How do I claim for the moldy toilet paper I bought?

Food safety problems usually occur, and our way of safeguarding rights is: 1. Keep the evidence and negotiate with the merchants for compensation and settlement; 2. Call the national unified food and drug supervision and administration department's complaint hotline "1233 1" or 123 15 consumer protection hotline to complain to the consumer association or the relevant administrative department; 3. Bring a lawsuit to the people's court.

For complicated food safety legal disputes, it is recommended to consult a professional lawyer.
