Is this flour safe to use?

Toast

I bought a 25-lb. bag of all-purpose flour.  I didn't realize until I got it home that it had a small box cut in it, that went through the bag, so the bag had a slight opening in it.  Is it safe to use, or should I just purchase more flour?

No one here can guarantee it is safe but I can tell you that, without a doubt, unless I spotted mouse dropped or some other obvious sign of contamination, I would just use it.
