Zusammenfassung

Frische Fischprodukte stellen wegen ihrer primären Kontamination mit Sporen von Clostridium botulinum, der häufig verwendeten luftdichten Verpackung, des Verzichts auf Konservierungsstoffe und auf eine Hitzeinaktivierung von bereits gebildetem Botulinum-Toxin und wegen der verminderten Kälteempfindlichkeit des bei ihnen typischerweise vorkommenden C. botulinum Typ E Lebensmittel mit einer ganz besonderen Gefährdung für die Entstehung eines Lebensmittelbotulismus dar. Die Kasuistik schildert einen 25-jährigen Patienten, bei dem 12 h nach dem Verzehr von luftdicht verpacktem Räucherlachs ein Lebensmittelbotulismus mit einem anticholinergen Syndrom mit Mydriasis, Akkomodationsstörungen, Mundtrockenheit, vermindertem Schwitzen, Obstipation sowie verminderte Herzfrequenzvarianz und nur diskrete, Beteiligung der quergestreiften Muskulatur mit Ptosis, Doppelbildern und vorzeitiger generalisierter Ermüdbarkeit auftrat. Der Verzehr des Räucherlachses erfolgte 3 Tage nach Ablauf des Verbrauchsdatums.

Summary

Fresh fish products are exquisitely prone to be the source for food botulism because of primary contamination with Clostridium botulinum spores, lack of heat inactivation of C. botulinum spores, frequently used air-tight packaging, lack of preservatives, lack of heat inactivation of already produced botulinum toxin and because of substantial low temperature resistance of C. botulinum type E typically found in fish botulism. We can reporting a 25-year-old patient with food botulism presenting with an anticholinergic syndrome with mydriasis, accommodation difficulties, dryness of mouth, reduced sweating, constipation and reduced heart rate variance and only discrete involvement of striate muscles with ptosis, diplopia and generalised fatigue, all of which developed 12 h after the consumption of airtight sealed smoked salmon. The salmon was consumed 3 days after the ‘use by’ date had expired.
