WOTC - Food poisoning

I asked this question in the Wisdom of the Crowd:

Why do we have many food poisoning cases recently?

Here are the responses: (58 Votes)

52 % - We employ food handles from third world countries that are not hygenic.
31 % - The operators are not managing the preparation carefully.
12 % - These are temporary lapses.
5 % - The food supplies are contaminated.
