President Magufuli says tests were found to be faulty after goat, sheep and pawpaw[fruit] samples test positive for COVID-19.
Quite an entertaining example of why these COVID19 test kits should be largely dismissed. While these types of examples continually get dismissed as faulty batches, you have to wonder if there are any good batches of test kits out there.
Al Jazeera reports:
They had randomly obtained several non-human samples, including from a pawpaw, a goat and a sheep, but had assigned them human names and ages.
These samples were then submitted to Tanzania’s laboratory to test for the coronavirus, with the lab technicians left deliberately unaware of their origins.
Samples from the pawpaw and the goat tested positive for COVID-19, the president said, adding this meant it was likely that some people were being tested positive when, in fact, they were not infected by the coronavirus.
“There is something happening. I said before we should not accept that every aid is meant to be good for this nation,” Magufuli said, adding the kits should be investigated. 
We cannot confirm where these test kits came from and the authenticity of the president’s claims, but with everything we now know about this ridiculous theatre show it really doesn’t seem too hard to believe.
Be careful what you eat, its not just Bats you need to be concerned about it seems. With goats, sheep and fruit also testing positive, nothing is safe. Assuming you trust the test.
