Not very, botulism is primarily caused by improperly canned foods. Most pizza parlors use fresh ingredients on their pizza. Tomatoes are too acidic, typically, for the botilinum bacteria to grow in canned tomatoes, usually the only canned ingredient at some pizza parlors that don't make their own sauce. You are more likely to suffer listeria from fresh mozzarella (only slightly, pasteurized milk is usually safe), or salmonella from improperly cleaned kitchens that process raw meats.
