The European Union will not agree to put consumers and the environment at risk by lowering food safety standards in free trade negotiations with the United States, the bloc's top trade official has said, pointing out that documents leaked Monday do not represent the final deal.

"No EU trade agreement will ever lower our level of protection of consumers, or food safety, or of the environment," EU Trade Commissioner Cecilia Malmstrom wrote in a blog post.

The information, published by Greenpeace, "reflects each side's negotiating position," she said, adding that opposing views should come as no surprise. "In areas where we are too far apart in negotiation, we simply will not agree," she added.

Malmstrom said that the most recent EU texts refer to the principle of precaution - a level of consumer protection that Greenpeace considers to be under direct threat in trade talks - and argued that the industry is not getting favorable treatment in the negotiations.

According to leaked documents, the U.S. government has pressured the EU in negotiations for a joint trade deal aimed at loosening both environmental and consumer protections, German media outlets reported.

The environmental group Greenpeace provided the documents to the Sueddeutsche Zeitung and German broadcasters WDR and NDR in advance of plans to broadly disseminate the 240 pages of the Transatlantic Trade and Investment Partnership (TTIP) documents on Monday.

Washington has threatened to block efforts to ease the export of European cars if the EU does not agree to allow the sale of more U.S. agricultural products, the newspaper said. The move would hamper EU consumer protections intended to block genetically modified organisms (GMOs) and meats from animals treated with hormones.

Greenpeace also said the deal would limit the ability of regulators to take preventive measures, alleging that big business had been heavily involved in drafting the agreement, citing its previewing of the documents.

Negotiators from the U.S. and EU said Friday after talks in New York that they remain hopeful that the TTIP trade agreement will be completed this year despite headwinds from the popular opposition, the U.S. elections and the looming vote in Britain to determine its fate in the EU.

The TTIP has faced strong opposition from the public both in Europe and the U.S., where anti-free trade rhetoric has gained prominence among candidates in both main political parties ahead of the November elections.

U.S. President Barack Obama has made trade a key item on his agenda during his remaining months in office, pushing for the deal in Germany last week while attending an international trade show in Hanover alongside German Chancellor Angela Merkel.
