What structural feature on raw meat surfaces points specifically to bacterial colonization?
Answer
The development of a sticky or slimy film on the surface.
A sticky or slimy film developing on the surface of raw foods, particularly meats and poultry, is a distinct indicator linked to bacterial activity. This physical manifestation is identified as a biofilm, which is a complex structure comprised of microbial cells that have adhered to the surface and secreted an extracellular matrix. This film represents active bacterial growth and colonization. While this tactile cue often accompanies noticeable odors or discoloration, its presence alone is sufficient justification for discarding the meat due to the confirmed bacterial buildup.
