Blackpool-based Great Northern Sandwich Co (GNSC) has recalled six chicken sandwich products because of possible contamination.

GNSC, owned by James Hall and Co, has recalled various products containing chicken, including sandwiches, because of a blue discolouration on the meat. The discolouration may indicate that the products are unfit for human consumption.

Three of the products are made by the eight-year old company for Spar. From its production facility in Blackpool, the company produces “an extensive range of high-quality sandwiches and wraps, supplying over 100,000 sandwiches per week to over 540 stores”.

A SPAR spokesperson told British Baker: “We have been working closely with the Great Northern Sandwich Co as it recalls a number of its sandwiches and rolls from SPAR stores in the North of England. We were alerted to a discolouration in the chicken found within the contents of the products and have been working with an independent auditor to review all our processes and procedures relating to this recall - they have not found any areas for concern.

"We have however suspended the use of all chicken from the producer who supplied the raw material until the conclusion of our investigation. We would recommend that if anyone has bought any of the affected products, they do not eat it, but contact the store they purchased it from for a full refund. No other SPAR products are known to be affected.”

We can confirm that those products affected by the incident include the Spar & Honest Crust Chicken & Stuffing Barm, Spar & Honest Crust Chicken Salad Sandwich and the Spar & Honest Crust Chicken Stuffing Sandwich. As well as the GNS Triple BLT, Chicken Salad, Ham & Cheese Sandwich, the GNS Chicken, Pesto & Sun Dried Tomato Sub Roll and the GNS Chicken, Bacon & Mayo Sub Roll.

The sandwiches are produced to order and delivered daily.
