BERLIN — More than 270 people in Germany have fallen seriously ill due to potentially deadly bacteria detected in imported Spanish cucumbers, but Madrid said Friday there was "no proof" it is to blame.
Russia meanwhile is considering an import ban on all German vegetables in the wake of the E. coli outbreak.
The Robert Koch Institute, Germany's national disease centre, said more than 60 new cases of haemolytic uraemic syndrome (HUS) had been reported in the past 24 hours, bringing the total number in Germany to 276. At least two people have died.
Two German tourists have also been hospitalised in Austria with the infection, a health ministry spokesman told the Austrian news agency APA.
The men spent two weeks cycling to Austria from north Germany before coming down with symptoms, the spokesman said.
In Switzerland, authorities said a woman returning from northern Germany also appeared to be infected with the same food-borne bacteria.
Enterohaemorrhagic E. coli causes HUS, which can result in acute renal failure, seizures, strokes and coma.
The German consumer affairs ministry said investigations were underway to track the precise origin of the contamination in vegetables which have been ordered withdrawn from the market.
German authorities have identified organic cucumbers from Spain as a source of the bacteria which has also led to food poisoning in Sweden, Denmark, Britain and the Netherlands.
But Spain's agriculture minister, Rosa Aguilar, said it was too early to blame her country and complained the accusations had caused "irreparable damage" to the sector.
"We do not know where the contamination may have taken place and the European Commission has made clear that it could have happened outside the country of origin," the minister said.
"Until now nothing has been proven and it has not been demonstrated that it happened in the country of origin," she said, adding: "Our level of safety and quality is extraordinarily high."
A spokesman for the AESA food safety agency in Spain said investigations were also underway.
"The Andalusian authorities are investigating to find out where the contamination comes from and when it took place," he said.
"This type of bacteria can contaminate at the origin or during handling of the product."
There has been no report of contamination within Spain, AESA said.
Russia's top health official said a ban on imports of vegetables from Germany was a possible option.
"Because the situation is ongoing and we do not know its causes or the mechanisms by which it is spread, we are examining the option of imposing a ban on German vegetable imports," news agencies quoted Gennady Onishchenko as saying.
There was no information about when a ban might be imposed, but Russians were instructed to avoid eating German vegetables and those planning to visit the country to only eat prepared food.
The German state of Saarland responded to the outbreak by banning the sale of all cucumbers from Spain.
Some supermarket chains, including the giant Rewe, also said they had withdrawn all Spanish-imported cucumbers from their shelves nationwide.
Officials meanwhile defended themselves against charges, mainly from farmers in northern Germany, that they had acted rashly in their warnings to the public.
Initial warnings had spoken of possible contamination in tomatoes, lettuce, and cucumbers grown in northern Germany, where most cases of food-poisoning have been reported.
"The protection of the consumer must always take precedence over economic interests," the consumer ministry spokesman said.
German vegetable growers have suffered losses of some two million euros ($ 2.8 million) per day since the middle of the week, a spokesman for the Farmers' Association said Friday.
"Trading is completely flat on the vegetable market in Hamburg," Germany's second city, according to Jochen Winkhoff, who heads the Association of German Vegetable Growers.
All growers are hard hit and "we have to destroy their produce because there is no demand," he added.
Denmark's veterinary and food products agency said Friday it had found contaminated cucumbers from Spain in the stocks of two wholesalers in the west of the country and ordered them withdrawn.
It advised consumers not to eat raw cucumbers from Spain or tomatoes and lettuce from northern Germany.
