Parsnips
These contain toxic psoralens, which are potent light-activated carcinogens and mutagens not destroyed by cooking [Ivie 1981]. Parsnips contain psoralens at a concentration of 40 ppm, and Ivie [1981, p. 910] reports:
[C]onsumption of moderate quantities of this vegetable by man can result in the intake of appreciable amounts of psoralens. Consumption of 0.1 kg of parsnip root could expose an individual to 4 to 5 mg of total psoralens, an amount that might be expected to cause some physiological effects under certain circumstances...
