So here's a news article.
Facebook: Home food businesses concern FSA watchdog www.bbc.co.uk/news/uk-51475289
"BBC News found a wide variety of food for sale by unregistered sellers on Facebook Marketplace. This included cooked meals and baked goods - and in one case, a whole deer."
"The BBC conducted a series of test purchases across the Midlands, buying goat curry, cake, roast chicken and chocolate party cones for children from sellers advertising on Facebook Marketplace. None of the sellers indicated they were registered, had been inspected or had a food hygiene rating."
I know people sometimes advertise cake-making businesses, but apart from that, who is actually buying this stuff? Apart from investigative journalists, I mean.
