Erkennung von Aflatoxin B₁ in den Geweben des freilebenden Wildes (Lepus europaeus, Phasianus colchicus, Capreolus capreolus, Anas platyrhynchos)

Abstract

Detection of Aflatoxin B1 in the Tissues of Game Animals (Lepus europaeus, Phasianus colchicus, Capreolus capreolus, Anas platyrbynchos)This contribution states concentrations of products of toxogenic mould fungus Aspergillus in livers, kidneys and testes of specific game animals.In hares (Lepus europaeus), there was determined an average concentration in livers of 0.407 pg .kg-1 ? 0.29, in kidneys 0.658 pg . kg-1 ic 0.60, in testes 0.523 pg . kg-1 k 0.27 and in the ovaries 0.207 pg .kg-1 ? 0.19. Higher values were found in those animals with silage pits, hayricks and liquid manure pits nearby.In roe deer (Cupreolus cupreolus), average concentration of Aflatoxin showed the following results: livers -0.696 pg . kg-1 k 0.59, kidneys -0.794 pg . kg-1 f 0.48, testes -0.367 pg . kg-1 f 0.22.The different values found in the organs are likely to be dependent upon the varying resistance of species when digesting, and also upon the wide-spread variance of intaken food. Average concentration of Aflaroxin B1 in pheasants [Phusianus colchicus) were recorded to be in livers 0.329 pg . kg-1 f 0.38, and in kidneys 0.676 pg . kg-1 f 0.59. Controlled contents of mycotoxin in livers of mallards [Anus platyrhyncbos) was found to be 0.840 pg . kg-1, in kidneys 0.594 pg . kg-1 5 0.85.Animals living in ecologically strained localities showed maximum values of 3.605 pg . kg-' in kidneys and 2.484pg . kg-1 in livers.An alimentary and inhalatory path for mycotoxin or for solely mould fungus into the organism could be found in the rearing of chicken. Detection of Aflatoxin B1 was performed by the means of proved radioimmunological screening method (33) that had been accompanied by routine chromatographic methods. EinleitungEiner der zahlreichen Mykotoxikosen, die Erkrankungen bei Menschen, Haw-und freilebenden Tieren hervorrufen, sind Aflatoxikosen. Die toxischen Produkte einiger Schimmelpilze aus der Gattung Aspergillus kontaminieren eine ganze Reihe von Lebensmitteln und Futtermitteln, wobei ein Gesundheitsrisiko entsteht (4, 5, 14, 23, 34).
