Sweet mix ups and packaging blunders

Even the biggest sweet makers get things wrong. Some blunders are funny, some are serious, and a few led to recalls across whole continents. Here are the sweet mix ups and packaging mistakes that made the news, and what the companies did next.

Making sweets is a precise business, and the label matters as much as the recipe. When things go wrong, the result can be a recall, a court case or a lot of sticky wrappers.

Missing nut warnings

Cadbury had two labelling problems in 2007. On 10 February 2007, it recalled some of its Easter eggs, because they had been made in a factory that handled nuts and the packaging did not make that clear. Cadbury said the products were perfectly safe for people without nut allergies.

That September came a second recall. A printing mistake at the Somerdale factory left tree nut allergy warnings off 250 g Dairy Milk Double Chocolate bars, and thousands of bars were recalled, Cadbury's second recall of chocolate bars in two years.

Plastic in a Snickers

In February 2016, Mars recalled chocolate bars in 55 countries after a piece of plastic was found in one bar. The recalled products, Mars bars, Snickers, Milky Way Minis, Miniatures and some Celebrations boxes, had all been made at Mars's factory in Veghel, in the southern Netherlands, with best before dates from 19 June 2016 to 8 January 2017.

A mouse in a Topic

In 1997, a Topic bar was found to contain the remains of a mouse. An investigation traced the contamination to a supplier in Turkey, and the UK courts ruled that Mars could not be held negligent under the Food Safety Act, because it had exercised due diligence in inspecting the supplier's operations: see sweets from the 1960s

Lead in a sour chew

In January 2011, the US distributor of the Toxic Waste Nuclear Sludge chew bar, made in Pakistan, recalled it because of lead contamination, first detected by the California Department of Public Health: see the history of sour sweets

The toffee that stuck

Not every blunder is dangerous. Quality Street's Toffee Penny stuck to its cellophane wrapper for years, because toffee draws in moisture, until in 1967 a foil backed paper wrapper solved the problem: see why are sweets wrapped?

Bigger scares and changes

Some problems were far more serious, such as the Cadbury salmonella scare of 2006 and the Kinder salmonella recall of 2022: see the Cadbury salmonella scare of 2006 and the Kinder salmonella recall. Others were deliberate changes that customers noticed straight away: see the Toblerone gaps

Questions and answers

Why did Cadbury recall chocolate in 2007?

Twice, for labelling errors. In February 2007 some Easter eggs made in a factory that handled nuts did not make this clear, and in September a printing mistake left tree nut allergy warnings off 250 g Dairy Milk Double Chocolate bars.

Why did Mars recall chocolate bars in 2016?

A piece of plastic was found in one bar. Mars recalled Mars bars, Snickers, Milky Way Minis, Miniatures and some Celebrations made at its factory in Veghel in the Netherlands, in 55 countries.

Why do allergy labels matter so much on sweets?

Because people with allergies rely on the label to avoid the foods that can make them ill. Both Cadbury recalls of 2007 were about nut warnings that were unclear or missing, although the company said the chocolate was safe for people without a nut allergy.
