Perspective: The food risks consumers should worry about most

The Cyclospora outbreak highlights an important disconnect in public perceptions of food safety.

Consumers are bombarded with social-media videos warning about:

• Heavy metals in vegetables
• "Toxic" food additives
• Seed oils
• Plastic chemicals
• Trace pesticide residues

Some of these issues deserve scientific attention, especially for vulnerable populations or with long-term cumulative exposure.

But from a public-health standpoint, they generally are not what send people to emergency rooms this week.

The biggest risks are still microbes

Every year in the United States, foodborne pathogens such as:

• Salmonella
• Listeria
• E. coli O157:H7
• Campylobacter
• Norovirus
• Cyclospora

cause roughly:

• 48 million illnesses
• 128,000 hospitalizations
• About 3,000 deaths

according to longstanding CDC estimates.

These outbreaks can produce severe dehydration, kidney failure, miscarriage, bloodstream infections and death—particularly among young children, older adults, pregnant women and immunocompromised patients.

By comparison, many of the food hazards that dominate wellness influencers' feeds involve theoretical or long-term risks rather than immediate illness.

FDA retracts positive lettuce test, but Cyclospora outbreak investigation continues

The FDA now says a laboratory test that appeared to detect Cyclospora in Taylor Farms iceberg lettuce was a false positive, but the outbreak investigation is continuing and the recall remains in effect.

Relative risk matters

That doesn't mean concerns about contaminants or additives should be ignored.

But consumers often receive a distorted picture of food safety.

For example:

Higher immediate risk

• Undercooked poultry
• Contaminated leafy greens
• Raw sprouts
• Unpasteurized milk
• Cross-contamination in the kitchen

Generally lower immediate risk

• Trace heavy metals below regulatory limits
• FDA-approved food additives
• Approved pesticide residues
• Packaging chemicals at typical exposure levels

Public-health experts frequently note that consumers can reduce their risk far more by practicing safe food handling than by avoiding ingredients that become popular targets on social media.

The bottom line

The FDA's false-positive announcement changes one important detail of the Cyclospora investigation—but not the larger public-health message.

Thousands of Americans have already become ill in one of the largest produce-related outbreaks in years, and investigators continue searching for definitive laboratory confirmation of the source.

For consumers, the practical advice remains unchanged: follow recall notices, practice careful food handling, and remember that while wellness trends often focus on hypothetical chemical hazards, foodborne infections remain among the most common—and most preventable—serious risks in the American food supply.

Looking for advice?

It's not hard to find nutrition advice. The internet is crawling with it but much, if not most, of what you find there is bogus, promoted by the supplement manufacturers who sell unregulated, unproven nostrums of little or no value.

You can, of course, talk to your doctor but the truth is that many physicians are so busy that any advice you get from them will be at best sketchy. There are, of course, hundreds of reputable, science-based websites but it's hard consumers to know which are the most reliable.

Here's a hint: Anyone with "Ph.D., R.D." after their name is a registered dietitian who holds a doctoral degree. This is a person who actually understands nutrition down to the molecular level. A good example is Jessica Knurick, who posts regularly on Substack, Facebook and elsewhere. She offers accurate, science-based advice and also debunks the myths perpetrated by supplement pushers and their accomplices.
