細胞培養污染是指培養環境中侵入了對細胞生存有害的成分和造成細胞變異的異物。體外細胞培養污染可分為三類：物理性、化學性及生物性污染。

物理性污染：
物理性污染通過影響細胞培養體系中的生化成分，從而影響細胞的代謝。
物理性污染的來源：培養環境中的物理因素，如溫度、放射線、振動、輻射（紫外線或熒光）會對細胞產生影響。
物理性污染的現象：細胞、培養液或其他培養試劑暴露在放射線、輻射或過冷過熱的溫度中，可以引起細胞代謝發生改變，如細胞同步化、細胞生長受抑制，甚至細胞死亡。
化學性污染
化學性污染是一些對細胞有毒性的或對細胞產生刺激的化學物質。
化學性污染的來源：
未純化的物質、試劑、水、血清、生長輔助因子及儲存試劑的容器都可能成為化學性污染的來源。細胞培養的必需養分（如氨基酸）若濃度超過了合理的范圍，也會對細胞產生毒性。同樣，不同細胞系在*培養條件下對血清和緩沖液的要求是不一樣的，在培養中應嚴格控制。
化學性污染的現象：化學性污染同樣會使細胞生長受抑制，甚至細胞死亡。
生物污染
生物污染包括比較容易發現的細菌、霉菌和酵母的污染，和較難發現的病毒、支原體和其他細胞的污染。
生物性污染的來源：
 取材不慎或處理不當
 空氣塵埃
 消毒不嚴
 操作不當
 試劑尤其是血清污染
生物性污染的現象：
細菌：G+菌較多。
 真菌：霉菌較多。
 支原體：不易檢測。
 病毒：由于病毒有種屬特異性，所以病毒污染的概率比較小。

But half an hour later, her stomach began to discomfort and went back home to her stomach. After taking a few antidiarrheal drugs, still run the toilet. From more than eight in the evening to six in the second day in the morning, more than fifteen times have been pulled, and the body is extremely tired.

After the hospital diagnosis and the laboratory test, the original Miss Liu was eaten without washing the strawberry caused by acute gastroenteritis.

A tall, delicious strawberry,

Why is the consequences so serious after eating?

Zhou Guozao, the deputy chief physician of Xiamen Pu Pu hospital, introduced the seemingly clean strawberry. Because of the surface protruding particles, there are many tiny concave parts, which are easily attached to dust, bacteria and even pesticide residues. If cleaning is not clean, it may cause diarrhea.

And there's a more important reminder -

Children eat strawberries

May be infected with NOx virus!
Norovirus is a leading cause of acute nonbacterial gastroenteritis virus, also known as Norwalk virus. Norovirus infection may occur throughout the year, but it has the highest incidence in the cold season from November to February, so it is also known as "winter vomiting".

During this period of flu, norovirus is "run amuck".

Norovirus can pass through

The contact between people, food and water intake port communication

The main cause of infective diarrhea is as follows:

Nausea, vomiting, fever, abdominal pain and diarrhea

The incubation period is more than 24~48 hours
