Your Herbs and Spices Might Contain Arsenic, Cadmium, and Lead

Consumer Reports tested 126 products from McCormick, Trader Joe’s, Whole Foods, and other popular brands. Almost a third had heavy metal levels high enough to raise health concerns. There is no safe level of lead to have in the bloodstream and the effects of lead add up over time. Lead exposure has been linked to brain damage and developmental delays in children. All of the brands of oregano were determined to be of “some concern”. The Simply Organic brand appeared to be the cleanest of those tested.

In a separate article from Consumer Reports, the researchers found dangerous heavy metals in dark chocolate from Hershey’s, Theo, Trader Joe’s, and other popular brands.  Ghirardelli is popular brand that was listed as a safer choice. Read more at this link.

Excerpts from Consumer Reports:

Consumer Reports (CR) tested 126 products from McCormick, Trader Joe’s, Whole Foods, and other popular brands. Almost a third had heavy metal levels high enough to raise health concerns.

For two herbs, thyme and oregano, all the products we tested had levels that CR experts say are concerning.

In 31 products, levels of lead were so high that they exceeded the maximum amount anyone should have in a day, according to CR’s experts.

Also troubling: There was no single predictor of which products contained higher levels of heavy metals—for example, brand name didn’t matter, and neither did “organic” or “packed in USA” claims.

The good news? Many products performed well in the tests. In seven of the 15 types of herbs and spices tested, all the brands had heavy metal levels below our thresholds for concern. And in most others, we found at least one brand that fit into our No Concern category. And none of the tested herbs and spices were contaminated with salmonella bacteria, which may cause foodborne illness.

The Threat of Heavy Metals

Frequent exposure to even small amounts of lead, arsenic, cadmium, and other heavy metals is dangerous, in part because it’s difficult for the human body to break them down or excrete them. And over time, exposure to those heavy metals can harm health. In children, it can affect brain development, increasing the risk for behavioral problems and lower IQ. In adults, it can contribute to central nervous system problems, reproductive problems, and hypertension, and can damage kidney and immune function.

“Since the risks are serious,” Rogers says, “it pays to limit your intake of heavy metals as much as possible.”

Heavy metals can show up in food if the water or soil where food is grown contains them naturally or is contaminated because of pesticides or industrial uses, says Tunde Akinleye, a CR chemist who oversaw the testing. Heavy metals may also get into food, including herbs and spices, during manufacturing—from processing equipment or packaging, for example.

Laura Shumow, executive director of the American Spice Trade Association, says it’s almost impossible to rid herbs and spices of all heavy metals because of “the unavoidable presence in the environments where they are grown.” She also says the amount of heavy metals absorbed from the soil, and the part of the plant where they can end up, differs from plant to plant. The trade group offers companies guidance on how to limit contaminants that they can implement with their suppliers.

Shumow says that according to a recent risk analysis by the ASTA, spices make up less than 0.1 percent of dietary lead exposure in children ages 1 to 6. And even for adults, she says, the ASTA believes the risk is low “in large part because spices are a very small component of the diet.”

But CR’s data underscore a broader problem. “People reach for the herbs and spices in their kitchens multiple times a day,” Akinleye says. And for certain spices, just one serving—¾ teaspoon or more—per day leaves little room for heavy metal exposure from other sources. For example, CR’s previous testing found that some brands of fruit juice, baby food, and rice contain troubling amounts of heavy metals.

And smaller amounts of certain products could be a concern if they are combined with others in a recipe. For example, a dish that has just ¼ teaspoon each of Great Value (Walmart) Chili Powder, Trader Joe’s Organic Cumin, and La Flor Oregano per serving would contain enough arsenic, cadmium, and lead to pose a concern.

Other research also suggests that herbs and spices can contribute to heavy metal exposure. For instance, a 2018 study in Morbidity and Mortality Weekly Report found high lead levels in 22 percent of food samples—mostly spices and herbal remedies—taken from homes of children with lead poisoning in North Carolina.

And a 2010 study linked a case of lead poisoning in a 12-month-old Massachusetts boy in part to turmeric used by the family. Five similar cases were later discovered in Arizona, California, Colorado, Connecticut, and New York. And more than a dozen turmeric products have been recalled since 2011.

CR’s tests, however, demonstrate that it is possible for herb and spice companies to limit heavy metals in their products. “About two-thirds of the spices we tested did not have concerning levels of heavy metals,” Akinleye says. “So we know spices don’t have to have worrisome amounts of lead or arsenic or any other heavy metal.”

What’s In Your Water?

Groundbreaking Investigation Finds Alarming Levels of Arsenic, Lead and Toxic Chemicals in U.S. Tap Water

A joint investigation by the Guardian and Consumer Reports found drinking water samples from systems servicing more than 19 million people in the U.S. contained unsafe levels of multiple contaminants.

Millions of people face serious water quality problems in the U.S.

On Tuesday, the Guardian released the results of a nine-month investigation conducted jointly with Consumer Reports (CR) which showed alarming levels of heavy metals like arsenic, lead and chemicals from plastic PFAS (per- and polyfluoroalkyl substances) in drinking water samples across the U.S.

According to the Guardian, millions of people face serious water quality problems in the U.S. because of contamination, deteriorating infrastructure and inadequate treatment at water plants.

As part of the study, CR and the Guardian selected 120 volunteers to provide tap water samples which were then tested for heavy metals like lead and arsenic, contaminants and PFAS — a group of compounds found in hundreds of household products that are linked to learning delays in children, cancer and other health problems.

The samples came from water systems that service more than 19 million people.

Here are four key findings from this report:

  • A total of 118 of 120 samples analyzed had concerning levels of PFAS, arsenic or lead exceeding safety thresholds set by CR scientists and other health experts.
  • Almost every sample had measurable levels of PFAS and more than 35% of samples contained the potentially toxic “forever chemicals,” at levels that exceeded CR’s  maximum safety threshold.
  • About 8% of samples contained arsenic at levels above CR’s recommended maximum.
  • One tested water sample in New Britain, Connecticut, had a lead concentration of 31.2 ppb — more than double the U.S. Environmental Protection Agency’s (EPA) action level of 15 ppb, and 25 ppb higher than the water quality report sent to people who use the water.

In response to the findings, EPA spokesperson Andrea Drinkard said 93% of the population supplied by community water systems get water that meets “all health-based standards all of the time” and that the agency has set standards for more than 90 contaminants. That includes arsenic and lead but not PFAS.

However, according to an analysis of more than 140,000 public water systems published by the Guardian in February, millions of people in the U.S. are drinking water that fails to meet federal health standards, including limits for dangerous contaminants.

‘Forever chemicals’ (PFAS) in tap water

CR’s results showed PFAS in 117 of 120 samples tested, from locations across the country. Two CR samples had PFAS levels above the federal advisory level of 70 ppt, with the highest amount at 80.2 ppt.

PFAS chemicals have been manufactured and used in a variety of industries in the U.S. since the 1940s, according to the EPA. They can be found in food packaging, commercial household products, stain and water-repellent fabrics, nonstick cookware, polishes, waxes, paints, cleaning products, fire-fighting foams, oil and plastics industries and contaminated drinking water.

PFAS chemicals seep into water from factories, landfills and other sources. They’re often called “forever chemicals” because they can accumulate in the body and don’t easily break down in the environment.

An investigation into the health effects of PFAS involving research of 69,000 people revealed a “probable link” between exposure to a type of PFAS chemical and six health problems: high cholesterol, ulcerative colitis, thyroid disease, pregnancy-induced hypertension, and testicular and kidney cancers. Research has also linked PFAS to learning delays in children.

As reported by The Defender, science suggests links between PFAS exposure and a range of health consequences, including possible increased risks of cancer, thyroid disease, high cholesterol, liver damage, kidney disease, low birth-weight babies, immune suppression, ulcerative colitis and pregnancy-induced hypertension.

At least 2,337 communities in 49 states have drinking water known to be contaminated with PFAS, according to a January analysis by the Environmental Working Group, an advocacy organization.

Despite evidence of widespread contamination and health risks, the EPA has not set an enforceable legal limit for PFAS in drinking water. It has established only voluntary limits, which apply to just two forever chemicals — perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) — at 70 parts per trillion combined.

Harvard environmental health professor Philippe Grandjean has suggested that the limit should be just 1 ppt for PFOA and PFOS, citing his 2013 research published in Environmental Health.

Most municipalities don’t test for PFAS, and when they do, it’s only on a small scale.

Toxic arsenic in tap water

Almost every sample CR tested had measurable levels of arsenic, a common groundwater contaminant, including 10 samples with levels between 3 and 10 ppb, according to the Guardian.

CR scientists and environmental advocacy groups like the Natural Resources Defense Council (NRDC) have said the limit should be 3 ppb or lower, but the EPA allows arsenic in drinking water up to 10 ppb to balance the costs for water system operators against reducing health risks.

Research suggests exposure to minimal levels of arsenic can pose long-term health risks. A 2014 study in Environmental Health found that arsenic at 5ppb or greater was associated with reduced IQ in children.

As The Defender reported in March, arsenic was “ranked number one among substances present in the environment that pose the most significant potential threat to human health,” according to a congressional report that resulted from an investigation into heavy metals like lead and arsenic found in baby food.

According to the report: “Exposure to toxic heavy metals causes permanent decreases in IQ, diminished future economic productivity, and increased risk of future criminal and antisocial behavior in children. Toxic heavy metals endanger infant neurological development and long-term brain function.”

Dangerous level of lead in tap water

Concerns of lead in drinking water first made national headlines during the Flint, Michigan water crisis in 2015. Scientists and the EPA have agreed there is no safe exposure level for lead, though the EPA’s action level for lead is set at 15 ppb.

While New Britain’s annual water quality report for customers indicated that its average lead level was 6 ppb, one sample tested by CR showed lead concentrations of 31.2 ppb, more than double the EPA’s action level of 15 ppb.

Lead typically works its way into drinking water through lead pipes leading to peoples’ homes or in the homes’ plumbing. An estimated 3 to 6 million homes and businesses in the U.S. still get water through older lines that contain lead, according to EPA estimates, and an unknown number of homes have plumbing fixtures made of the heavy metal.

It is well established that inorganic arsenic and lead found in tap water are neurotoxic and can result in reduced IQ as well as adverse neurodevelopmental outcomes, such as autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD) — two conditions that have been steadily climbing for several decades, reported The Defender.

According to the Agency for Toxic Substances and Disease Registry, lead can also cause reproductive issues, low bone density, poor kidney function, cognitive decline and negatively impacts every organ system in the body. High levels of exposure can cause encephalopathy or death.

The American Academy of Pediatrics has identified no “threshold or safe level of lead in blood.”

Next steps — solving the problem

Although people can seek cleaner drinking water by using filters and home filtration systems that remove dangerous contaminates, CR says fixing the problem shouldn’t be up to consumers.

The NRDC has called on the Biden administration and Congress to enact legislation requiring the expeditious removal and replacement of lead lines and to take immediate steps to address PFAS contamination in drinking water.
