Please choose the correct ending to complete the given sentence: Health: [header] How to avoid lead exposure from food [title] Always wash fresh produce before eating it. [step] Lead was in paint and gasoline for many decades before regulatory rules came into effect in the late 1970s. As such, soil is frequently contaminated with lead dust, especially in heavily industrialized areas.

Ending1: Washing those types of produce keeps the environment clean and promotes fresh grass growth in upcoming spring weather. [substeps] There are several ways to properly wash the produce, including scrubbing with a garden hose, using soap and water, and using a large, heavy brush. Ending2: Mineral crude sources like cow's milk can harbor lead. Remove all of these substances before eating your light equipment. Ending3: To protect yourself and your children, always thoroughly wash fresh fruit and veggies before you eat them. [substeps] Not only can lead contaminated dust settle on produce, but fruits and veggies can also absorb lead from the soil-making it impossible to wash off. Ending4: Clean your produce and always rinse it thoroughly under running water. Water will carry lead around the outside and won't be a problem in the long run, although in the long run, lead in canned food may be beneficial.
