“…Mycotoxins are mainly produced on small grains, cereals such as wheat, barley, oats, rye and triticale or on corn but animal products such as milk, meat, liver or eggs can also be contaminated by mycotoxins at various points of the feed and food chain (Gacem and El Hadj-Khelil, 2016;Udovicki et al, 2018). Because the sampling of feeds and foods for mycotoxin analysis may follow quite different protocols in different laboratories the standardization of these procedures represents a real challenge for analytics.…”

“…They represent a risk factor to human health directly in the food chain and through biological transformations as well. Mycotoxinogenic fungi are present mainly in small grains like wheat, barley, rye, rice, triticale, and corn (Miller, 2008;Gacem and El Hadj-Khelil, 2016;Udovicki et al, 2018) and also in different feedstuffs. In fact, aflatoxins were first discovered following a severe livestock poisoning incident in England involving turkeys (e.g., Amare and Keller, 2014;Keller, 2019).…”

“…Moreover, some of the antifungal metabolites released by LABs can reduce and inactivate toxins. These metabolites are such as phenolic compounds, Hydroxy fatty acids, Hydrogen peroxide, and Proteinaceous complexes (Gacem & Ould El Hadj-Khelil, 2016;Hashemi, Mousavi Khaneghah, Kontominas, et al, 2017;Salminen et al, 2004).…”

One of the most studied mycotoxins is Aflatoxin M1 (AFM1), which as a carcinogen should be eliminated or limited from food products especially dairy products. Among different detoxification methods of AFM1, several strains of lactic acid bacteria (LABs) (particularly Lactobacillus acidophilus and Bifidobacterium spp.) can bind Aflatoxin M1 and furthermore, eliminate them. The principal mechanism of detoxification by LABs is the physical binding to peptidoglycan and polysaccharides present in the bacterial cell wall. This paper reviews the detoxification capability of some LABs strains and the critical roles of factors affecting the binding procedures including LAB strains, optimum incubation time, and the cell concentration of LABs. Practical application This study reviewed the impact of lactic acid bacteria on detoxification of aflatoxin M1. As the high toxicity effect of aflatoxin M1 in food is proved, finding a safe method in order to remove them is crucial. Lactic acid bacterias (LABs) are vastly applied in food science and technology due to their various beneficial effects, being easy manageable and safe technique. LABs were completely efficient in the elimination of aflatoxins in food besides having no potential adverse health/toxic effects.

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

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.
