Ingredient in weedkillers tied to cancer is found in 80% of U.S. urine samples, new study finds

Scientists declare "disturbing" and "concerning" a new study's findings that 80% of urine samples drawn from U.S. children and adults contain a pesticide ingredient linked to cancer. 

The Centers for Disease Control (CDC) report, according to a recent story by Carey Gillam in The Guardian, says glyphosate, the active ingredient in herbicides (including Roundup, the world's best-selling weedkiller), was found in 1,875 samples out of 2,310 tested.

The samples were intended to be representative of the U.S. population, with almost a third of the participants being children between the ages of six and 18.

Professor Lianne Sheppard

Gillam's article quotes Lianne Sheppard, professor at the University of Washington's department of environmental and occupational health sciences, to the effect that she expects "the realization that most of us have glyphosate in our urine will be disturbing to many people."

Sheppard co-authored a 2019 analysis that found glyphosate exposure "increases the risk" of non-Hodgkin's lymphoma.

The amount of glyphosate in human urine, the Guardian story says as it cites research published by University of California San Diego School of Medicine scientists, "has been steadily rising since the1990s when Monsanto Co. introduced genetically altered crops [such as corn and soybeans] designed to be sprayed direction with Roundup."

In 2015, the International Agency for Research on Cancer, an arm of the World Health Organization, classified glyphosate as a probable human carcinogen.

The U.S. Environmental Protection Agency (EPA), however, claimed it was not likely to be that. Only last month, in contrast, a federal appeals court ruled the agency needs to give "further consideration" to the risks; that opinion also vacated the agency's safety determination. 

Dr. Philip J. Landrigan

Dr. Philip J. Landrigan, who worked at both the CDC and EPA for years and now directs Boston College's Program for Global Public Health and the Common Good, is also quoted by Gillam: "People of all ages should be concerned, but I'm particularly concerned for children. Children are more heavily exposed to pesticides than adult because pound-for-pound they drink more water, eat more food and breathe more air. Also, children have many years of future life when they can develop diseases with long incubation periods such as cancer. This is particularly a concern with the herbicide, glyphosate."

Vaccine can prevent most HPV cancers

Over one-fifth of U.S. adults are infected with cancer-causing virus, federal report says

More than 20 percent of U.S. grown-ups are infected with a cancer-causing virus, a federal agency has reported.

A story by Jia Naqvi in The Washington Post today says that a study by the Centers for Disease Control and Prevention showed almost 23 percent of American adults between the ages of 18 and 59 had one particular type "of genital human papilloma virus (HPV) that put them at high risk of certain cancers."

The percentage almost doubled — to 42 percent — "if any type of genital HPV was included."

Prevalence, the study of 2013 and 2014 showed, "was higher in men than in women, and it was sharply higher among blacks compared to other racial and ethnic groups."

Geraldine McQuillan

Geraldine McQuillan, lead author of the report and a senior infectious disease epidemiologist at the CDC's National Center for Health Statistics, is quoted as saying, "People really need to realize that this is a serious concern."

HPV is the most common sexually transmitted disease in the United States, the story states, with nearly 80 million people currently infected and about 14 million new infections occurring "annually among teenagers as well as adults."

Each year, the Post article adds, "31,000 men and women are diagnosed with cancers caused by HPV — which, in most cases, would have been preventable with the HPV vaccine, according to the CDC."
