Quotes from the BBC version (the HuffPost one gives me a 404 error):

Quote:

The samples came from 487 businesses, including restaurants and supermarkets.

A BBC Freedom of Information request to the FSA revealed that in total 73 of the contaminated samples came from retailers - including three supermarkets. A further 50 came from restaurants, while 22 originated from manufacturing or food processing plants.

(and)

An FSA spokesman said it was up to the relevant local authorities - which procured the samples before sending the results to the FSA - to lead individual investigations and take "appropriate action" such as prosecutions.

He added the results were "not representative of the wider food industry".

(and)

According to the FSA, the inclusion of DNA at a proportion of 1% or greater should be considered consistent with "deliberate inclusion".

A bit pointless having a body like the FSA if it's not in charge of making the investigations and running prosecutions.
