The EU’s top farm official is begging German farmers to stop mailing her milk.

Farmers have bombarded Agriculture Commissioner Mariann Fischer Boel with some 10,000 liters of milk to show their anger over an EU proposal to increase milk quotas that may cause prices to fall, her spokesman Michael Mann said Tuesday.

Most of the milk _ sent by regular mail and addressed to Fischer Boel _ had spoiled in transit, and some of the cartons had burst open, he said.

“We have to, unfortunately, throw it away,” Mann said. “We are conscious of their concerns, but we don’t think it’s a good idea and they should send it to a good cause.”

Fischer Boel pleaded with farmers in a message on her blog Monday to stop sending milk, saying she was happy to talk to them directly to find a solution to their grievances.

“If you would like to keep on sending milk, I can suggest that it would be better put to a good use in your local area,” she said.

German dairy farmers went on strike in May, refusing to deliver milk to creameries in protest against low prices at grocery stores. Major supermarket chain Lidl responded by raising its milk price.

Global milk prices have soared on growing demand for milk powder from emerging economies such as China, hiking European prices for cheese and ice cream.

But farmers claim that they haven’t seen this translate into more money for them. The milk mail protest was organized by a German dairy federation unhappy with EU plans to raise production.

EU farm ministers agreed to increase yearly milk quotas by 2 percent _ or an extra 2.84 million tons _ from April to help meet swelling demand.

Fischer Boel has suggested that EU nations consider scrapping production quotas altogether by 2015 to end decades-old production rules that don’t link output to how much farmers receive in prices or subsidies.
