Chocolate Shoppe Ice Cream is expanding its recall of cookie dough products that come from an outside supplier due to possible health risks, according to a release.

The Madison-based ice cream company is recalling products containing chocolate chip cookie dough pieces purchased from Aspen Hills, officials said. Aspen Hills issued a voluntary recall for their cookie dough pieces out of an abundance of caution last month.

Aspen Hills expanded its recall to include product produced before the initially-affected batches, according to the release.

Officials said the cookie dough was voluntarily recalled because the company found “lapses in its food safety system,” such as inadequate documentation and failure to wear proper uniforms, that could have led to the product being contaminated.

No illnesses have been linked to the company’s products, and none of the cookie dough has tested positive for listeria, according to the release.
