A Marine Harvest Scotland salmon farm on Loch Duich
Marine Harvest 'concerned' over hydrogen peroxide use
Scottish Environment Agency reports 160 farms using the chemical in Scottish waters.
The world’s largest salmon farmer has expressed “concern” over the use of chemicals to fight disease after a record 20 million litres of hydrogen peroxide were dumped into coastal waters around Scotland, reports The Sunday Times.
More than 160 farms resorted to the chemical in 2015 to tackle parasites such as sea lice, according to the Scottish Environment Protection Agency (Sepa).
Enough hydrogen peroxide was used to fill eight Olympic-size swimming pools, including more than 1 million litres at a site operated by Marine Harvest.
