"A small number" of employees have tested positive for Covid-19 at a food factory in Cornwall, Public Health England (PHE) has confirmed.
The cases at Pilgrim's Pride Ltd food factory in Pool were discovered as part of contact tracing.
Rachel Wigglesworth, Cornwall Council’s Director of Public Health, said: "Employees who need to isolate have already been excluded from work and given support to isolate.
"We have been discussing their ongoing measures to ensure it is safe for staff to attend work as normal.
"However, if anyone does develop symptoms, which include a new continuous cough, high temperature or loss or change to their sense of taste or smell, they should self-isolate straight away.”
A spokesman from Pilgrim’s Pride Ltd. said: "Since March when Covid-19 restrictions were first introduced, we have been following government guidelines for food processing sites and we have updated them as and when amendments have been made.
"Furthermore, we have implemented additional measures where they bring benefit including the installation of thermal cameras.
“We are working closely with PHE South West and Cornwall Council to arrange swab testing for a sample group in one particular area of production before deciding upon the need for any further screening."
