The current situation is complicated - and is evolving as everyone gets used to Brexit and tries to establish ways around the new complexities. Hopefully before long, this will be resolved. See below for details on the specific couriers.
DHL: As a result of Brexit, phyto-sanitary documentation is needed for all foods to EU recipients. For the moment, DHL has a blanket ban on all foods from UK to all EU countries and this seems to be changing fairly quickly.
DPD: has introduced a new table of prohibited goods and countries. Essentially all goods are prohibited by DPD to all EU countries - for the moment.
