Due to its toxic properties, high stability, and prevalence, the presence of deoxynivalenol (DON) in the food chain is a major threat to food safety and therefore a health risk for both humans and animals. In this study, experiments were carried out with sows and female rats to examine the kinetics of DON after intravenous and oral administration at 100 µg/kg of body weight. After intravenous a...

Mycotoxins are fungal secondary metabolites contaminating food and causing toxicity to animals and humans. Among the various mycotoxins found in crops used for food and feed production, the trichothecene toxin deoxynivalenol (DON or vomitoxin) is one of the most prevalent and hazardous. In addition to native toxins, food also contains a large amount of plant and fungal derivatives of DON, inclu...

Twenty six isolates of Fusarium graminearum from grains of maize hybrids harvested in ±west Argentina were grown on autoclaved rice grain to assess their ability to produce type B trichothecenes. Chemical analysis indicated that 38% of isolates were nivalenol (NIV) producers only, 31% were major NIV producers with high DON(deoxynivalenol)/NIV ratios, 8% were major DON producers with minor NIV p...

To evaluate the fate of deoxynivalenol (DON) in broilers, DON was administered either intravenously or orally to broilers at a dose of 1 mg/kg BW. Concentrations of DON in plasma were measurable up to 4 hr and 2 hr after intravenous and oral administration, respectively. Following intravenous administration, the values for the elimination half-life, the volume of distribution and the clearance ...

Deoxynivalenol (DON, vomitoxin) is a type-B trichothecene mycotoxin produced by several field fungi such as Fusarium graminearum and Fusarium culmorum and known to have various toxic effects. This study investigated the effect of the bread making process on the stability of DON in common bread and wheat germ-enriched bread using naturally contaminated ingredients at the level of 560 µg/kg. The ...

The trichothecene mycotoxin deoxynivalenol (DON), a frequent contaminant of cereal grains, is known to dysregulate mucosal and systemic immunity. In this study, we tested the hypothesis that DON interferes with the murine immune response to viral respiratory infection. Female Balb/c mice (5 weeks old) were orally gavaged with DON (10 mg/kg body weight [bw]) or saline vehicle and then intranasal...

Deoxynivalenol (DON), one of the most abundant trichothecenes found on cereals, has been implicated in mycotoxicoses in both humans and farm animals. Low-dose toxicity is characterized by reduced weight gain, diminished nutritional efficiency, and immunologic effects. The levels and patterns of human food commodity contamination justify that DON consumption constitutes a public health issue. DO...

The experiment was conducted to investigate the effect of different doses of deoxynivalenol on plasma indices of broiler chickens. Forty-two one-day-old male broiler chicks were fed 1 of 3 diets containing deoxynivalenol (DON) for 42 d. The diets included: (1) control (0.2 ppm of deoxynivalenol), (2) low level of deoxynivalenol (1 ppm of DON), and (3) high level of deoxynivalenol (3 ppm of DON)...

Deoxynivalenol (DON) is one of the major mycotoxins produced by Fusarium fungi, and exposure to this mycotoxin requires an assessment of the potential adverse effects, even at low toxin levels. The aim of this study was to investigate the effects of a short-term, low-dose DON exposure on various gut health parameters in pigs. Piglets received a commercial feed or the same feed contaminated with...
