Let us be clear about this: A 'wet market' is
> a market selling fresh meat, fish, produce, and other perishable goods as distinguished from "dry markets" which sell durable goods such as fabric and electronics
Fish & Meat counters exist at literally every large supermarket in the UK, is she planning on banning Billingsgate Market? Or, have we just come up with a term 'wet market' - that no one actually has heard before, dressed it up as some asian odity and then decided we need to ban it?
Wet markets aren't a particularly likely place for pandemics to spawn from (let's ignore the fact that there a literally hundreds of thousands of them operating every day). We're not fighting off dozens of epidemics. The thing that enables these outbreaks is bad food hygeine standards, and that doens't improve by banning anything we've decided is vaguely foreign and scary.
