Which one among the following products may have the highest bacterial counts?
  • Microbial Load Comparison in Dairy Commodities:
  • Raw Milk:
  • Fresh, unprocessed bovine milk directly from farm milking contains endogenous udder microflora, teat canal contaminants, and environmental dust/manure bacteria, easily yielding total viable counts of $10^5 - 10^7\text{ CFU/mL}$.
  • In contrast, Skim milk powder, Sweetened condensed milk, and Butter undergo pasteurization, thermal evaporation, and water-activity suppression, resulting in drastically lower microbial counts.
  • Conclusion: Raw Milk (Option 4).

Correct option: (4) Raw Milk
