Some observations on "paralytic myoglobinuria" of cattle in Britain.

Characteristics of 44 outbreaks of "paralytic myoglobinuria" in yearling cattle reported to veterinary investigation centres during 1974 and 1975 are described. The clinical syndrome and associated nutrition and management of cattle are discussed in the light of present knowledge of this disease with particular reference to the diagnostic and epidemiological value of plasma creatine phosphokinase and blood glutathione peroxidase activities.

Investigation of suspected cases of mycotoxicosis in farm animals in Britain.

Mycotoxins were detected in 13 out of 131 feed samples examined over two years. Screening of feeds associated with cases of suspected mycotoxicosis occurring in farm animals over a further 12 month period showed that most incidents occurred during the winter and involved mainly cattle and pigs fed concentrates. A haemorrhagic syndrome in cattle and abortions in sows were most frequently connected with mouldy food. One or more known toxins (the aflatoxins, ochratoxin A, sterigmatocystin and zearalenone) were detected in three out of 65 cases and a wide variety of fungi were isolated. Toxicity to experimental animals was demonstrated in four out of 22 samples.

Detection of twelve mycotoxins in mixed animal feedstuffs, using a novel membrane cleanup procedure.

A multimycotoxin thin layer chromatographic screening method is described which is applicable to most animal feedstuffs. Interference from nonspecific lipid, pigment, and other components of simple and mixed feeds is reduced to a minimum by using a membrane cleanup step. Aflatoxins B1, B2, G1, and G2, citrinin, diacetoxyscirpenol, ochratoxin A, patulin, penitrem A, sterigmatocystin, T-2 toxin, and zearalenone may be reliably detected. The sensitivity of the method is generally low for mixed feeds but even so aflatoxin B1 can be detected at a level of 3 ppb and ochratoxin A at 80 ppb. While the basic method is less sensitive for sterigmatocystin (330 ppb), patulin (600 ppb), zearalenone (1000 ppb), and the trichothecenes (1000-4000 ppb), it may be adapted so as to reduce the above detection limits when the presence of these toxins is suspected. Lower levels may be detected in extracts of simple feeds.
