A video posted to Facebook on 8 January 2017 appears to show people opening the foil packaging covering Ferrero Rocher candies and discovering small, red worms inside which appear to be fly larvae:
Brian Brown, curator of entomology at the Natural History Museum in Los Angeles said it is unlikely to find fly larvae in candy wrappers. "Nothing’s impossible. But that looks like it was something that was set up."
Ferrero Rocher chocolates are a popular candy sold globally. They consist of a chocolate and hazelnut crust and contain a wafer filling. The company has in the past been the focus of Internet-savvy consumers who claim to have opened their chocolates only to find bugs inside. In 2015, another video that went viral on Facebook (and has since been taken down) made similar claims about finding worms in the candy. At that time, the company responded as follows:
We appreciate you bringing this to our attention as we certainly don't want our fans to experience this or any type of problem with our products. The video you shared reflects a problem that can sometimes occur with food products, called Infestation. Infestation is a problem which can occur during the storage and sometimes the distribution of food products when the products are not stored in ideal conditions. Ferrero has comprehensive pest management programs in place at each of its manufacturing facilities worldwide. In addition, at several stages during the manufacturing processes, insects would not be able to survive given the high temperatures and machinery used. Although we print proper storage instructions on all of our outer cartons and each consumer package, we have no control over the storage conditions and stock rotation policies of our distributors and retailers. Infestation can occur if the product is stored with or near infested food products or pet products. Pests, such as the ones in the video, penetrate nearly any type of confectionery packaging on the market today, except glass or metal.
Because the packaging of the candy in the most recent video appears to have been tampered with before the recording started, it is impossible to tell whether there were in fact bugs in the candy, or whether the video's makers put them there to create a hoax.
