[The detection of Clostridium botulinum in fecal samples of cattle and swine and in the raw material and animal meal of different animal body rendering plants].
Fecal samples of cattle and swine and samples of raw material and pulverized dehydrated meat taken from three rendering plants were investigated with special enrichment methods on the presence of Clostridium botulinum to get a view about the hygienic risk by the incidence of C. botulinum in rendering plants. Eight-six specimens were examined: 25 fecal specimens each of swine and cattle, 11 of raw material and 25 of pulverized dehydrated meat of three rendering plants. Twelve specimens contained C. botulinum: 7 fecal specimens, 6 of swine and one of cattle, 4 raw material specimens and one of pulverized dehydrated meat. C. botulinum was detected by its toxin production in culture medium. Six times C. botulinum type E, twice C. botulinum type B and one time C. botulinum type C was identified. C. botulinum could not be typed in other cases because the toxin quantities were too small. C. botulinum type E was detected in raw material and pulverized dehydrated meat in one of the three examined rendering plants.
