Kids may try to convince their parents that broccoli is toxic, but it actually is for livestock. Brassica plants, which include kale, rape, cabbage, broccoli and mustard, are toxic to livestock, according to the Ontario Ministry of Agriculture, Food and Rural Affairs. Brassicas contain a number of toxic chemicals, including glucosinolates, which are present in young growing plants and seeds at the highest concentrations. When consumed, they can cause goiter, hypothyroidism, poor growth rates and reproductive failure. Glucosinolate metabolites can also cause colic and diarrhea. Herbicides may be needed to control mustard from contaminating hay and pasture fields in the first year after seeding.
