Food Science and Technology QUESTION #5931
Question 1
Somatic cell count (SCC) in milk is used as an indicator of:
  • Antibiotic contamination
  • Fat content variation
  • Udder health — elevated SCC (\(>200{,}000\text{–}400{,}000\;\text{cells/mL}\)) indicates mastitis✔️
  • Bacterial contamination from the environment
Correct Answer Explanation
SCC measures white blood cells and mammary epithelial cells shed into milk. Normal SCC \(< 200{,}000\;\text{cells/mL}\); SCC \(> 400{,}000\;\text{cells/mL}\) (EU limit) indicates subclinical mastitis, which reduces milk quality (lower casein, higher plasmin, reduced shelf life).
