1. Determination of aflatoxin M1 in breast milk and related factors
SUMMARY OBJECTIVE: Breastfeeding in women with aflatoxin M1 exposure may be a risk factor for the newborn. Thus, it is crucial to determine aflatoxin M1 levels in breast milk and raise mothers’ awareness about nutrition in lactation and other periods. This study was carried out to determine aflatoxin M1 contamination in milk samples taken from mothers who

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

5. Combining abilities analysis for ear rot resistance in popcorn hybrids development
ABSTRACT Ear rot caused by fungi of genus Fusarium (FER) is one of the potentially harmful diseases to grain quality in maize. Given the capacity to produce mycotoxins, FER presents a risk to food safety. This study sought to identify parents and indicate hybrids of popcorn with a higher level of resistance to the incidence and severity of FER. Hybrids were

6. 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

8. Assessing the implications of mycotoxins on productive efficiency of broilers and growing pigs
ABSTRACT: The effects of mycotoxins on the productive performance of growing pigs and broilers were evaluated using meta-analytical approach. Two databases were constructed: (1) Broilers, with information collected from 51,497 birds and published in 158 scientific papers from 1980 to 2016; and (2) Pigs, with information collected from 7,743 animals and publi

9. Clinical biochemistry profile of American Quarter Horse broodmares fed Tifton-85 (Cynodon spp.) hay and haylage
RESUMO: A conservação do haylage (alimento pré-seco) pode ser desafiadora, considerando o aumento do risco de crescimento de fungos, com consequente produção de micotoxinas. Entretanto, quando a qualidade da higiene e armazenamento é assegurada, o haylage aumenta a palatabilidade da forragem e fornece suplemento de matéria seca suficiente ao longo do

10. 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

12. 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
