In the present study, mycobiota and natural occurrence of aflatoxin B1 (AFB1) in pellet feed and feed ingredients used in a feed manufacturing plant for rainbow trout nutrition was investigated. The samples were cultured on the standard isolation media for 2 weeks at 28 ºC. Identification of fungal isolates was implemented based on the macro- and microscopic morphological criteria. AFB1 was d...

background & aim: aflatoxin (af) is the most important fungus that contaminates food and feed and can enter the food chain of humans. the aim of this study was to investigate the ability of thistle seeds (silybum marianum l.) to reduce the adverse effects of aflatoxin b1 (afb1) on the immune system, variables related to the intestine, appearance and mortality of the broiler chickens. exper...

this experiment was conducted to evaluate the ability of silybum marianum seeds (sms) on performance, carcass variables, and liver morphology of the broiler chickens contaminated with aflatoxin b1 (afb1). a total of 216 broiler chicks (ross 308) were used. birds were randomly assigned to nine treatment groups, with four replicates and six birds in each replicate. chickens were reared on litter ...

The objectives of this study were: 1) to examine effects of a dietary sodium bentonite, ASTRABEN–20 (AB20) [Prince Agri Products, Inc., Quincy, Ill.], on in vitro binding of T2 toxin and aflatoxin B (AFB1); ® 1 and 2) to examine the effects of AB20 in broiler chicks fed 6 ppm dietary T2 toxin (T2) or 4 ppm aflatoxin B1 (AFB1) to 21 d. Day-old male broiler chicks were randomly placed in batterie...

Previous studies conducted in our laboratory have demonstrated that intestinal barrier function can be adversely affected by diet ingredients or feed restriction, resulting in increased intestinal inflammation-associated permeability. Two experiments were conducted in broilers to evaluate the effect of three concentrations of Aflatoxin B1 (AFB1; 2, 1.5, or 1 ppm) on gastrointestinal leakage and...

Crops contaminated with fungal mycotoxins such as aflatoxin B1 (AFB1) are often downgraded or removed from the food chain. This study aimed to evaluate the tolerance and accumulation of AFB1 in two insect species to determine whether they could be used to retain condemned mycotoxin contaminated crops in the food chain. First, instar black soldier fly larvae (Hermetia illucens, BSF) and yellow m...

Two experiments were conducted to screen microorganisms with aflatoxin B1 (AFB1 ) removal potential from soils and to evaluate their ability in reducing the toxic effects of AFB1 in ducklings. In experiment 1, we screened 11 isolates that showed the AFB1 biodegradation ability, and the one exhibited the highest AFB1 removal ability (97%) was characterized and identified as Cellulosimicrobium fu...

Aflatoxin-producing fungi contaminate food and feed during pre-harvest, storage and processing periods. Once consumed, aflatoxins (AFs) accumulate in tissues, causing illnesses in animals and humans. Most human exposure to AF seems to be a result of consumption of contaminated plant and animal products. The policy of blending and dilution of grain containing higher levels of aflatoxins with unc...
