The Rosderra Irish Meats facility in Clara, Co. Offaly, has seen four members of staff test positive for Covid-19.
The cases were confirmed after testing was carried out on 68 workers there.
The testing was carried out through a weekly testing programme for staff in the food processing sector that was introduced by the National Public Health Emergency Team (NPHET).
A full site test was carried out last Friday (August 21), Rosderra said.
Rosderra said it is working to identify the source of transmission.
The company noted that it has a number of measures in place to deal with infection control, including supervised distancing, mandatory face coverings, daily temperature testing and staggered working hours.
Communications to staff are in the relevant languages, and employees are informed not to come to work when feeling ill or experiencing Covid-19 symptoms, Rosderra said.
The pigmeat processor also added that a full site risk assessment screening test of 400 staff at its larger plant in Edenderry resulted in no positive cases.
ABP Clones
In related news, ABP has confirmed two cases of Covid-19 among its workforce at its plant in Clones, Co. Monaghan.
The beef processor said that it is in the process of testing all staff members at its Clones processing facility, which it said is a “precautionary measure” that will be carried out by a private company in conjunction with the Health Service Executive (HSE).
ABP had been notified of a positive case among one staff member and, following HSE testing of that worker’s close contacts, the business was notified of a second case.
