And while users consume the videos TikTok has also become a platform to buy and sell a bite of the action.
After her daughter's death, new safety rules, known as "Natasha's Law", were introduced which require full ingredient and allergen labelling on all food made on premises and pre-packed for direct sale.Kate believes TikTok is allowing sellers to "swerve" basic food labelling requirements as the app allows people not to list any ingredients at all and thinks
the platform should penalise those who don't provide the correct information."Since Natasha's Law has come into effect I feel that, in general, allergy labelling has improved, but it's frightening that a huge platform like TikTok does not have adequate measures to ensure that labelling is in place," she said."The thought of someone with a food allergy, or an allergy parent, buying items that they assume are safe, when in fact they may not be, is really scary."
Mr Williams from Anaphylaxis UK says the ultimate responsibility lies with the seller but does think TikTok could do more."At the moment it's being used as a platform to sell things that may not be safe. They [TikTok] do need to do more," he said, "There's a lot of people making a lot of money, great side hustle, but they're putting people at risk."
Dr James Cooper, deputy director of food policy at the Food Standards Agency (FSA), which is responsible for food safety in England, Wales and Northern Ireland, said: "Wherever people buy their food, it needs to be safe and what it says it is.
"Food businesses in the UK must be registered with their local authority and follow food law. All food businesses have a legal responsibility to sell safe food and provide allergen information."It was galling for Mr Varvill "because we were turning it around with an improved engine. Just as we were getting close to succeeding we failed. That's a uniquely British characteristic."
Did they follow the traditional path after a mass lay-off and head to the nearest pub? "We had a very large party at my house. Otherwise it would have been pretty awful to have put all that effort into the company and not mark it in some way."His former colleague Kathryn Evans headed up the space effort, the work around hypersonic flight for the Ministry of Defence and opportunities to apply the technology in any other commercial areas.
When did she know the game was up? "It's tricky to say when I knew it was going wrong, I was very hopeful to the end. While there was a lot of uncertainty there was a strong pipeline of opportunities."She remembers the moment the axe fell and she joined 200 colleagues in the HQ's auditorium.
