Dawn Meats in County Waterford has contacted Gardai about masked individuals manning the blockade outside its plant in Grannagh.
A spokesperson for the company described it as "a sinister and unsettling development" saying it demonstrates that these people are well aware of the illegality of their actions.
Protesters wearing balaclavas, sunglasses and scarves appeared on the gates on Monday morning just hours after a potential deal was agreed.
WLR spoke to protesters on the picket on Monday.
The spokesperson for Dawn Meats said:
"The use of balaclavas to hide the protestors' identity is a sinister and unsettling development. It demonstrates that these people are well aware of the illegality of their actions. It is depressing that the law of the land can be openly disobeyed with impunity.
If these protestors genuinely felt that they had right on their side, they would show their identities and face the consequences of their actions. Instead, they leave local farmers unable to sell their animals and hundreds of staff without work."
The protests over the past three weeks forced Dawn to temporarily lay off over 300 workers at the plant.
Meanwhile, restaurants are warning that beef could soon be off the menu.
CEO of the Restaurants Association of Ireland Adrian Cummins warned that if blockages aren't lifted soon, some restaurants won't be able to serve beef due to 'zero supply'.
