Aflatoxins (AF) are a group of toxic secondary metabolites mostly produced by strains Aspergillus spp. fungi. There several types aflatoxins (AFB1, AFG1, AFB2, AFG2, AFM1, AFM2, etc.), but the most and common is AFB1. have been shown to possess powerful carcinogenic, mutagenic teratogenic properties. AFB1 can contaminate feed food during growth and/or storage under inappropriate conditions. Whe...

A hundred and fifty samples of fish rations were collected and subjected to mycological examination. The total prevalence of Aspergillus flavus was 66.67%. Fifteen isolates among them were aflatoxinB1 producers. AFB1 was extracted and tested for pathogencity. AFB1 intoxicated fish showed off feed, sluggish swimming, dark skin, loss of reflexes, increased mucus secretion, loss of scales and asci...

OBJECTIVE This experiment investigated the effects of aflatoxin B1 (AFB1) alone or mixed with ochratoxin A (OTA) and/or zearalenone (ZEA) on the metabolism, immune function, and antioxidant status of dairy goats. METHODS Fifty lactating Laoshan dairy goats were randomly assigned to one of five treatment groups (n = 10) for 14 days. Goats were fed no additive (control) or administered with 50 ...

OBJECTIVE A 14-d trial was conducted to determine the effects of feeding corn naturally contaminated with aflatoxin B1 (AFB1) on growth performance, apparent ileal digestibility, serum hormones levels and gene expression of Na+, K+-ATPase in ducklings. METHODS A total of 704 ducklings were blocked on the basis of sex and body weight (BW), and then allocated randomly to one of the following tw...

A total of 1,280 1-d-old ducks were used in a study to investigate the effects of increasing aflatoxin B1 (AFB1) concentrations from naturally contaminated corn on young ducklings, and the effectiveness of a clay adsorbent (CA) to protect against those effects. Ducks were randomly allotted to 8 treatments (TRT) in a 4 × 2 factorial arrangement with 4 levels of AFB1 (0, 25, 50, and 100 μg/kg) an...

Aflatoxin B1 (AFB1) is a highly toxic compound (LD50 = 1-50 mg/kg) for most animal species, although it is extremely toxic (LD50 < 1 mg/kg) for some highly susceptible species such as pigs, dogs, cats, rainbow trouts, and ducklings. The toxic effects of AFB1 are both dose and time dependent and two distinct forms of aflatoxicosis, namely acute and chronic, can be distinguished depending on the ...

Aflatoxin is one of the most important topics of research in food contamination . Aflatoxin, a member of the Mycotoxin family, is a secondary metabolite of molds such as Aspergillus Flavus and Aspergillus Parasiticus . These fungi also pollute the crops during production and storage . In the case of the products’ contamination with spores in the desired temperature and humidity conditions, the ...
