In the 19th century, smallpox was widely considered a disease of filth, which meant that it was largely understood to be a disease of the poor. According to filth theory, any number of contagious diseases were caused by bad air that had been made foul by excrement or rot.

Filth theory was eventually replaced by germ theory, a superior understanding of the nature of contagion, but filth theory was not entirely wrong or useless.

The idea that “toxins,” rather than filth or germs, are the root cause of most maladies is a popular theory of disease among people like me. The toxins that concern us range from particle residue to high-fructose corn syrup, and particularly suspect substances include the bisphenol A lining our tin cans, the phthalates in our shampoos, and the chlorinated Tris in our couches and mattresses.

Many vaccines contain traces of the formaldehyde used to inactivate viruses, and this can be alarming to those of us who associate formaldehyde with dead frogs in glass jars. Large concentrations are indeed toxic, but formaldehyde is a product of our bodies, essential to our metabolism, and the amount of formaldehyde already circulating in our systems is considerably greater than the amount we receive through vaccination.

As for mercury, a child will almost certainly get more mercury exposure from her immediate environment than from vaccination. This is true, too, of the aluminum that is often used as an adjuvant in vaccines to intensify the immune response.

Our breast milk, it turns out, is as polluted as our environment at large. Laboratory analysis of breast milk has detected paint thinners, dry-cleaning fluids, flame retardants, pesticides, and rocket fuel. “Most of these chemicals are found in microscopic amounts,” the journalist Florence Williams notes, “but if human milk were sold at the local Piggly Wiggly, some stock would exceed federal food-safety levels for DDT residues and PCBs.”

fear of toxicity strikes me as an old anxiety with a new name. Where the word filth once suggested, with its moralist air, the evils of the flesh, the word toxic now condemns the chemical evils of our industrial world.

the way we think about toxicity bears some resemblance to the way we once thought about filth. Both theories allow their subscribers to maintain a sense of control over their own health by pursuing personal purity. For the filth theorist, this means a retreat into the home, where heavy curtains and shutters might seal out the smell of the poor and their problems. Our version of this shuttering is now achieved through the purchase of purified water, air purifiers, and food produced with the promise of purity.

Purity, especially bodily purity, is the seemingly innocent concept behind a number of the most sinister social actions of the past century.
