At your request, I'm going to the market to buy some salted herring. I want to examine its microflora under a microscope. I'm also examining the blood of the person who ate the fish under a microscope.
The microflora of the herring itself seemed uniform to me. Many microorganisms were vibrating and enclosed in a kind of sphere. Perhaps these are cysts, where microorganisms hide during unfavorable external conditions? The unfavorable conditions in this case were the salting of the fish.
However, my experience shows that microflora can withstand much higher salt concentrations. And in salted cabbage, for example, the microflora is represented by more lactobacilli. Here, certain microorganisms are apparently more characteristic of a substrate of animal origin.
Or perhaps this is... the normal coexistence of certain microorganisms in a space limited by some kind of shell.
Similar vibrating, more rounded microorganisms were also found without the spheres. Numerous spheres were found in the biomaterial, and in dense areas, these spheres filled the entire space.
Both herring tissue and cells were found, tightly packed together, as is typical for tissue cells.
Overall, the microflora under the microscope was disappointing. One good thing: I didn't find any visible parasites or worms inside the herring.
The person who ate the herring donated blood an hour after the meal, and a large number of microorganisms were found in their blood that shouldn't be there. Human blood plasma should be clean. If foreign microorganisms enter it, the immune system tries to get rid of them. White blood cells are sent to fight the infection, destroying everything in their path. While fighting the enemy, the white blood cells die, forming pus and mucus. If there's a lot of pus, we start blowing our noses and coughing. And now an inflammatory process is evident. When there's an excess of microorganisms in the blood, the immune system produces more white blood cells, which can lead to leukocytosis, or simply an elevated white blood cell count. I remember having a consistently elevated white blood cell count when I ate animal foods (as a child).
I don't know about you, but I'm coming to the conclusion that herring isn't the best food for humans.
