Chengdu Customs seized a batch of human saliva samples. Are these samples potentially harmful?

Chengdu Customs seized a batch of human saliva samples. Are these samples potentially harmful? The answer is yes. How to seize it without endangering Chengdu Customs? Just put it down. It was seized because this "human saliva sample" will be potentially harmful, which is beyond doubt.

What are the potential hazards of human saliva samples? The customs believes that "this kind of human saliva sample may contain infectious pathogens such as bacteria and viruses, and there is a risk of the spread of infectious diseases." It is reported that the "human saliva sample" seized this time does not include prior declaration, but is declared in an "immigration document". After opening the box, the customs officers found that there were eight cotton swabs containing human saliva in the package, and the cotton swabs were placed directly in the envelope, which looked very unsanitary.

As we all know, saliva contains a large number of bacteria and viruses, which is a highly dangerous substance that causes the spread of the epidemic. It is for this reason that we have to wear masks when we go out now. Moreover, it is doubtful that this kind of thing was specially mailed from abroad.

Moreover, the "human saliva sample" seized by Chengdu Customs was found in the name of "entry and exit documents", and the express address was a genetic testing company in China. At present, many countries in the world have genetic testing companies. If you want to do genetic testing, you can do it in a country that does express delivery. Why send it to China? Moreover, it is even more incredible to use the "immigration certificate" to declare the name by express delivery. Now no country requires "genetic testing" as a necessary condition for immigration, right? And why is the "immigration document" not a "document" but a "human saliva sample"? This is obviously done on purpose to hide people's eyes and ears. All these signs make it hard not to doubt this "human saliva sample", which further increases the potential harm of this sample, so it is more reasonable for the customs to intercept it.
