Starter blew off

Hi all,
I'm brewing a big american barleywine today, and I stepped up my original yeast starter with a 2nd 3 litre a few days ago. It blew off a litte, I don't think I lost a great deal of yeast, what I'm more concerned about is the crusty yeast that's formed around the lip of my 1 gallon jug. It was all covered with foil, but it gives me the heebie jeebies pouring through that. Is there any worry of contamination or am I being too concerned? I will use a flame around the lip before pouring.
cheers and hoppy holidays!

Your only using a 1 gallon jug but you added 3 MORE litres of starter? Where is there room for the wort?! I'm confused :/

I decanted the first starter so there was only yeast, then pitched it into a 3 litre starter
