Intact eggs that have been hard-boiled should be free ofīacteria or spores. Of toxin detected in the recovered egg yolk suggested that bacterial growth wasĬoncentrated in that portion of the egg. This is the first reported case of botulism related to eating pickled eggs. Most foodborneīotulism cases that occur in the United States are the result of improperly home-cannedįoods. botulinum spores include absence of oxygen (anaerobic conditions), lowĪcidity (pH >4.6), temperatures >39 F ), and high moisture content. Spores or inhibit their germination and growth. Median of 23 cases (range: 17-42 cases) of foodborne botulism was reported each year withĪ median of one death (range: 0-2 deaths).Ĭ. In 1997, an annual survey of state epidemiologistsĪnd directors of state public health laboratories identified 24 cases of foodborneīotulism with one associated death (CDC, unpublished data, 1998).

Beets from the original commercial containers were Original commercial container contained no detectable toxin, and bacterial cultures of the The concentration of preformed type B toxin was 1000 times greater in theĮgg yolks than in the pickling liquid and was undetected in the beets.
botulinum was cultured from the pickling liquid, beets,Īnd egg yolk. In samples of the pickled egg mixture at CDC's National Botulism SurveillanceĪnd Reference Laboratory. Room temperature and occasionally was exposed to sunlight.Ĭultures revealed Clostridium botulinum type B, and type B toxin was detected In a glass jar that closed with a metal screw-on lid. The intact hard-boiledĮggs were peeled and punctured with toothpicks then combined with the other ingredients The pickled eggs were prepared using a recipe that consisted of hard-boiledĮggs, commercially prepared beets and hot peppers, and vinegar. The patient recovered after prolonged supportive care. He had prepared 7 days before onset of illness gastrointestinal symptoms beganġ2 hours after ingestion. No exposures to home-canned products however, the patient had eaten pickled eggs A sample of the patient's serum collected before antitoxinĪdministration demonstrated the presence of type B botulinum toxin. Was diagnosed, and a one-vial dose of trivalent (types A, B, and E) antibotulinum toxin
Physical examination confirmed multiple cranial nerveĪbnormalities, including extraocular motor palsy and diffuse flaccid paralysis. During the next 2 days, he developedĭiplopia, dysarthria, and respiratory impairment, necessitating hospitalization and Nauseated, vomited, and complained of abdominal pain. On November 23, 1997, a previously healthy 68-year-old man became Summarizes the case investigation, which implicated home-pickled eggs as the cause.
