Glitter Disaster

Let's start off by saying I am a new mother and my son is 7 1/2 months old. I had him in his walker and made the mistake of turning my back for literally a minute. I turned back and saw he had gotten to our coffee table and had opened my glitter tube!! I don't think he ate any because he barely had any on his hands but there's a huge pile of it on his walker. Should I be worried if he did possibly eat any? What should I do?
