Bacillus cereus infection: symptoms, prevention, and risks

Auf einen Blick

  • Bacillus cereus infections, often found in school lunches, fried rice, and leftover rice, can cause vomiting or diarrhea.
  • The bacteria's heat-resistant spores and toxins are not destroyed by normal heating.
  • Prevention involves immediate consumption after cooking, proper refrigeration below 5°C, or keeping warm above 60°C, avoiding the danger zone of 10-50°C for over 2 hours.

仙人掌桿菌感染者,有時會腹痛、水樣腹瀉。示意圖,圖中人物與新聞無關。(圖取自shutterstock)

〔健康頻道/綜合報導〕關心診所小兒遺傳主治醫師梁盛賓在臉書粉專「大花醫師-梁盛賓 激發孩子的生長動能」表示,仙人掌桿菌是食安新聞的常客,特別容易出現在營養午餐、炒飯、隔夜米飯裡。同時提醒,這個菌很難纏,它會產生耐熱芽孢,一般加熱根本殺不死。更危險的是它分泌的毒素,加熱同樣無效。

梁盛賓表示,常見2種中毒症狀,差異甚大。

「嘔吐型」:炒飯、澱粉類是主要來源,吃下去0.5–6小時就開始狂吐,這是「炒飯症候群」。

「腹瀉型」:肉類、濃湯、乳製品為主,潛伏期8–22小時。腹痛、水樣腹瀉、通常1–2天才好。

大多數人不需要抗生素,補水休息即可。但免疫功能差的人、新生兒要特別警覺,嚴重時可引發敗血症、腦膜炎。該怎麼預防仙人掌桿菌感染?要注意煮好立刻吃,如果真的要惜食,記得冷藏在5度以下、保溫在60度以上。避免在10度到50度的的細菌繁殖危險帶,放置超過 2 小時,超過兩天要冷凍。
