2 Sisters claims it is “business as usual” at its Dial Lane site in West Bromwich following news that health authorities are investigating four cases of TB infection at the factory.

Local newspaper the Express and Star reported this morning that Public Health England is currently investigating cases of TB at the 2 Sisters site.

However, 2 Sisters has downplayed the investigation, claiming the cases are historic, dating back to 2010, and that all cases of TB are being investigated by the relevant Public Health Authority as a matter of course.

2 Sisters said it took the health and wellbeing of its workforce very seriously and was assisting PHE fully with its enquiries. “As a precautionary measure, we are working with PHE to co-ordinate some educational materials and screening sessions on site,” a spokesman said.

There was absolutely no impact on food quality or safety, and it was business as usual at the site, he added.

Public Health England West Midlands said it was taking precautionary measures to check the health of staff who may have come into contact with co-workers while infected. “Testing will be conducted as a precaution and we are working closely with the management of 2 Sisters Food Group Ltd to ensure that the best advice and support is provided for all staff members,” said Dr Naveed Syed, PHE West Midlands consultant.
