2. In vitro degradative effect of purified zearalenone with or without adsorbents after bionic digestion
Abstract The occurrence of zearalenone is considered a major risk factor affecting human and animal health worldwide. Zearalenone-contaminated feed can cause serious disorders and diseases in farm animals. A number of approaches have been developed to counteract zearalenone, but only few can be used. A potential approach to protecting animals against the har

3. Dry fruit as source of fungal contaminants or functional compounds?
Abstract This study evaluated the role of dry fruits as a source of fungal contaminants or functional compounds. Dry apple, apricot, candied fruits, prune, and white and black raisin were evaluated regarding patulin and ergosterol content, centesimal composition, pH, acidity, pectin, and phenolic profile. The ergosterol was detected in 38% of the samples and

4. Mycotoxin contamination of diets for beef cattle finishing in feedlot
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin usi

6. Effects of fed mycotoxin contaminated diets supplemented with spray-dried porcine plasma on cholinergic response and behavior in piglets
Abstract: The aim of this study was to evaluate the effect of spray-dried porcine plasma (SDPP) supplementation on cholinesterase enzymes and its relationship with animal behavior of weaning piglets exposed to mycotoxin contaminated diets. To achieve these objectives, two experimental design approaches were used. Male piglets (7.15±0.61kg) were allocated in

7. Validation and application of an analytical method for the determination of mycotoxins in crackers by UPLC-MS/MS
Abstract An analytical method applying ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was validated for the determination of aflatoxins M2, M1, G2, G1, B2, B1, deoxynivalenol, ochratoxin A, fumonisins B1 and B2, hydrolyzed fumonisins B1 and B2, zearalenone and sterigmatocystin in crackers. The obtained recoveries (70 to 110%) a

9. Leukoencephalomalacia in horses associated with immature corn consumption
RESUMO: A leucoencefalomalácia dos equinos (ELEM) é uma doença causada pela ingestão de micotoxinas (fumonisinas) produzidas por fungos do gênero Fusarium que infectam o milho e/ou seus subprodutos. A doença tem sido descrita pela ingestão de milho maduro com umidade acima de 15% em temperatura ambiente abaixo de 20°C. O objetivo deste trabalho foi

10. Common resistance to Fusarium head blight in Brazilian wheat cultivars
ABSTRACT: Mycotoxin levels in Fusarium head blight (FHB) infections can be difficult to quantify. The relationship between mycotoxin and disease is not consistent and it is not clear if wheatpathogen interaction is of significance in regions where more than one Fusarium species with distinct trichothecene production ability co-exists. This study aimed to inv

11. Control of mycotoxigenic fungi with microcapsules of essential oils encapsulated in chitosan
Abstract Aspergillus and Fusarium are the fungi genera most frequently isolated from cereal grains and other commodities. They are capable of producing mycotoxins, which can affect the human and animal health. Synthetic fungicides have been used to control these fungi, nevertheless, they have acquired resistance and other alternatives are necessary since the

12. Effect of Bacillus spp. on Aspergillus westerdijkiae growth, sporulation and ochratoxin A production in green-coffee medium
Abstract Aspergillus westerdijkiae is one of the most important spoilage and toxigenic fungi contaminating coffee beans and may produce ochratoxin A (OTA), a mycotoxin that characterize a health risk to the coffee consumers. Biological control strategies can be used for prevention of fungal invasion and decrease mycotoxin exposure. The aims of this study wer
