Apple

  • Pesticide residue

    medium

    Apples consistently rank high on the EWG's Dirty Dozen list; washing thoroughly or choosing organic is advisable.

  • Wax coating

    Conventional Apples often have edible shellac wax applied for preservation, which is safe but can trap pesticides underneath.

Watermelon

  • Pesticide residue

  • Foodborne illness

    low

    Melons grown on the ground can harbor bacteria on the rind; always wash the outside before cutting to prevent transferring bacteria to the flesh.
