Chicago Soybean and Corn both hit a 30-month high Wednesday, boosted by Argentina's port worker strike, which has disrupted the country's crop shipment.

Wheat prices also strongly rebounded after Tuesday's fall.
The most active Corn contract for Mar delivery gained 3.25c, or 0.49%, to 6.6925 per bushel. Mar Wheat hiked 27.25c, or 3.26%, to 8.63 per bushel. Mar Soybean rose 6c, or 0.42%, to 14.38 per bushel

Market traders noted that Argentine port workers, who have been on strike since the prior week, are blocking dozens of ships from the country's main terminals Alberto Jacobson. As a result, buyers have to turn to the United States for Corn and Soybean. Argentina is the World's 2nd largest exporter of Corn and 3rd largest Soybean supplier.

Wheat staged a Strong rebound on the day, as the market worried that cold weather could damage the Winter Wheat crop in the United States. According to weather forecast, bitter cold weather is moving into the plains for the next few days.

Besides, market talks that North Africa and Middle East countries would continue to stock up on food items added to the positive tone. Wheat has climbed 7.1% so far this year on increased demand.-Paul A. Ebeling, Jnr.

Meat and Livestock Australia chief economist Tim McRae said demand was growing steadily for lamb, beef, pork and chicken as the world economy recovered after the Global Financial Crisis.

Here are the must own stocks as Food Prices keep rising

Olam International, Noble Group, Wilmar International

Singapore listed commodities companies are set to become the rising stars of the exchange in 2011 and will become global players of significant importance.
Olam International Ltd, Wilmar International Ltd and Noble Group Ltd are most likely to lead the charge as the benefit from home grown markets in ASEAN, China and India, where the world's largest populations are consuming more and more of the world's food supply.

Cash Flow is on the rise at Noble and Olam, both have successfully made the switch into production from trading, have been expanding ever since.
Olam is the world's largest supplier of cashews and sesame seeds, and is among the biggest sources of cocoa, rice, peanuts and cotton. It operates in 64 countries.

Noble is Asia's biggest supplier of raw materials. Only 22 percent of its revenue comes from agriculture, with the remainder coming from materials such as iron ore.

It has invested heavily in mines and processing.

Wilmar is Asia's leading agribusiness group and the world's largest integrated palm oil company.

Golden Agri-Resources Ltd is the world's second largest palm oil plantation with a total planted area of 435,000 hectares (including small holders) as at 30 September 2010, located in Indonesia. It has integrated operations focused on the production of palm-based edible oil and fat products.

Demand is expected to grow because of demand for biofuels, which is part of the reason the company bought the sugar and renewable energy businesses from Australia's CSR.
