Correct. Lots of hot sauce, horseradish and beer helps cut the risk. I actually read that it is true a couple of years back in a posted article on the internet. Personally, you don't have enough horseradish in the cocktail sauce unless is stings your nose when you eat it.
In the words of Jimmy Buffett's song: "Give me oysters and beer, every day of the year and I'll be fine."
A dab of hot sauce (Crystals please) is good but not necessary. Just shuck em and suck em!
It's always worked for me!
