FIVE batches of Marks and Spencer potato crisps and some Ikea candies have been destroyed because of quality problems, China's top quality watchdog said yesterday on Consumer Rights Day.
More than 140 kilograms of M&S crisps imported from the UK by its Shanghai subsidiary last month contained excessive peroxide levels, an indication that they were stale, the watchdog said.
Consuming food with excessive levels of peroxide over a long period can lead to liver damage, vomiting and diarrhea, according to doctors.
The concentration of peroxide in oil or fat is useful for assessing the extent to which spoilage has advanced, the watchdog said.
A response from M&S Shanghai is expected on Monday.
More than 2,100 kilograms of Ikea's caramel candy bars imported from Denmark by Ikea Shanghai were destroyed as the products did not match accompanying documents and certificates, the General Administration of Quality Supervision, Inspection and Quarantine said.
The products were among 171 imported food and toothpaste items returned or destroyed by the bureau in February.
They included beverages, wine, chocolate, biscuits, cheese, snacks and cakes.
The products were found to be past their expiry dates, contained excessive amounts of coliform bacteria or sulfur dioxide, heavy metals, additives or banned substances, had high acid levels, or there were labeling problems.
