Which of the following describes US egg processing before market entry?

• A. Eggs are washed before entering the market.
• B. Eggs are never washed.
• C. Eggs are irradiated before market.
• D. Eggs are frozen before market.

Answer: (A)

In the United States, shell eggs sold to consumers are cleaned in processing plants before they enter the market. Washing and sanitizing the eggs remove dirt and reduce surface contamination, helping to ensure safety and extend shelf life. Because this washing step removes the natural protective bloom on the shell, the eggs must be refrigerated to slow any remaining bacterial growth and maintain quality. The other options don’t reflect standard US practice: eggs aren’t typically sold unwashed, irradiation isn’t a routine requirement for shell eggs, and freezing would damage the eggs and isn’t how shell eggs are marketed.
