A national product recall has now been issued by the importer, O Widmann and Company Limited, and customers have been promised a full refund amid fears they could cause suffocation, poisoning, and serious damage to the digestive system.
East Riding council in Yorkshire discovered the offending products, a lollipop tree garland, a tree topper and a star tree decoration, on sale in garden centres across the region during a routine investigation.
The trading standards manager told retailers that they appeared dangerous as they imitated food and a selection was taken away for testing.
Widmanns tested the product independently and came to the same conclusion.
The three products are a lollipop tree garland with product code L316552, a tree topper with product code M251968 and a star tree decoration, with product code L316554.
The council did not disclose which garden centres were involved.
