Environmental activists held a protest outside the Moy Park factory in Craigavon, County Armagh on Sunday.

In the protest organized by Slí Eile, a group that describes itself as an anti-capitalist climate action group, demonstrators simulated vomiting in front of the factory.

The group said more than 100 activists took part in the action to raise awareness of “the major role of factory farming in ‘killing Lough Neagh’ and accelerating climate change.”

BBC News NI has contacted Moy Park for comment.

Moy Park supplies branded and own label chicken products to retailers and foodservice operators across the UK, Ireland and Europe.

It was Northern Ireland’s top-selling company last year. Analysis for Ulster Business Magazine suggested.

In June a BBC investigation concluded that the company had violated environmental laws through the way it disposed of its waste.

Documents filed with Stormont’s Department of Environment, Agriculture and Rural Affairs show the company exceeded legal limits hundreds of times at three different sites in Northern Ireland.

Moy Park said at the time that all industrial waste water was strictly controlled and treated before discharge and that it would undergo additional treatment by Northern Ireland Water before being discharged into the waterways.

The discovery was made as part of a wider BBC investigation into pollution in Lough Neagh.

Britain’s largest freshwater lake has been hit by an algal bloom. toxic blue-green algae.

Sunday’s protest, in which activists “vomited” green mud, was meant to represent this blue-green algae.

Following the protest, Dr Laura Kehoe, environmental scientist and member of Slí Eile, stated that “industrial animal farming is not only the root cause of the Lough Neagh disaster, but also the root cause of greenhouse gas emissions, water pollution and the collapse of biodiversity across Ireland”.

“We simply cannot continue with the extreme damage caused by corporations maximizing their profit margins, literally at the expense of the planet,” she added.
