This issue of raw (semi) product comes up once and a while and the black and
white answer is to prevent and prepare properly. When cooking the heck out of
something is not wanted there is an elememt of risk.

A good way of dealing with a specific recipe is to make sure your supplier has
a safe product to start with to the point of testing the odd sample, but
nothing is guaranteed always. Customers also must realize that there is a risk
from eating such product.

Freezing raw product can variably affect ptential pathogens negatively.

The big problem with food safety from pathogens is the so called garanteed
safe well cooked foods that come from fast food places where the elevated risk
inherent in a particular product demand good quality control in production
(all facets) is the  failure of a high risk proceedure failing probably due to
mechanical failure or human error.

The bottom line......there is an element of risk in eating any food but  one
is probably not going to die...loose a little weight maybe and tax the medical
system.

hope this helps some
