J.M. Smucker Co. has initiated legal action against a Los Angeles-based online snack retailer, accusing the company of defaming its well-known Uncrustables sandwiches through social media posts. In the complaint filed on Monday in an Ohio federal court, Smucker alleges that the rival has been disseminating false claims about its products being nutritionally superior. According to the filing, these acts of defamation are damaging the brand and misinforming consumers.
