Found pink gue in tarantulas tank!?

She's about 5 years old a red/rose chillian , she last molted around Christmas, I usually give her a locust ounce a week (if she eats it within 24 hours, if she doesn't I take it out, ) she has a heat pad, and plenty of water, has a nice plump abdomen (not to big either) seems all in all healthy, so did the locust I fed her yesterday, she ate it, but okay I found pink slime by her water dish, it wasn't as big as the locust so it couldnt have been the whole thing if she tori up or something, she seems fine right now, she's chilling and still moves if I touch her, I cleaned up the water dish and the surrounding area, but I'm worried if I made her sick or something, any ideas?
