It was a leaked bioweapon that got out of control
It wasn't. This thing has existed throughout human existence. What we call the plague was virus that jumped from gerbils to humans. It's a rare mistake, but it happens. In the hunter-gatherer days, it meant that the tribe would get wiped out. It also meant the end to the disease. The Black Death didn't died out because the movement and constant influx of people in the cities. 1918 influenza pandemic "was an unusually deadly influenza pandemic, the first of the two pandemics involving H1N1 influenza virus, with the second being the swine flu in 2009.[1] It infected 500 million people around the world,[2] or about 27% of the then world population of between 1.8 and 1.9 billion, including people on remote Pacific islands and in the Arctic."
In our global world, these things don't just spread even faster, they are more likely to happen because of more people. More human-animal interaction.
It has nothing to do with unsanitary conditions. Unsanitary conditions have other issues. America has to chlorinate chickens because of unsanitary conditions, for example. It's result of lack of rules and regulations:
Channel 4’s ‘Dispatches’ exposes danger of cross-contamination with deadly bacteria – because of poor standards outlawed by EU membership
The expose by the Dispatches programme – ahead of exploratory trade talks between Theresa May and Donald Trump on his state visit – uncovered:
* Piles of chicken left on conveyor belts for long periods of time, at the risk of cross contamination.
* Boxes of chicken stacked on top of each other – which could also cause cross-contamination.
* Workers touching raw chicken with bare hands – while one cleared drains with gloved hands, merely washing the gloves before going back to touching raw chicken.
* Drains blocked with chicken – while pieces of and innards lay on the floor and water leaked from machinery.
* Flooded and broken floors where “bacteria could breed”, an EU meat safety expert warned.
* A worker having three fingers amputated, after being asked to operate a machine they had not been trained to use.
Ron Spellman, the assistant secretary general of the European Food and Meat Inspectors Association, said the programme exposed “much lower standards than we’ve got in Britain and in the EU”.
Asked if they were acceptable for British shoppers, he said: “Definitely not, no. This would be a really, really big step backwards for us.”
On the accumulation of meat on conveyor belts, Mr Spellman said: “Some of that poultry will be carrying campylobacter without a doubt, and some salmonella. The more contact they have with other bits of meat, the more contamination will spread.”
And he added: “This practice of stacking the boxes up like that, with the bottom of the box on the chicken that’s underneath, makes it appear to be a comparatively innocent and harmless practice. It isn’t. It’s dangerous.”
She said: “On several occasions, I saw supervisors touching chicken with bare hands. The hygiene in the plant, it was just really kind of a shocker.”
