Grupo Día, which has 7,400 stores, has recalled a batch of canned sardines in olive oil in Spain and Portugal because of botulinum toxin.
The product comes from Portugal and was distributed in Spain. No illnesses have been reported.
Foodborne botulism, caused by eating food that was improperly processed or held at improper temperatures, is rare but potentially fatal if not diagnosed rapidly and treated with antitoxin.
Grupo Día officials said the withdrawal is a precautionary measure due to a possible sterilization defect.
The Spanish multinational company specializes in the distribution of food, household and personal care products. It operates in Spain, Portugal, Argentina, Brazil and China with almost 7,400 stores.
The Spanish Agency for Consumer Affairs, Food Safety and Nutrition (AECOSAN) issued a statement saying it had learnt that more than 24,500 cans of sardines had been recalled.
