Snails don't cause any problems anyway (unless you're daft enough to add a snail killing liquid and suddenly have hundreds of dead ones decomposing). The only downside to them is that if you have huge numbers they can look unsightly, but if you're not overfeeding your fish, you won't have them in those kinds of numbers.
I agree it will have been the holiday block that's given them enough food to reproduce madly.
Pour boiling water over the veg, leave it for a few minutes and it should sink; if not stick a teaspoon (make sure it's a stainless steel one) or a piece of the lead strip you get on plants.
