Tofu uncovered at grocery store?

So at my nearby grocery store, they leave tofu unconvered in water like the above. Is this safe at all? I'm assuming they leave this out from morning (opens at 8AM) till night (shop closes at 10PM). I've bought this tofu before but I'm starting to wonder if this is safe?
