Having spent over 20 years working on food-poisoning lawsuits, Bill Marler simply doesn’t eat certain foods anymore.

The attorney, who’s litigating suits against Chipotle after the chain’s E. coli and norovirus outbreaks, was cited in an article by Health Insider from BottomLine outlining what foods he’s cut from his diet.

Having won more than $600 million for clients in foodborne-illness cases, Marler says that his experiences convinced him that these foods aren’t worth the risks.

Here are the foods that scare this expert the most:

1.Raw oysters.
Marler says that he has seen more foodborne illnesses linked to shellfish in the past five years than in the two preceding decades. The culprit: warming waters. As global waters heat up, they produce microbial growth, which ends up in the raw oysters consumers are slurping down.

2. Precut or prewashed fruits and veggies.
Marler says that he avoids these “like the plague.” Convenience may be nice, but, as more people handling and processing the food means more chances for contamination, it isn’t worth the risk.

3. Raw sprouts.
Marler says that he avoids these “like the plague.” Convenience may be nice, but, as more people handling and processing the food means more chances for contamination, it isn’t worth the risk.

4. Rare meat.
Sorry, chefs: Marler isn’t going to order his steaks any rarer than medium-well. According to the expert, meat needs to be cooked to 160 degrees throughout to kill bacteria that could cause E. coli or salmonella.

5. Uncooked eggs.
For anyone who remembers the salmonella epidemic of the 1980s and early ’90s, this is a no-brainer. According to Marler, the chance of getting food poisoning from raw eggs is much lower today than it was 20 years ago, but he still isn’t taking any chances.

6. Unpasteurized milk and juices.
A growing movement is encouraging people to drink “raw” milk and juices, arguing that pasteurization depletes nutritional value. Marler says that pasteurization is not dangerous — but raw beverages can be, as skipping the safety step means an increased risk of contamination by bacteria, viruses, and parasites.

“There’s no benefit big enough to take away the risk of drinking products that can be made safe by pasteurization,” he says.
