I sometimes give my ants living insects, but they are small, proportional to their size. Ants hunt mostly insects smaller than them, and only the large colonies, able to hunt in packs, occasionally also some a bit larger, but no European ants would be able to catch a living locust. (until it would be really unfortunate and fall directly on Formica mound)
Of course the risk of infecting by something deadly is small, but it exists - it's like allowing the house cat to hunt mice, well, they like that and MOST of them aren't hurt. Remember that SOME natural ant colonies, even large, really die from diseases and parasites, although they are minority.
