All meats handled under less than sanitary conditions have risks. Fruits and vegetables ditto.

Two recent recalls involving Listeria contamination of sausage. Sausage and duck recalled in June in New York. Imported Dutch sausage contaminated with Chinese chemicals, etc., etc.

In the old days, meats were often heavily spiced (peppered, whatever) to cover up decomposition, but that was more cosmetic than preventive.

As emphasized above more than once, a local source that is fresh and that you know something about is safest; also follow safe cooking and cleaning recommendations.
