Who reads the food recalls?

I went to the health canada site listing the food recalls and alerts.
They had an ecoli alert on Oct 4 (general) and the Harveys in North B. was closed Oct 12. I guess they knew it was possible it was going to strike, but didn't know where? Oct 20,21,22,23 each day has new alerts about a new product with listeria. (non Maple leaf)
Now, the maple leaf thing was a big deal and probably hurt that company a lot. But when it happens with littler guys- no air time?
You don't want to panic, but being aware of the risks is good, especially when these things can make you very sick.
