A gourmet bakery in Lincolnwood specializing in European style pastries is recalling all its desserts made after Nov. 1 because of a food poisoning outbreak that has sickened 100 people.

Rolf’s Patisserie’s desserts, which include tiramisu, cakes, tarts and decorated cookies, might be contaminated with Staphylococcus aureus, a bacterium that produces toxins that can cause nausea, vomiting, stomach cramps and diarrhea. The illness usually last one to two days, though in severe cases it might last three days.

The Food and Drug Administration said Friday that 30 cases were reported in Illinois and 70 in Wisconsin.

It also warned consumers that desserts purchased at grocery stores might not have Rolf’s Patisserie label but that the company distributes its products to retail chains, wholesalers and over the Internet. Rolf’s said it has alerted its distributors, but consumers should ask about the source of the desserts before buying them.
