In the latest scare from the food industry, ConAgra has voluntarily halted production at the Missouri plant churning out Banquet pot pies. Health officials said that the pot pies could be linked to 139 cases of salmonella in 30 states. The largest number of cases have been reported in Wisconsin, Pennsylvania, and Missouri. So far, no deaths have been linked to the pot pies.

The Omaha-based food company says its pies should be safe if cooked properly, but still advises against eating chicken or turkey-based pies until investigations by the government and by CAG officials are complete.

ConAgra is offering refunds for these pot pies, but a recall of existing products has not yet been planned.

CAG has been shuffling sideways for about a year and is currently slamming into its 20-month moving average. If this trendline is violated, it could portend downside for the shares, or could accelerate a bearish cross of the stock's 10-month and 20-month moving averages. In early trading, the stock is down about half a percent.
