Help! I fed my pacman frog a wild caught cricket! What should I do!

[balloones]

I put a wild caught cricket we found and the street in my pacman frogs cage and I was about to take it out but the frog ate it! What should I do! I read that these wild crickets and transmit diseases and even kill the frogs if it has too many toxic chemicals! Is there anything that I can do to protect it against from the harmful substances that the cricket may be carrying or should I visit the vet? Am I worrying too much or is this a serious threat?
