Consumer Reports Releases Study on Spices and Heavy Metals at Concerning Levels
Consumer Reports tested 126 products from 15 different categories of spices from Trader Joe’s, McCormick, Whole Foods, and other popular brands. Some were organic spices while others were not. Here’s some of the results that may be of interest to you:
| One-third of the tested products, 40 in total, had high enough levels of arsenic, lead, and cadmium combined, on average, to pose a health concern for children when regularly consumed in typical serving sizes. |
| Thyme and oregano — all results were concerning, so please consider growing them in your garden. |
|
31 products had levels of lead that were so high that they exceeded the maximum amount anyone should have in a day. |
| Both organic and conventional brands tested with high levels, so organic isn’t a predictor of safer food here. |
| 7 out of the 15 types of herbs and spices tested had heavy metal levels below the thresholds for concern. |
| None of the tested herbs and spices were contaminated with salmonella bacteria, which may cause foodborne illness. |
Heavy Metals Lead, Arsenic and Cadmium Can Be Dangerous to Your Health and Concerning in Spices
Frequent exposure to small amounts of heavy metals like lead, arsenic, and cadmium, can be hazardous to your health and can raise your blood lead levels. Consumer Reports found heavy metals in most categories of spices including basil, black pepper, chili powder, coriander, cumin, curry powder, garlic powder, ginger, paprika, saffron, sesame seeds, turmeric, and white pepper.
When the source of lead exposure is in the kitchen, it can increase a child’s risk of health problems. Heavy metals are difficult for the human body, especially children, to break down and excrete. Over time, they build up.
Heavy metals are particularly problematic to young children affecting brain development, increasing the risk of behavior problems, and a lowered IQ. When adults are exposed to concerning amounts of heavy metals it can increase reproductive problems, hypertension, decrease immune function. It’s also linked to kidney damage and central nervous system problems. Some recent studies have demonstrated concerning harm with heavy metals in spices:
- In 2018, a study in Morbidity and Mortality Weekly Report found high lead levels in 22% of food samples of mostly spices and herbal remedies from homes of children in North Carolina with lead poisoning. It seems that spices, depending on how high the levels are and how often they are used to cook with can have a significant effect on a child.
- In 2010, a study linked a case of lead poisoning in a baby boy from Massachusetts that was 12-months-old. The turmeric used by his family had high levels of heavy metals. In addition, there were 5 similar cases later discovered in Arizona, New York, California, Colorado, and Connecticut.
- Turmeric has been quite a problem since 2011. More than a dozen turmeric products have been recalled since that time.
- In terms of companies that are producing spices with high amounts of heavy metals, there are about two dozen spice companies from 11 countries subject to import alerts for lead contamination. When this happens, it’s a signal to regulators to detain and test those products.
Federal vs. California Prop. 65 “safe harbor” levels for heavy metals like lead and arsenic — So what levels of lead, arsenic, and cadmium are concerning to public health officials? According to the Food and Drug Administration, the levels inside your food that you are allowed to be exposed to are as follows:
• “Heavy metals as lead (as Pb), should not be in your food or supplements at more than 10 parts per million.
• Arsenic (as As), should not be in your food or supplement at more than 3 parts per million.
• Mercury (as Hg), should not be in your food or supplements at more than 1 part per million.”
When it comes to protecting consumers, California has far lower levels, but instead of banning products, they force manufacturers to use label warnings. If these Prop. 65 label warnings are inaccurate, companies can be sued by Californians.
California has stricter levels under their Prop. 65 List of Carcinogens for acceptable risk and No Significant Risk Levels (NSRLs) for cancer-causing chemicals and Maximum Allowable Dose Levels (MADLs) for chemicals causing reproductive toxicity. Any product that exhibits heavy metals above these amounts has to be labeled with a Prop. 65 warning to sell to Californians.
•Lead (as Pb), not more than 0.5 parts per million (ppm)
•Inorganic arsenic, not more than 10 ppb (except inhalation) inorganic arsenic
•Cadmium, not more than 4.1 ppb (oral)
Some brands have different product formulations made exclusively for California residents, so this does not mean that the California law covers everyone. But if you have ever seen a Prop. 65 warning label inside a package you purchased, it simply means they are just keeping things consistent with California standards across the United States.
Mamavation’s Recommended Brands Based on Heavy Metal Testing
Mamavation reviewed the consumer study from Consumer Reports testing 126 spices encompassing basil, black pepper, chili powder, coriander, cumin, curry powder, garlic powder, ginger, paprika, saffron, sesame seeds, turmeric, and white pepper. We divided the groups into three categories: “not our favorite,” “better” and “best.”
The levels are based on the levels of heavy metals like lead, cadmium, and arsenic that were detected by this independent study. Luckily, none of the tested herbs and spices were contaminated with salmonella bacteria, which can cause foodborne illness.
In order to help make this easier for you, we’ve recommended some products for you that passed and were also made from organic ingredients. We’ve linked up all the brands that passed in our “best” category separately.
