Contamination of feed with zearalenone (ZEA) is still a serious problem in farm animals feeding, especially in gilts, sensitive to this compound. The relative failure of current methods of decontamination and quality control lead us to look for new techniques. The commonly accepted method for breaking down ZEA was performed in controlled temperature and time conditions. Various sodium carbonate doses (0.5 – 4%) were added to feed naturally contaminated with ZEA (ZEA biosynthesis by F. graminearum isolates). These doses were found to be effective in in vitro studies. The addition of 2% sodium carbonate gave the best results in reducing the phytoestrogen in the feed.

Deoxynivalenol is one of mycotoxins that are most frequently determined in animal feed manufactured in Poland. The examination of histopathological lesions concomitant with deoxynivalenol intoxication is difficult because of the common, often synergistic, reaction of this mycotoxin with other toxins, such as zearalenone or ochratoxin A, which has a strong nephrotoxic activity. The possibility of estimating histopathological lesions in the course of intoxication with pure toxin at various doses is therefore of interest. Dosages used in this experiment relate to clinical cases observed in feeding the animals with whole ration feed obtained by processing feedingstuffs contaminated with Fusarium moulds. However, concerning the fact of one-shot administration of clinically pure toxin, the main question was if it was a sufficient dose to cause changes in the histopathological picture of gastrointestinal tract organs. The experiment was carried out on 12 nursery pigs of mixed breed (Polish White Large x Polish White Ear-pendent) with an average body weigh of 35 kg. The experimental nursery pigs were divided into 3 groups: group I (n=4) – control; group II (n=4) – DON administered at a dose of 0.2 mg/kg b.w.; group III (n=4) – DON administered at a dose of 0.4 mg/kg b.w. After slaughter of the animals, macroscopic examination was performed and segments of duodenum, jejunum, ileum, liver and mesenteric lymph nodes were sampled and assigned for histopathological examination. The results obtained equate to the clinically observed signs in swine production involving some nutrient metabolism disturbances in the gastrointestinal tract in the course of deoxynivalenol mycotoxicosis. Histopathological examination of segments of the duodenum, the jejunum, the ileum, the liver and the lymph nodes indicate that the regressive lesions are more expressed in the experimental group treated with the highest concentration of deoxynivalenol.

The effects of aflatoxin B₁ (AFB₁), ochratoxin A (OTA), patulin (PAT), citrinin (CIT), and zearalenone (ZEA) on in vitro response of pig peripheral blood mononuclear cells to mitogen concanavalin A was assayed after three days of incubation using ³H- thymidine uptake. Dose response curves for each mycotoxin were generated and the concentrations producing 50% inhibition of cell proliferation (IC₅₀) were estimated. AFB₁, OTA, and PAT were the most potent toxins with the IC₅₀ of 0.06, 0.17, and 0.19 µmol/L, respectively (0.2, 0.7, and 0.3 µg/mL, respectively). Based on the molar concentration, the inhibition potencies relative to that of AFB₁ were determined. OTA had 35% and PAT 31% potency to that of AFB₁, but CIT and ZEA had only 1.6 and 1.9 of AFB₁ inhibition potencies.

Ochratoxin A (OA), zearalenone (ZON), moniliformin (MON) as well as trichotecenes and fumonisines (FUM) are naturally occurring contaminants of cereals and animal feed. They pose a health risk not only to humans but also to livestock and, as a consequence, may cause economical losses either due to unfavorable effects on domestic animals themselves or to an increased potential for health effects in human beings consuming mycotoxin-contaminated edible animal products. At present, large-scale studies are carried out in EU countries to determine a safe, admissible concentration of these toxins in cereals and their processed products. The aim of this review is to collect and summarize information concerning the properties, occurrence and toxicity of these mycotoxins.

To contribute towards the knowledge of microbiology of feeds, more than 100 samples of poultry feed mixtures from Slovakia were mycologically investigated in terms of the overall fungal diversity and toxicological potential of isolated fungi. The study revealed that out of 22 genera recovered, Penicillium was the most frequent and diverse genus, followed by Aspergillus and Mucor being found in 89% (34 spp.), 69% (11 spp.) and 50% (4 spp.), respectively. The most frequently encountered taxa were Fusarium proliferatum, followed by Penicillium aurantiogriseum, Mucor racemosus, Penicillium crustosum and Aspergillus flavus. In addition, the following genera were recorded (in descending order) Rhizopus (44%, 3 spp.), Eurotium (42%, 5 spp.), Fusarium (42%, 3 spp.), Cladosporium (31%, 1 sp.), Alternaria (22%, 3 spp.), Absidia (16%, 3 spp.), Acremonium (12%, 2 spp.), Scopulariopsis (10%, 2 spp.), Paecilomyces (4%, 1 sp.), Ulocladium (3%, 1 sp.), Trichoderma (2%, 1 sp.), Zygorrhynchus (2%, 1 sp.), and finally Emericella, Epicoccum, Geosmithia, Monascus, Stachybotrys, Syncephalastrum and Wardomyces, all were encountered in 1% of the samples being represented by a single species. The mean value counts of total fungi ranged from 1 x 103 to 200 x 105 cfu/g. Outcomes from mycotoxin screening within the appropriate potentially toxinogenic species showed a number of mycotoxin producers, namely those forming aflatoxin B1 (n=3), citrinin (17), cyclopiazonic acid (76), fumonisin B1 (86), griseofulvin (42), moniliformin (18), ochratoxin A (5), patulin (56), penitrem A (30) and sterigmatocystin (10).

Przedmiotem badań były trzy, dominujące w zbiorowisku gatunki traw: Dactylis glomerata L., Arrhenatherum elatius P.P. i Alopecurus pratensis L. W czerwcu 2008 roku pobrano pędy generatywne tych traw, rosnące w trzech odległościach od szosy (5, 55, 105 m). Próby na każdej odległości pobrano z 10 losowo wybranych miejsc. Materiałem do badań były całe pędy generatywne oraz poszczególne organy tych pędów (liście, łodyga, kwiatostan). Zebrane próby podzielono na dwie części. Jedną część stanowiły całe pędy generatywne, drugą rozdzielono na poszczególne organy. W przygotowanym materiale roślinnym oznaczono ołów metodą ASA. Rozmieszczenie ołowiu w poszczególnych częściach rośliny było zróżnicowane. Najwięcej tego pierwiastka oznaczono w kwiatostanach, a najmniej w liściach. Przeprowadzone badania wykazały również, że badane gatunki traw mają różną zdolność kumulacji ołowiu w częściach nadziemnych. Najwięcej tego pierwiastka (1,88-6,11 mg∙kg-1 s.m.) na każdej odległości od drogi oznaczono w gatunku Arrhenatherum elatius. Ponadto, średnia koncentracja ołowiu w kilogramie suchej masy tego gatunku była o 1,71 mg wyższa niż w Dactylis glomerata i o 2,12 mg wyższa niż w Alopecurus pratensis. Stwierdzono również wyraźną zależność między zawartością ołowiu w roślinach a odległością od jezdni. W miarę wzrostu odległości zawartość tego metalu istotnie malała.
