In London people swear to God
their “fish and chips” is made from cod
or haddock – but the experts say
they often find the DNA
of dog sharks from the USA,
striped dolphins caught in fishing nets,
fat carp that started off as pets,
Icelandic wartfish, sewer hake,
or Uruguayan water snake –
and vinegar cannot conceal
that underhanded Tory deal
which let in Bangkok gutter eel.
