Check the ground around your building for paint chips. Throw them away where children cannot get them. Feed children before sending them out to the garden or playground. Help keep children generally healthy through a good balanced diet. One that is high in fiber, calcium and iron and low in fat will contribute to good general health and may help specifically by preventing the absorption of low levels of lead by the body.
Some foods containing calcium are milk, whole or skim, cheese, buttermilk and yogurt.
Foods that have high iron content are lean beef, lamb, liver, kale, spinach, swiss chard, watercress, and turnip and beet greens. If children will be actively gardening, consider planting in raised beds filled with clean soil and compost. Give kids their own work gloves to wear while gardening. Have children ages 1-6 tested yearly for lead. This can be done at a public clinic or through a private physician.
