I’m not sure I follow.

The eu regulations no longer apply to food companies operating in the UK, as the UK no longer is in eu-jurisdiction.

The uk govt would have to re-implement them one by one, which a) would be a considerable effort and b) defeats the point of brexit, and thus likely come at political costs.

/edit: thanks for the responses, TIL.

It's the opposite: Upon leaving the EU, the UK basically declared their standards to be exactly those of the EU (at the time that they left), unless the government decides otherwise (there's a bit of a fight about exactly how that happens, as I think at the moment the cabinet has the power to throw out whatever EU legislation they like, as opposed to parliament voting on each repeal, but I might be wrong about whether that actually passed).

This is better than the alternative, which would basically not having any national standards until they developed their own, but you are right that it basically means brexit has mostly increased the amount of paperwork and friction in trading but not actually produced material benefits for most industries in the UK. And in general it makes sense to follow the EU for most standards anyway: if you diverge too much you risk people just not bothering to sell in your country anyway. There's already stupid headaches like this: for EMC certification, if you need a lab to do some tests to sell in the UK and the EU, you currently need to get a lab in the UK and a lab in the EU to perform the exact same tests to the exact same standards. This means a lot of EU companies are just not bothering to certify their products for the UK market (customers will often just import them illegally).

You have it backwards. They have to de-implement them in order to get rid of them. The EU doesn't have federal laws in the way that the US does, each law is independently implemented in each member state.
