"Would rubbing a slice of lemon on the peeled melon kill any transferred salmonella?"He doesn't address your question exactly, but Trevor Suslow at the University of California, Davis, put together a paper this week (posted yesterday, possibly motivated by the Honduran incident) that focuses on the home-cleaning issue:
Salmonella and Cantaloupe: What Can Consumers Really Do? (pdf)
Here's what he said about vinegar:
- White vinegar was better than brown.
- It takes quite a lot to be effective, so spraying a mixture of 1 cup white vinegar mixed with one cup tap water over the surface of the melon may be a best choice.
- Let set for at least 2 minutes, preferably 10 minutes, and then rinse.
I recall in my reading that organic acids, of the type you mentioned, weren't as effective. I thought they would be. I'll post if I find anything.
Are These Wash Steps Necessary?
"Unfortunately, we can’t truly answer this most reasonable question."
