It is great to grow your own food as it tastes good, it is fresh and it helps our children understand where food comes from. You can still get food poisoning or contamination from your own produce but this can be avoided with bit of careful planning.
Remember not to put ‘grey’ water from the house, such as the washing machine water, on to fruit, vegetables or herbs growing in the garden. Don’t store grey water as microbes will grow in it and don’t use water from the washing up or dishwasher as it has too much fat and other solids which can be bad for plant growth.
Don’t locate your garden near any rubbish piles or bins that may contain chemicals that could leak into the garden or attract vermin. I Carefully choose the garden site for hazards, for example, if you have an older building avoid using soil that could have been contaminated by scrapings of lead paint many years ago.
Make sure the compost you buy is treated and if you make it yourself ensure it is well composted; this not only kills any weed seeds but also helps kill food poisoning bacteria. Prevent easy access by vermin and pests., like mice and rats, which can spread disease. Never use any type of manure on food plants that hasn’t been thoroughly composted as it will be contaminated with bacteria some of which can make you sick.
Take precautions to protect your vegetable garden from entry of domestic and wild pests. Watch for evidence of invasions and discard damaged crops.
Minimise the use of garden chemicals and make sure you stick to the instructions for use. Use exactly the amount recommended on the label and don’t spray other areas of the garden in windy conditions in case the spray drifts onto fruit and vegetables. Some chemicals will have withholding periods before you harvest any fruit or vegetables that have been sprayed so that there are not residues in the food when consumed.
