Beef, chicken, and pork producer Tyson Foods (NYSE: TSN) has accelerated nicely out of 'the danger zone' – the $10 price level – only to be confronted with another potential hurdle -- a change in consumer food preferences, due the H1N1 flu.

And one must underscore "potential" because while Tyson's food is safe, pork sales will still likely fall, due to customers switching out of pork.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Alcatel-Lucent (NYSE: ALU) shares rose even though it reported a wider loss for the quarter.
• American Express Co. (NYSE: AXP) posted better-than-expected Q1 results but warned of challenges.
• Blackstone Group (NYSE: BX) reported a net loss and slumping revenues for the first quarter.
• Center Financial Corp. (NASDAQ: CLFC) was downgraded following its Q1 earnings report.
• Cisco Systems Inc. (NASDAQ: CSCO) posted lower Q3 earnings that still topped analysts estimates.

Tyson Foods (NYSE: TSN) is up 9% in early afternoon trading as I write this. The company's second-quarter earnings release is driving the buying. According to this article, Tyson reported an adjusted loss of $0.05 per share. The market was expecting a loss of $0.06 per share. So I guess the market was pretty happy about that.

Wall Street was probably encouraged by something else as well. If you take a look at the actual release, head on down to the statement of cash flows. Last year at this time, Tyson generated $144 million in cash from operations during the six-month period. This year, the company made $407 million from operations. Some nice changes in working capital helped out.

I remember Toronto during SARS. As one of the harder hit areas, it was not a happy place. It was the end of winter, but that miserable, cold winter just didn't want to end. People walked the streets in a gloomy haze, afraid to take the subway and giving dirty looks to anyone brazen enough to cough in public. Worse, I couldn't even visit a friend in the hospital. All things considered though, in global pandemic terms, it was over relatively quickly. Let's hope swine flu will be the same.

In the meantime, let's put on our investors hats and see what's in store for some stocks:

Travel and tourist stocks
This is one of the worst hit areas, especially airlines, as people may cancel their travel plans. For example, AMR Corp. (NYSE: AMR) traded over 9 percent lower an hour after the open. Royal Caribbean Cruises (NYSE: RCL) was down over 15 percent. In fact UBS downgraded these airlines and hotels this morning: AMR, Continental Airlines (NYSE: CAL), Host Hotels and Resorts (NYSE: HST), Lasalle Hotel Properties (NYSE: LHO), Marriott (NYSE: MAR), United Airlines (NASDAQ: UAUA), US Airways (NYSE: LCC). Carnival Cruise Lines (NYSE: CCL) also declined considerably. Best to stay away from the sector.

Tyson Foods (NYSE: TSN) announced today that it will close its Ponca City, Oklahoma processed meats plant and shift its production to other company facilities. The poultry peddler announced this move as part of its continued attempts to improve its operating efficiency.

Reportedly, Tyson will attempt to find a buyer for the plant -- as it has been in contact with other companies but no sale has been completed.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Amazon.com Inc. (NASDAQ: AMZN) shares surged after earnings easily topped Q4 expectations.
• AT&T Inc. (NYSE: T) reported that its Q4 earnings fell while its revenue rose marginally.
• Boeing Co. (NYSE: BA) posted a big loss and lower revenue due to strikes and design changes.
• Caterpillar Inc. (NYSE: CAT) reported that Q4 profit fell despite higher revenue and lowered its guidance.
• Danaher Corp. (NYSE: DHR) lower Q4 profit topped analysts' estimates, sending shares higher.
• Eastman Kodak Co. (NYSE: EK) reported a Q4 net loss and announced additional job cuts.

Here's a quick look at some of Monday's earnings results:

Netflix Inc.'s (NASDAQ: NFLX) fourth-quarter earnings jumped 45% percent to nearly $23 million, or 38 cents per share, which surpassed analysts' estimates. Revenue in the period rose 19% to $360 million. The company ended 2008 with 9.4 million subscribers, a gain of 718,000 customers from the end of September. Shares fell $0.29, less than 1% Monday.

Amgen Inc.'s (NASDAQ: AMGN) fourth-quarter profit grew 15% percent to $961 million, or 91 cents per share, mostly due to lower expenses. Revenue was $3.75 billion about the same as last year. Results included $60 million in restructuring costs a year ago. Shares rose $1.22, or 2.3%, but fell in after-hours trading.

TheStreet.com's Jim Cramer says companies saddled with high debt loads can be found in every sector in every business.

Overleveraged. Too much debt. Need to pay down debt. How many times have you read that story?

You read it so much because it plays out every day and plays havoc with stock picking almost every time you see a savory stock down on its luck.

This weekend, as I went through the charts, I was amazed at how low some stocks have gone, stocks that I would normally say to just take a flyer on, but turn out to have so much debt, short- and long-term, that they are just too dangerous.

Consider these perhaps poisonous morsels:

Pfizer Inc. (NYSE: PFE) announced a deal to acquire rival Wyeth (NYSE: WYE) for $68 billion, or $50.19 a share, a 15% premium to Friday's close of $43.74. This cash-and-stock deal is the largest in the drug sector since 2000 and many see it as a precursor to a flourishing M&A season as the credit markets are slowly starting to improve. Pfizer also reported a 90% profit drop for the fourth quarter due to charges. PFE shares declined 3.4% in premarket trading, while WYE shares gained nearly 5%.

Barclays (NYSE: BCS) shares surged in London Monday after the firm reassured investors in a letter to shareholders it didn't need more capital. But France's BNP Paribas said it would take more cash from the government following a 1.4 billion euro ($1.8 billion) loss in the latest quarter. Finally, ING (NYSE: ING), the Dutch financial services firm, also received government aid as it is expected to announce it had a net loss of 3.3 billion euros in the fourth quarter, that it would cut 7,000 jobs, and that its CEO would step down. BCS shares gained over 44% in premarket trading and ING's gained over 19%.

Caterpillar (NYSE: CAT) and McDonald's (NYSE: MCD) are two Dow components set to report earnings this morning. CAT said its fourth-quarter profit fell to $661 million, or $1.08 a share, from $975 million, or $1.50 a share, in the year-ago quarter. Revenue rose 6% to $12.9 billion. For 2009, Caterpillar gave a a much lower guidance than analysts had expected, $2.50 vs. $4.35 EPS. CAT also said it would slash 20,000 jobs. CAT shares fell over 11% in premarket trading.
Meanwhile, MCD delivered what at first glance seems to be better-than-expected earnings of 87 cents vs. 84 cents. It even plans to invest $2.1 billion of capital to open about 1,000 new McDonald's restaurants.

American Express (NYSE: AXP) is the third Dow component tor report quarterly results after the close of trading today and is expected to report fourth-quarter earnings of 20 cents a share.

Tyson Foods, Inc. (NYSE: TSN) reported, according to this source, a decent quarter in terms of bottom-line profit, but it wasn't enough to satisfy Wall Street. Sales rose almost 10% to $7.2 billion. And net income on an adjusted basis came in at $0.15 per share. That represented pretty good growth over last year's profit figure. But you know, it didn't really matter for two reasons. One, the call by the analyst community was for four more pennies. Two, guidance was not tasty at all. Management sees further pressures coming, and the aforementioned source mentions that the fulfillment of debt obligations is an issue.

A tough environment for chicken has been plaguing Tyson. Not only that, but a look at the company's press release shows that operational cash flow took a huge dive over the last twelve months, dropping roughly 58% to $288 million. There was no free cash for the year to support the dividend obligations. That isn't too encouraging.

The bottom line on Tyson, which competes with the also-struggling Pilgrim's Pride (NYSE: PPC), is that it isn't a buy, at least not from where I sit. I know there will be investors out there who will see some value in the situation, but I cannot, at least not at this time. No, I'm not saying that I think Tyson will disappear. However, there are better ideas out there if you're looking to play the supermarket game over a long-term basis. There's Procter & Gamble (NYSE: PG), Kraft (NYSE: KFT), and Campbell Soup (NYSE: CPB), to name some examples. As I write this, Tyson's stock is down over 11%. Might we see a bounce in the next few days? Sure. But I'm not brave enough to step in with this one.
