NORFOLK, Neb. (AP) — Two related companies in Norfolk have settled allegations regarding the production and sale of what federal regulators say are unregistered and misbranded pesticides.

The Environmental Protection Agency says Customer Feed Services Corp. and Earthworks Health will pay civil penalties totaling more than $74,500. The EPA says it learned after a 2011 state inspection that the companies were selling or producing diatomaceous earth and copper sulfate products. The EPA says such products have to be registered with the EPA and must be properly labeled to avoid causing unintentional harm to people or the environment.

Company owner Larry Smith said Friday the EPA has very strict regulations about what can be said in distributing these products, and “we omitted some of this terminology in the distribution of these safe and natural products.”
