Chefs' recipes and a quest for novelty may be behind a rise in the number of people in the UK eating freshwater fish, but, according to a new report, they may be putting their health at risk. Scientists found that fish such as perch and roach caught in unmanaged inland waterways, including canals, may contain significant levels of toxic chemicals, The Independent reports.
"There is growing evidence that more people in the UK
are consuming fish taken from inland waterways. This may be partly due to the
increased numbers of migrants from Eastern Europe where this is part of
traditional culture, and partly because of a desire to try new foods encouraged
by celebrity chefs," say researchers from the Food Standards Agency and
the Food and Environment Research Agency, whose study will appear in the coming
March issue of the journal Chemosphere.
"This is the first study of a comprehensive set of
contaminants in freshwater fish, and as such is unique. Some samples greatly
exceeded limits [for chemicals] that apply to fish on retail sale for human
consumption. On this basis, it appears that regular consumption of coarse fish
from unmanaged waterways, especially those in areas with an industrial history,
could pose a higher risk to health."
Chefs Gordon Ramsay and Hugh Fearnley-Whittingstall have
endorsed the benefits of freshwater fish as a sustainable alternative to more
endangered ocean species such as cod. Fearnley-Whittingstall's programme Escape
to River Cottage showed the chef preparing jellied pike, while the freshwater
species often appears on the menu at Ramsay's restaurants. This has aided in
elevating the popularity of a fish that, while generally safe to eat when
sourced by a restaurant, can contain potentially damaging levels of chemicals
in the wild.
Inland waterways, especially those close to industrial
areas, are known to be prone to levels of historic or localised pollution which
can, in turn, lead to contamination of fish. But freshwater fish are not part
of the traditional UK diet and are not subject to contaminants regulations that
protect consumer health.
The researchers say some anglers are known to consume their
catch, as are migrant workers from Eastern Europe where consumption of river
fish is a cultural norm, and others keen to explore consumption of new or wild
foods.
Carp is a staple of the Polish, German and Czech Christmas
dinner and it is believed there is a significant rise in the number caught in
Britain around the festive period, leading to increased concerns about the
safety of consumption.
Mike Berthet, director of fish and seafood at M&J
Seafood, voiced his concerns at the growing tendency of angling for personal
consumption.
"The inland water in the UK is notoriously polluted," he
said.
"Anyone not buying fish from registered companies or markets with
requisite quality control is always going to be at risk."
Researchers collected fish from 23 sites around the UK and
tested for a wide range of contaminants. Anglers were also interviewed.
Potentially harmful chemicals found included polychlorinated biphenyls (PCBs),
man-made organic chemicals whose manufacture in the UK was banned more than 30
years ago, and polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated
dibenzofurans (PCDF), both industrial by-products and environmental
contaminants.
