“…Kojic acid (KA) is a secondary fungal metabolite of many species of Aspergillus, Acetobacter, and Penicillium (Burdock, Soni, & Carabin, 2001). In this survey, KA occurred in less than half of the samples (43%) at higher levels than those reported previously in other commodities such as maize (5357 μg/kg) and groundnut (485 μg/kg) from Nigeria (Kayode et al, 2013), maize from Brazil (1719 μg/kg) (Oliveira, Rocha, Sulyok, Krska, & Mallmann, 2017) and maize from Egypt (25040 μg/kg) (Abdallah, Girgin, Baydar, Krska, & Sulyok, 2017). The detection of KA has not been detected in dates or in any other dried fruits before.…”

Mycotoxins are secondary metabolites produced by different fungi. These metabolites pose a potential risk on human health since they contaminate many food commodities. Among these, date palm fruits which are an integral part of diet in several countries. Therefore, detection of mycotoxins is a prerequisite to insure the safety of food. Here, different types of mycotoxins have been detected in levels that may have health hazard.

“…Consequently, Alternaria mycotoxins were detected in cereals and derived products [46,[57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76], feed [74,[109][110][111][112][113], dairy products [114], grapes and by-products [27,77,115], tomatoes and derived products [31,47,77,81,106,113], nuts and by-products [102,116], spices [117], soybeans [76,116,118], sunflower seeds [85,104,107], vegetables [27,101], vegetable oils [105], strawberries …”

Alternaria is one of the major mycotoxigenic fungal genera with more than 70 reported metabolites. Alternaria mycotoxins showed notably toxicity, such as mutagenicity, carcinogenicity, induction of DNA strand break, sphingolipid metabolism disruption, or inhibition of enzymes activity and photophosphorylation. This review reports on the toxicity, stability, metabolism, current analytical methods, and prevalence of Alternaria mycotoxins in food and feed through the most recent published research. Half of the publications were focused on fruits, vegetables, and derived products-mainly tomato and apples-while cereals and cereal byproducts represented 38%. The most studied compounds were alternariol, alternariol methyl ether, tentoxin, and tenuazonic acid, but altenuene, altertoxins (I, II, and III), and macrosporin have been gaining importance in recent years. Solid-liquid extraction (50%) with acetonitrile or ethyl acetate was the most common extraction methodology, followed by QuEChERS and dilutiondirect injection (both 14%). High-and ultraperformance liquid chromatography coupled with tandem mass spectrometry was the predominant determination technique (80%). The highest levels of alternariol and alternariol methyl ether were found in lentils, oilseeds, tomatoes, carrots, juices, wines, and cereals. Tenuazonic acid highest levels were detected in cereals followed by beer, while alternariol, alternariol methyl ether, tenuazonic acid, and tentoxin were found in legumes, nuts, and oilseeds.

Exposure of animals to mycotoxins, through the ingestion of contaminated food, may result in harm to their health as well as that of humans, who are consumers of the products obtained from this raw material (Benkerroum, 2016;Gacem & Hadj-Khelil, 2016;Dliveira et al, 2016;Wilson et al, 2002).…”

Incidence of aflatoxin M1 in fresh milk from small farms

et al. 2017

View full text Add to dashboard Cite

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.
