* Groups concerned about impact on government health, safety regulations
* Some see pact as "backdoor" attempt to weaken EU privacy rules

WASHINGTON, May 29 (Reuters) - U.S. consumer groups plan to raise concerns on Wednesday about a proposed free trade agreement between the United States and the European Union, which they fear could weaken important government health, environmental and food safety regulations and undermine privacy on the Internet.
Negotiations on what would be the world's largest free trade pact are set to begin in July. A U.S. government panel led by the Trade Representative's office is holding hearings this week to finalize its goals for the Transatlantic Trade and Investment Partnership, or TTIP.
About 60 supporters and critics of the proposed deal have been given 10 minutes each on Wednesday and Thursday to make their cases and answer questions from the panel.
Since tariffs between the United States and the EU are relatively low, the most difficult part of the talks will be reducing regulatory and other "behind-the-border" barriers that impede trade in sectors ranging from agriculture to chemicals to autos to finance.
That worries consumer groups such as Public Citizen, which says the United States and the EU have different regulations because the concerns of the citizens in those countries are not the same. For example, EU consumers have voiced stronger objections to genetically modified food than their U.S. counterparts.
"Trying to eliminate a big swath of regulatory differences via a trade deal would have a democratic cost because you're taking away a power from the electorate," said Ben Beachy, research director at Public Citizen's Global Trade Watch.
Meanwhile, U.S. plans to ease the movement of electronic data across borders have alarmed Internet activists, who see that push as a "backdoor way" for U.S. companies such as Google Inc and Facebook Inc to get around EU privacy rules that have restricted their businesses in Europe.
"We've made it very clear that we're not to give up privacy for the sake of a few digital dollars," said Jeff Chester, executive director of the Center for Digital Democracy.
The Transatlantic Consumer Dialogue, which includes consumer groups on both sides of Atlantic, also has urged the two sides to tread carefully in talks on financial services, an area that EU member Britain is especially keen to pursue to bolster the position of London as a major world financial center.
"It is essential that consumer protection measures, many of which are still under development in response to the collapse and rescue of major portions of the banking system, should not be pre-empted by this agreement," the group said in a brief.
Meanwhile, other groups hope to use the hearing to push their special concerns onto the U.S.-EU negotiating agenda.
Oceana, an international ocean conservation group, wants the two sides to limit subsidies that promote overfishing and reduce illegal, unreported and unregulated fishing around the globe.
Together, the U.S. and the EU account for slightly more than 16 percent of the global catch by weight and are in the top five importers and exporters worldwide.
"If you can fix a problem in those two (economies), it makes a huge difference," said Jackie Savitz, a deputy vice president at the conservation group. "This presents a chance to say 'All right, what do we want to do about fisheries issues?'" (Reporting by Doug Palmer; Editing by Lisa Shumaker)
