Horse owners have been warned of the dangers of the seeds and young shoots of the sycamore tree, which can be toxic for horses. The warning comes from the Flemish horse association PaardenPunt. “Keep your horse away from sycamore seedlings, and remove trees growing in the vicinity of the field,” the association advises. Horses can become sick by eating the seeds, which fall in autumn and have a distinctive helicopter shape, and the shoots, which are beginning to appear now. Three out of four horses affected die sooner or later. Seven cases of horses being poisoned by sycamore were reported in the first week of April alone, most with a fatal outcome.
