Growing consumption of beer in present diet may lead to higher risk of piling up of ochratoxin A. In our studies we evaluated malt and beer from the local Pomeranian brewery which offers its products at the market in the lowest price. The evaluation had been conducted for 3 months during winter time and the content of fungi, OTA and ergosterol had been analyzed.High concentration of ergosterol was found in all the malt samples, whereas ochratoxin A was present in one delivery of the product only. In contrast, in 70% beer samples low concentration of OTA was found.

In 1997, large areas in South Poland were affected by a flood of the River Oder. As a immediate measure to support shelterless people living in these areas, simple pavillons were built, which two years later had to be evacuated because of high contamination with moulds. The rate of mould contamination on the walls in interior microclimate and the occurrence of OTA was estimated in two of these pavillions. The air-flow and the moisture were regulated in the experimental rooms where wallpaper was used as the research material. The gypsum cardboards on the walls were also observed. It was found that the moulds were of different species and the number of them was constantly changing irrespective of the accepted configuration of the research position. In every single wallpaper sample OTA was detected. The greatest amount of OTA was found in the pavillions with humidified air. The test of gipsum cardboard walls in pavilions chosen at random, showed an enormous amount of moulds. However, the OTA was not detected.

The effect of high and low doses of ochratoxin A in feed on growing chicken.

Effects of high and low dose of ochratoxin A (OTA) as pure toxin supplemented to feed were investigated on the performance of growing chicken. Two groups were fed with different doses of chemical pure OTA 0.5 ppm and 5 ppm in feed and the effects of toxin on body and organ weights were studied and compared with control group. No effects were observed by feeding 0.5 ppm OTA, whereas 5 ppm had a negative effect on the daily body mass gain. OTA in feed had a negative effect on the daily body mass gain. In contrary nephrotoxic effects could be observed by feeding the naturally OTA contaminated feed with only 0.2 ppm of OTA produced byPenicillium verrucosum.
