Because the pig blood sold in the vegetable market is rarely disinfected or inspected for hygiene and safety. The pig blood sold in our small local vegetable market is actually very dirty. Many pig blood is rich in some dirty things left by killing pigs, so if you want to eat bleeding, you should go to a regular local vegetable market to buy it. It's actually not bad, but it still feels unsanitary. If you can't eat it, try not to.
But in fact, many things we eat in our lives are unsanitary, and we have no way to be careful, or we have a lot of time to investigate these safety and health problems. What we can do is to eat out as little as possible, make our own food as much as possible, or take some measures at home to make the food we eat healthier and more secure, because there are too many things on the market now, which can be said to be hygienic and safe, which is very substandard. Especially in the past two years, there have been news that a restaurant failed to meet the hygiene standards, and then it was fined or even closed down, which made us people feel very scared after listening to it.
Food safety has always been a particularly big problem, but we have to say that even if we know that some things are unsanitary, we will still choose to use them, because we already feel that some things seem to be used to it, because some things are dirty if you don't eat them. If you don't eat them, you can do nothing. How can you not eat them? You can only choose to eat as little as possible.
But in life, it is better to eat less bleeding and blood pressure from other animals, because I think hygiene is really worrying and dirty, especially like internal organs. It is very troublesome to clean up these things in the city, and businesses are often too lazy to clean up. Something with a strong taste, even if it has a little taste, or after adding a strong taste, is often not eaten.
