We have yet another food product to add to the inflation list. This time it's cattle. Cattle futures on the Chicago Mercantile Exchange closed at an all-time high of $1.1752 per pound, as reported in the Wall Street Journal.

Beef is a in a special category. Unlike grains, which are harvested yearly, it takes about three years to raise cattle and bring them to market. High grain prices and high exports have shrunk the size of herds. They are at their lowest levels since the 1950s. With prices so high, some cattle ranchers choose to slaughter their cattle rather than let them mature to full term. These young cattle are called feeder cattle.

This post was part of AOL Money & Finance's Best & Worst of 2007 feature. Voting has now closed and readers have chosen rising fuel prices as the most worrisome consumer trend. Be sure to let us know in the comments if you are pleased with this result.

The most Worrisome Consumer Trend of 2007 is ... whichever one you choose. The following is my analysis of four candidates -- ranging from can't sleep at night to minor complaint:

• China product recalls. 30 million Chinese products -- many of them toys -- have been recalled in the last several months. With the holiday shopping season in full swing, this has to be among the most worrisome consumer trends. It's not easy to find out if a product is made in China. This list of U.S. made toys might help, and this list of Made in America products might also be useful.
• Subprime and mortgage meltdown. The cost to society of the subprime mortgage meltdown could be as high as $4 trillion. Two million people are expected to lose their homes to foreclosure by the end of 2008. If you are one of these people, this trend is definitely costing you sleep. And since there's no way of knowing how widespread the damage will be, everyone in the world should be worrying about this one.
