Two British authorities have issued food safety warning on Sunday about Loyd Grossman Karma sauce that is contaminated by the bacteria botulinum and may cause botulism. The Health Protection Agency said that it \"have identified the toxin that causes botulism from a used Jar of Loyd Grossman Korma sauce\", which \"follows two cases of botulism in one family in Scotland where the contaminated jar of sauce was discovered.\" The Food Standards Agency said that so far only one jar is known to have been contaminated, but the agency is advising people not to eat products from this batch as a precautionary measure. The affected batch is \"350g jars of Loyd Grossman Korma sauce with a \'best before\' date of February 2013.\" A full recall of this product batch has been issued and the sauce is being moved from shop shelves. Dr Kathie Grant, a botulinum toxin expert at the HPA, said: \"We urge the public to take heed of this message and ensure that they immediately dispose of this product and to be aware of the signs and symptoms of botulism, which include blurred vision, difficulty swallowing, headaches and muscle weakness.\"
