Yet Another Food Recall

This time it's frozen pizza:

"CHICAGO (Reuters) - Almost five million Totino's and Jeno's frozen pizzas with pepperoni toppings are being recalled because the pepperoni may be contaminated with E. coli, General Mills Inc said on Thursday.

General Mills, which owns the Totino's and Jeno's brands, said the recall affects about 414,000 cases of pizza products currently in stores and all similar pizza products that might be in consumers' freezers. Each case contains 12 pizzas.

The possible E. coli contamination was uncovered by state and federal authorities investigating 21 E. coli-related illnesses in 10 states."

Are there more of these incidents because of a decline in quality and care from food manufacturers or is it because we have better capabilities to detect and investigate these things?
