Bill Marler, an expert on food poisoning, has cut some foods out of his diet after spending more than two decades as a foodborne-illness attorney.
Here are eight foods that anyone trying to avoid food poisoning should cut from their diet.
Meghan Markle is preparing to follow in the footsteps of Queen Elizabeth II as the royal wedding date nears — and that includes culinary traditions.
The Sun reports that a "weird rule prevents the queen and other royals from eating foods like mussels and rare steak when dining out."
"They're advised to steer clear of foods which could cause food poisoning, like shellfish, rare meat, and tap water when they're abroad," the report says.
It's a sensible tradition — no one wants to be forced to alert the public that they need to miss a royal function because they have contracted food poisoning from slurping down raw oysters.
According to The Sun, the queen closely follows the rule, while other members of the royal family take a more lenient approach.
Bill Marler, an expert on food poisoning who has previously spoken with Business Insider, follows a similarly strict diet. He has won more than $600 million for clients in foodborne-illness cases and has become convinced that some foods aren't worth the risk.
Here are the foods that Marler says anyone trying to avoid food poisoning should avoid.
Marler told Business Insider that the idea that he would have to warn people against drinking unfiltered, untreated water didn't cross his mind until this year.
"Almost everything conceivable that can make you sick can be found in water," Marler said.
So-called raw water — even from the cleanest streams — can contain animal feces, spreading giardia, an intestinal infection that includes symptoms such as vomiting and diarrhea and results in roughly 4,600 hospitalizations a year.
E. coli, cholera, and hepatitis A, which led to 20 deaths last year in an outbreak in California, can also be spread through untreated water.
