Pesticides Linked to a Painful Autoimmune Skin Disease

People exposed to pesticides are more likely to develop pemphigus vulgaris, an autoimmune disease where your immune system attacks your own skin and mucous membranes, causing painful blisters that don't heal easily.

What the Study Found

A 2026 case-control study in Clinical and Experimental Dermatology conducted in Liguria, Italy, compared people with autoimmune bullous diseases to healthy controls. The researchers found that pesticide exposure was a risk factor for pemphigus vulgaris (PV).

PV is rare but devastating. It causes blisters on the skin and inside the mouth, throat, and other mucous membranes. Without treatment, it can be life-threatening. And now there's evidence that the pesticides on your lawn or in your food supply could be triggering it.

Who's at Risk

Anyone exposed to pesticides regularly: farmers, landscapers, gardeners, and people living near agricultural areas. But you don't have to work on a farm. Pesticide residues on produce, lawn treatments, and household bug sprays all count as exposure.

What You Can Do

Go organic when you can, especially for produce on the "dirty dozen" list. Stop spraying pesticides on your lawn. Use natural pest control methods. If you're a gardener, wear gloves and wash your hands thoroughly after handling any treated soil or plants.
