We had a flash flood 6 weeks ago, with our garden under a foot of water for a couple of hours. We are unsure of what contaminants were in the water, so I've discarded everything that was directly in the ground (radish, spring onions etc), but I don't know about my tomatoes, runner beans and squashes. The fruits, such as were were back then, did not come into direct contact with the water as each plant is in a large pot. There seems to be conflicting views out there on whether these crops are safe to eat now that we are getting close to harvest time. It would be a shame to discard these as the tomatoes in particular look like they will be a bumper crop this year! If anyone has any thoughts, I'd be grateful.
