Because of health and economic concerns, more people are growing their own fruits and vegetables. Individuals can control what pesticides and fertilizer are used. Processing facilities because of improper sanitation procedures have contaminated produce causing serious illnesses. Pesticides, bacteria and costs have made people turn to growing their own food.

Backyard or community gardens are not immune to contaminates, however. Urban gardens may be growing in soil that contains heavy metals that have leached into the soil. Large urban areas because of past or existing manufacturing can have high levels of soil pollutants as well as atmospheric. Soil is an excellent filter and studies have concluded that plants do not absorb unacceptable levels of heavy metals or pesticides. Although, many think any level contaminate is too much. Soil from rural areas will not contain as high a level of contaminates.

Gardeners can have their soil tested to relieve anxiety or buy organic soil and build raised beds. Many communities will spray pesticides to control the mosquito population. Mist can settle on exposed fruits and vegetables. Rinsing well will remove any topical contaminates. Neighbors may be spraying pesticides and the mist may become airborne and settle on the plants. Regardless of, where the fresh produced was raised washing thoroughly before eating is a good idea.
