Chef’s stool sample test positive for a toxin in food poisoning cluster case

Chef’s stool sample test positive for a toxin in food poisoning cluster case

2024-04-07

As investigations into a Taipei food poisoning cluster continue, a chef has been found to have traces of the toxin Bongkrekic acid in his stool. Investigators say the toxin may have entered the chef’s body during the cooking process, but the chef did not become ill, and has no traces of the toxin in his blood. Meanwhile, the last person to become ill after eating at the restaurant associated with the cluster is also the first to test negative for the toxin. The female patron said she had symptoms of diarrhea and nausea after eating fried noodles at the restaurant.

In the latest update in a cluster of food poisonings at chain restaurant Polam Kopitiam’s Xinyi branch, Bongkrekic acid was found in a sample of a chef’s stool. Previous samples taken from the hands of the substitute chef, surnamed Hu, also showed traces of the toxin. Investigators on Sunday said Hu is now the key defendant in the case, which resulted in two deaths, and the hospitalization of seven others.

Voice of Victor Wang
Deputy health minister
We were also concerned about the chef’s physical condition, but blood results came back with normal values. We didn’t find Bongkrekic acid in his blood or urine. It’s possible that he consumed it, and the concentration was very low. So it didn’t have an impact on his body, and was subsequently metabolized.

However, environmental tests at the restaurant and at the chef’s home came out negative for any traces of the toxin. Commenting on the situation, one doctor said it could be a rare case where an individual carries a pathogen without being affected by it.

Internal medicine doctor
In such a case, there is a balance between the host’s immune system and the toxin produced by the pathogen, and it does not cause any symptoms to the host. This would not necessarily be the case with the immune systems of others.

The doctor also cited past studies, saying that it is very difficult to completely wash off traces of Bongkrekic acid, and that doing so effectively would require repeated application of complex chemical solutions. Meanwhile, a 39-year-old woman who got sick after eating fried noodles at the restaurant has been added to the list of those affected in the case. The woman developed diarrhea, nausea and general fatigue, but tested negative for traces of Bongkrekic acid. In total, among the 34 people reported in the case, 32 have tested positive for the toxin. Four individuals linked to the case are still in the intensive care unit.

寶林中毒案新進展! 廚師糞便驗出"邦克列酸" 醫:太離奇

2024-04-07

寶林茶室食物中毒案,中央在胡姓代班廚師糞便中也驗出邦克列酸陽性,推測料理過程中接觸到汙染源,但卻不向其他患者出現嚴重肝腎症狀,連醫師驚嘆,胡姓廚師恐怕是邦克列酸的罕見共生體,而昨天食物中毒案也新增一名39歲女子,吃了寶林炒麵而腹瀉噁心,不過她的邦克列酸檢驗是陰性。

寶林中毒案最新進度,在胡姓代班廚師糞便中,再驗出邦克列酸,總計手部和糞便都驗出毒素,但寶林茶室已出現2名死者,而身為關鍵被告身分的這位廚師,健康問題備受關注!

[[聲源:衛福部次長 王必勝]]
“我們也擔心他(代班廚師)的身體狀況,各種生化的數值上,或血液的數值上面都還蠻正常的,那在血液跟尿液上面,也沒有驗出所謂的邦克列酸,他可能有吃到,但是濃度很低,所以沒有對他身體產生影響,那後續已經也代謝掉”

但其他環境採檢包括寶林茶室和廚師家中都沒驗出邦克列酸,讓外界直呼廚師也太幸運,沒有任何中毒現象,還有醫師驚嘆,胡姓廚師恐怕就是邦克列酸的罕見共生體!

[[一般內科醫師 姜冠宇]]
“宿主的免疫力跟病原體它所產生的毒素是達成一個平衡,那其實並不會對宿主,造成任何症狀的發生,別人的免疫力就不一定是這麼一回事了”

醫師也從過去文獻研判,邦克列酸清洗相當困難,甚至要用到複雜化學劑反覆消毒才能夠清除。而寶林案也新增一名39歲女,吃了寶林炒麵,出現腹瀉、噁心和全身倦怠,但採檢她身上邦克列酸呈陰性,總計整起寶林中毒案,通報34人當中,共有32人採檢出陽性,還有4人在加護病房救治。邦克列酸風波持續燒,除了醫治受害者也得找出更多方法防治食物中毒。
