Consuming raw cookie dough poses the greatest risk of

While consuming raw cookie dough may cause indigestion due to its high sugar and fat content, it is not considered the greatest risk. Indigestion is typically a mild and temporary condition, while a Salmonella infection can be severe and even life-threatening in some cases.

Trichinellosis is an infection caused by the roundworm Trichinella. It is typically associated with consuming undercooked or raw meat, particularly pork or wild game, not cookie dough. While it's possible for other food items to be cross-contaminated, it's unlikely that consuming raw cookie dough would lead to Trichinellosis.

E. coli infections are typically associated with consuming contaminated vegetables or undercooked ground beef, not raw cookie dough. However, flour, a main ingredient in cookie dough, can sometimes be contaminated with E. coli. Despite this, the risk of E. coli infection from raw cookie dough is lower than the risk of a Salmonella infection due to the common use of raw eggs in cookie dough.
