Dust is dirty and most oftentimes a nuisance, this gives it the strongest negativity of the word provided. The action of eating is a neutrally connotated word, as it is a regular habit needed for survival. Hands are neutral as there are seemingly just a part of the body. Lastly, sweets are seen as delicious and pleasurable, which gives it a positive connotation. So, the only negative word here is dust.
I hope this helps :)
