and butter could make them as contaminated food. The main objective of this study was to evaluate the concentration of AFM1 in pasteurized and traditional cheese marketed in Southern Khorasan, from December 2011 to January 2012. Methods: A total of 102 cheese sam...

Mycotoxins are the secondary metabolites of molds and have adverse effects on humans, animals, and crops, resulting in illnesses and economic losses. Aflatoxin M1 (AFM1) is a hepatocarcinogen found in the milk from animals that have consumed feeds contaminated with aflatoxin B1 (AFB1). Milk is a highly nutritious food and is a source of necessary macro- and micro-nutrients for the growth, devel...

aflatoxin m1 (afm1), a carcinogenic substance is found in milk and dairy products. the effect of season and type of dairy products on afmi level in northern iran was investigated in this study.three hundred samples (each season 75 samples) including raw and pasteurized milk, yoghurt, cheese, and cream samples were collected from three distinct milk producing farms. the samples were subjected to...

In this article, we designed and studied silicon oxynitride (SiON) microring-based photonic structures for biosensing applications. We designed waveguides, directional couplers, and racetrack resonators in order to measure refractive index changes smaller than 10-6 refractive index units (RIU). We tested various samples with different SiON refractive indexes as well as the waveguide dimensions ...

Aflatoxins are natural secondary metabolites produced by some moulds (mainly Aspergillus flavus and Aspergillus parasiticus) and are contaminants of agricultural commodities in the field particularly in critical temperature and humidity conditions before or during harvest or because of inappropriate storage (Rustom, 1997; Sweeney & Dobson, 1998). Aflatoxins B1 (AFB1) and B2 (AFB2), producted by...

Dairy milk holds a prominent position as widely consumed food, particularly among infants and children. However, it is crucial to address the presence of multiple natural toxic compounds that may co-occur in dairy ensure its safety prior consumption. Aflatoxin M1 (AFM1), an emerging mycotoxin interest, potential contaminant animals who ingest aflatoxin B1 (AFB1). The toxin regulated European Un...
