Be careful, the disease comes in from the mouth (air-dried beef)

Be careful, the disease comes in from the mouth (part 2 - beef tapeworm)

My son wanted to eat beef jerky, and I remember that a certain Meiju beef jerky was quite famous, so I braved the heavy snow, came to the supermarket, and found the bagged air-dried beef.

Through the plastic bag, I saw the shiny, rosy meat, the four characters of "air-dried beef" on the bag were particularly conspicuous, and then a past event floated in front of my eyes.

At that time, I was still studying at school, there was a class called "Parasitology", the teacher's surname was Zhang, funny and humorous, and his voice was loud, and I can still remember his demeanor.

When it comes to the section on beef tapeworms, we go to the laboratory to observe the entities. In a large glass bottle, beef tapeworms floated in formalin like flat powder bands, filling the entire bottle, teacher Zhang said it was six meters long.

Then, Teacher Zhang asked us to guess, where did the tapeworm come from?

Of course, we couldn't guess, he said the mystery: it was actually from the body of one of our students.

The sister is from Tibet, and every time she returns to school at the end of the holiday, she will give the teacher some hometown specialty - air-dried beef. It was the 1970s, and living conditions were harsh, and the teacher never accepted her air-dried beef. Just after seeing things, asking her how she made it, she said, that is, the fresh beef is cut and dried, resistant to storage, and adults will take a few roads to fill their hunger when they go to graze.

Teacher Zhang was very worried at that time, telling her that the eggs of beef tapeworms are very small, it is difficult to find without careful looking, and the eggs cannot be killed after air drying, and this way of eating has the risk of infecting tapeworms. Asked about her, she said: "I am very healthy, not sick at all. The teacher then asked if she had found a white knot when she was urinating, and she was a little shy, saying that she had never paid attention.

However, the next day, the student sister took the initiative to find Teacher Zhang and said that she did find something white in the feces! The teacher asked her to quickly take samples and send them to the laboratory of the attached hospital, and she was sadly diagnosed with the intestinal beef tapeworm.

So the specimens in our school lab were added to the new member, the big bottle of beef tapeworm.

I think the bigger gain is that when xuejie returns to the Qinghai-Tibet Plateau after graduation, she will definitely publicize and educate the villagers to prevent beef tapeworms, that is, resolutely do not eat raw beef!

Okay, my mind retracted, and with this bag of air-dried beef in hand, I asked the clerk, "How is beef made?" Is there a process of high temperature treatment? Is there a possibility of parasites? ”

The clerk didn't think I was incredible, but told me in great detail: "The beef is first air-dried, then thinly sliced, and then fried, and what parasitic meat is also blown up!" ”

Well, I paid for it with a bag of air-dried beef.

Dear friends, I believe that it is easy for everyone to do it without eating raw beef, and it is easy to understand the principle of separating raw and cooked in the kitchen!
