- Use clean potting soil, available from nurseries, for your vegetables.
- Grow food crops in in raised beds, or use barrier fabric to stop roots growing into potentially contaminated soil beneath.
- Avoid growing crops directly adjacent to buildings and road verges.
- Rinse produce well to remove soil, in 1:100 parts vinegar to water.
- Remove outer leaves from vegetables like lettuce, and peel root vegetables like carrots.
The bottom line with this issue is that the health and environmental benefits of growing your own food far outweigh the small risks posed by growing in city soil.
