Pastries, cakes, cookies, pies and other baked goods made by Rolf's Patisserie in Chicago are being recalled this Christmas Eve, over concerns that the sweets may contain Staphylococcus Aureus bacteria.

In a written statement released Friday, the U.S. Food and Drug Administration says the pastries have already sickened 100 people in Illinois and Wisconsin; and that any Rolf's product manufactured after November 1st may be contaminated as well.

Rolf's line of baked goods is sold online and distributed through national wholesale and retail chains, the FDA says, and may have been repackaged and sold under different brand names in supermarkets and through caterers and large institutions, such as nursing homes. The FDA recommends checking labels closely, and if you're unsure whether the products were made by Rolf's, calling the store where they were purchased.
