Euronews.net said Sunday the outbreak has made about 300 people ill and killed 10 people in Germany.
A spokesman for the European Union said the two greenhouses in Spain where the cucumbers were grown had suspended production pending water and soil analysis.
Most of the cases occurred in Germany, although others have been reported in Sweden, Denmark, the Netherlands and Great Britain.
Danish authorities told the Copenhagen Post they did not expect the problem to spread in Denmark, although they noted approximately 1,500 school children in Odense snacked on cucumbers Friday that had come from Mango Frut, the German wholesaler that sold the suspect cucumbers in Denmark, Germany and the Netherlands.
