(Berkshire Hathaway item updated to correct a misreported figure. Warren Buffett's holding company eliminated a stake in Travelers of about 27,000 shares, not 270,000.)

OMAHA, Neb. ( TheStreet) -- Warren Buffett's Berkshire Hathaway ( BRK.B) got out of health insurance and into garbage collection and medical devices during the first quarter of 2010.

According to the seasonal disclosure of its investment holdings, filed with the SEC Monday, Berkshire killed its stake in WellPoint ( WLP) during the first quarter, selling all 1.3 million shares. Buffett's holding company also liquidated sizable stakes in UnitedHealth Group (1.2 million shares) and regional bank SunTrust ( STI) (2.4 million shares).

SunTrust shares fell sharply in Tuesday trading. Late in the session, the stock was changing hands at $27.72, down $2.16, or 7.2%.

Shares of WellPoint and UnitedHealth were only modestly lower Tuesday, losing 0.2% and 0.8%, respectively.

Buffett continued to sell shares in Gannett ( GCI), and notably sold stock in Kraft ( KFT), a long-time Berkshire favorite that came under fire from Buffett for its purchase of Cadbury.

But Republic Services ( RSG - Get Report) apparently caught the Oracle's attention. Berkshire increased its interest in the waste collector and recycler to 10.8 million shares from 8.3 million shares in the prior quarter. Meanwhile, he bought up shares of medical device maker Becton Dickinson ( BDX - Get Report), hiking his interest by 200,000 shares to 1.7 million.

The bullish calls for Buffett were relatively scarce in the first quarter, which comes as no surprise as his firm has sought to raise cash for the completion of its $26.7 billion acquisition of railroader Burlington Northern ( BNI). His only other raise came in shares of data provider Iron Mountain ( IRM - Get Report), a recent favorite of Berkshire's. During the quarter, the firm increased its holdings in the company to 7.8 million shares from 7 million.

Berkshire also eliminated a modest holding -- about 27,000 shares -- in insurance giant Travelers ( TRV - Get Report).
