A good question is how did they not recognize that they weren’t looking at human DNA?
Well it is Tanzania. Not sure what equipment they are using or how they do their tests.
We don’t need to use goat milk to set a trap for the fakers here.
All we need to do is take say a thousand people who have tested negative, then send the same samples/people to testing centers we suspect are cooking the books and then wait for what kinds of results we get from them.
Lab techs do not look at the samples through a 'scope. They just add the indicated chemicals into the sample and read the results. There is no real science going on for testing.
