The Food Standards Agency is reporting an outbreak involving 18 cases of illness from Salmonella goldcoast potentially linked to the consumption of whelks.Frozen and chilled whelks from a Kings Lynn based supplier are being recalled as a precaution. The same page provides useful information on how to avoid infection. For anyone who has consumed the affected whelks (indeed if this link is confirmed) this advice may be of course too late. Shellfish have been in the past and continue to be associated with infections from Salmonella and indeed viruses such as Norovirus – often polluted water is the cause. However this is sound overall advice for those handling food including the consumer and commercial food handlers such as restaurants.
