Step 1: Identify the specific mold and its substrate.
The question asks about the effect of the mold {Thamnidium chaetocladioides} on meat.
Step 2: Recall the characteristic spoilage sign of this mold.
{Thamnidium} is known for its growth on refrigerated meat, particularly in large cuts stored for aging. It produces long, fuzzy mycelia that extend from the surface of the meat, a condition commonly referred to as "whiskers". This growth does not produce toxins and is often trimmed off before the meat is sold.
