“…Santili (2010) extracted and purified raw milk samples by immunoaffinity columns and quantified aflatoxin M 1 by HPLC-FD, finding it in 49% of the 429 samples collected in São Paulo (SP, Brazil), with 0.7% being above the maximum limit allowed in Brazil. Picinin et al (2013) It is known that aflatoxins are heat treatment stable (Assem et al, 2011;Prandini et al, 2009;Shundo et al, 2009). Studies carried out in Brazil (Scaglioni et al, 2014) and other countries (Farah Nadira et al, 2017;Armorini et al, 2016;Bellio et al, 2016;Zheng et al, 2013;Kabak & Özbey, 2012) prove that even in pasteurized or ultrapasteurized milk, aflatoxin M 1 is found at levels often higher than the allowed maximum limit established by national regulations (Becker-Algeri et al, 2016).…”

The objective of this work was to determine aflatoxin M 1 in fresh milk from fifty-two small farms in the city of Concórdia -SC, Brazil. Samples from the cooling tanks of each property were collected from November 2014 to January 2015. The QuEChERS method was used for the extraction of aflatoxin M 1 , and quantification was performed in UHPLC-FL. 40.4% of the analyzed samples (eg, 21 samples) showed contamination levels by aflatoxin M 1 above the maximum limit allowed by the Brazilian regulation, which is 0.5 μg L -1. These results suggest the importance of implementing Good Practices in obtaining feed for dairy cows, since the contamination of milk by aflatoxin M 1 occurs through the biotransformation of aflatoxin B 1 , after the ingestion of feed or silage contaminated by the animals, posing risk to the animals themselves, as well as to consumers of milk and dairy products. Keywords: aflatoxins; QuEChERS; UHPLC-FL.Practical Application: Contamination by aflatoxin M 1 of the evaluated fresh milk was high.

This study sheds a light on the incidence of aflatoxin M1 and some heavy metals in ninety (90) samples of different types of dairy products marketed in Sharkia governorate including kariesh cheese, white soft cheese and plain yoghurt. The obtained result declared that aflatoxin M1 was highly concentrated in white soft cheese samples followed by kariesh cheese with mean values of 3.56± 0.37 and 2.78± 0.45 μg/Kg, respectively, while plain yoghurt samples recorded the least contamination level with a mean value 0.47± 0.05 μg/Kg. Concerning heavy metal results, The highest residual concentrations of heavy metals were found in kariesh cheese samples with mean values 7.03± 0.15, 0.98± 0.60, 1.67± 0.11 and 0.27± 0.04 ppm for iron, lead, copper and cadmium respectively, while the lowest values were detected in plain yoghurt samples with mean values 1.38± 0.063, 0.54± 0.03, 0.80± 0.05 and 0.18± 0.01 ppm for iron, lead, copper and cadmium respectively. The recorded data of the present study declared that, levels of aflatoxin M1 were higher than those set by Egyptian Standard and European Commission Regulation standards. Also, all the detected heavy metal residues exceeded the maximum permissible limits of the values recommended by international dairy federation standard and the Codex Alimentarius Commission. Finally, the results of our study indicate the importance of continuous and regular monitoring of chemical contaminant levels in different types of dairy products consumed in Sharkia Governorate, as our results show an alarming situation in these products with respect to all dairy product producers.

“…The highest concentrations were found in the coldest seasons, with the highest obtained in autumn. Picinin et al 28 conducted a study in Minas Gerais, Brazil, where concentrations of AFM1 were higher in the dry period (winter) than in the rainy period (summer). All 129 milk samples that were analyzed had AFM1 contamination, with 13.9% showing levels above the legal limit imposed by the European Union.…”

BACKGROUND Aflatoxin M1 (AFM1) is a mycotoxin found in milk as a result of the ingestion of aflatoxin B1 (AFB1) by dairy cattle. Because of its carcinogenic properties, the control of its occurrence in dairy products is of great importance. We evaluated the occurrence and seasonality of AFM1 in milk from farms with subtropical and temperate climates, where significant milk production occurs. Forty samples of raw milk were collected from bulk tansk milk during the summer (five samples from a subtropical climate and 14 from a temperate climate) and winter (six samples from a subtropical climate and 15 from a temperate climate) months of 2017 and conducted an analysis using an enzyme‐linked immunosorbent assay (ELISA) (detection limit 5 ng L−1). Data from eight random samples were compared with respect to liquid chromatography with mass spectrometry detection and ELISA. A significant correlation was observed. RESULTS The presence of AFM1 was detected in 87.50% (n = 35) of the samples analyzed (a mean of 16.66 ng L−1 and a median of 12.42 ng L−1 in positive samples); however, its concentration in all samples was below the maximum limit allowed by European (50 ng L−1) and Brazilian (500 ng L−1) legislations. There were no significant differences in the levels of AFM1 between the properties located in the two climate zones, in both summer and winter. The estimated daily intake of AFM1 based on the milk analyzed was 0.0107 ng kg−1 day−1 for adolescents, 0.0072 ng kg−1 day−1 for adults and 0.0098 ng kg−1 day−1 for the elderly. CONCLUSION The present work demonstrated a low exposure to AFM1. © 2018 Society of Chemical Industry
