Daylesford is recalling Rosemary & Thyme Roast Ham and Smoked Black Ham because Listeria monocytogenes has been found in the products.
The Food Standards Agency (FSA) said all pack sizes with use by dates between July 20 and 25 were being recalled.
Problems were detected during routine weekly laboratory analysis of ham production. A spokesperson for Daylesford said that recalling the product had been a ‘precautionary measure’ and that all further tests had come back clear.
Point of sale notices will be displayed in all retail stores that are selling these products and consumers are advised to return the ham for a refund.
Symptoms caused by the organism are similar to flu, including: high temperature, muscle ache or pain, chills, feeling or being sick and diarrhoea. In rare, more severe cases, it can cause meningitis.
Individuals with weaker immune systems, aged 65 or over, pregnant women and babies who are less then one month old, are at increased risk.
Daylesford have confirmed that no other hams were affected.
