Spanish cucumbers were found not to have the lethal strain of E. coli which has killed 16 people, five in Germany and one in Sweden.
German authorities pointed to Spanish organic cucumbers as the outbreak source. The Spanish government has demanded compensation for their growers, who were forced to destroy tonnes of vegetables.
BBC News website readers in Germany and Spain share their views.
Scott Rooney, Saarland, Germany
I live in a part of Germany which is not affected by the outbreak but we, and a lot of people I know, have stopped eating all raw vegetables and have also stopped buying cucumbers, tomatoes and all types of lettuce.
The vegetable sections at most shops are empty - people are not buying fresh produce at the moment.
One local greengrocer has already gone bust.
We have also stopped eating fruit which cannot be disinfected and skinned, for example strawberries. This may be a bit paranoid, but until a source has been found, no-one can tell what is safe to eat.
In normal outbreaks of this kind the source is found quite quickly, leading me to believe that it is not just one thing but many things, or a very high rate of cross-contamination.
Even though it looks like it is mostly connected to north Germany, it may be just this paranoia that is keeping it out of Saarland.
Leon Cohen, Castell de Ferro, Spain
I live in a province in Spain where a lot of farmers grow their vegetables. They are very angry - they feel what has happened is unjustified.
The system of control here is strict. They think the motivation behind the comments made by the German authorities about the source of the outbreak is about business. They think this is unfair competition.
At the moment there is no clear picture as to what is likely to happen with the current production of melon, watermelon, tomatoes and green peppers.
Prices have dropped dramatically on all vegetables grown here.
The national market is their only outlet and the farmers have to suffer now and in the future for something which is out of their control.
There is a real feeling of desperation and plenty of anti-German feeling here in Spain.
Martin Alejandro Carmona Selva, Barcelona, Spain
People here are angry with the German government because it has really hit the Spanish farmers. It was unfair to blame the Spanish when it seems they had nothing to do with the situation.
I don't eat cucumbers as I don't like them. But I do eat organic tomatoes and lettuce and I will keep doing so. I don't think the problem lies here in Spain. I feel the most probable cause may be somewhere along the distribution chain.
But the real issue is the fact that some items of food travel an awful long way. A solution would be to produce, buy and eat local food.
You can't grow tomatoes in Berlin city centre, but you could grow them much closer than Almeria in Spain for sure.
I eat yoghurt and butter from Germany. My orange juice is made in Britain with oranges from Valencia, probably. And I think it's a joke that because I'm eating organic produce I'm helping to destroy the environment because of the long distances my food has to travel.
Jon Gill, Schleswig-Holstein, Germany
I live in Germany's northern state of Schleswig-Holstein near to the city of Flensburg, one of the worst-affected areas.
Everyone is talking about it and there is without a doubt a sense of worry amongst the community.
Almost everyone I know here is avoiding such products and I can't help worrying myself.
