A few weeks ago,  the FDA announced  volunary recalls of  3 brands of baby pouches containing apple sauce with cinnamon, because they contained excess lead.

Lead is poisonous to children’s nervous systems and brain development; there is no safe level of lead intake.

DO NOT LET YOUR KIDS EAT THESE PRODUCTS!

The FDA inspected the plant in Ecuador where cinnamon apple sauce is made; the amounts of lead were shockingly high.  Food Safety News reports:

The applesauce, sold in pouches packaged for children, has been found to have a lead content of 5110 parts per million (ppm) and 2270 ppm. The international Codex body is considering adopting a maximum level of 2.5 ppm for lead in bark spices, including cinnamon.

What is even more shocking about this situation is how the FDA found out about the lead—not by testing but because

…a developing investigation by the North Carolina Department of Health and Human Services and the North Carolina Department of Agriculture & Consumer Services [found] about four children with elevated blood lead levels, indicating potential acute lead toxicity.

The state investigation identified WanaBana apple cinnamon fruit puree pouches as a potential shared source of exposure. As part of their investigation, the department of health and human services analyzed multiple lots of WanaBana apple cinnamon fruit puree, detecting extremely high concentrations of lead.

The FDA then announced it was investigating cinnamon as a source of the lead.

It traced the cinnamon to a supplier in Ecuador.

The FDA suspects that somewhere along the supply chain, someone deliberately added lead to the cinnamon to maintain its color and increase its weight.

This reminds me of the addition of Chinese melamine to pet food and infant formula in 2006 and 2007 (I wrote about the pet food scandal in Pet Food Politics: The Chihuahua in the Coal Mine).

This also points to the need for strengthening the FDA.  It is not required to test products for lead and neither are manufacturers.

The FDA has proposed action levels for lead in foods, but these are neither final nor implemented.

The New York Times quoted Tom Neltner, safety expert at the Environmental Defense Fund:

That the levels of lead in children’s blood tends to be the first line of detection for lead in food is “effectively using kids as canaries…What this shows is a breakdown in the agency, and an industry that needs to be fixed.”

By industry, I’m assuming he means baby food and I could not agree more.

Pouches may be convenient for parents, but they promote sweet tastes and don’t teach kids how to eat real foods.  One study concluded:

Squeeze pouch products available in Australia are nutritionally poor, high in sugars, not fortified with iron, and there is a clear risk of harm tothe health of infant and young children if these products are fed regularly. The marketing messages and labelling on squeeze pouches are misleading and do not support WHO or Australian NHMRC recommendations for breastfeeding or appropriate introduction of complementary foods and labelling of products. There is an urgent need for improved regulation of product composition, serving sizes and labelling to protect infants and young children aged 0–36 months and better inform parents.

That goes for U.S. products too.

Caveat emptor.

The House Oversight Subcommittee has just issued another report on neurotoxic heavy metals—arsenic, lead, cadmium—in baby foods: New Disclosures Show Dangerous Levels of Toxic Heavy Metals in Even More Baby Foods.

Food and Drug Administration (FDA)-funded testing conducted by the State of Alaska found that multiple samples of Beech-Nut’s and Gerber’s infant rice cereals contained more inorganic arsenic than FDA’s 100 parts per billion (ppb) limit (an  already dangerously-high standard that FDA is now lowering). Beech-Nut issued a recall but limited it to product codes associated with only two of the six samples that Alaska’s testing found contained over 100 ppb. Its recall was therefore too narrow. Gerber failed
to recall product associated with either of its two infant rice cereal samples that tested over 100 ppb.

The FDA, it says is not doing enough—it is absent without leave-–on this issue.

This subcommittee issued its first report on this issue in February this year.  Then, the press release included a statement from Subcommittee Chairman Rep. Raja Krishnamoorthi:

Baby food manufacturers hold a special position of public trust.  But consumers mistakenly believe that these companies would not sell unsafe products.  The Subcommittee’s staff report found that these manufacturers knowingly sell baby food containing high levels of toxic heavy metals.  I hope companies will commit to making safer baby foods.  Regardless, it’s time that we develop much better standards for the sake of future generations.

This new report says baby food manufacturers aren’t doing enough, and neither is the FDA.  The subcommittee recommends:

To the FDA:

• Issue Maximum Toxic Heavy Metal Levels Sooner
• Mandate Finished-Product Testing

To Industry:

• Adopt Finished-Product Testing
• Voluntarily Phase Out Toxic Ingredients

Really?  That’s the best they can do?

This is either a serious problem or it is not.

If they think it’s serious (it sure sounds serious to me), more immediate and tougher actions are needed.  Now!

This has gone on long enough.

I’ve been posting about this issue since 2018.  This year, it looked like the FDA was going to take firm action, but no such luck.  Maybe this congressional subcommittee will get some action at long last.

• October 3, 2018  Rice cereals for infants: the arsenic problem
• February 9, 2021  Uh oh. Baby foods contain toxic metals—arsenic, lead, cadmium, mercury
• March 9, 2021  More on toxic metals in baby foods: FDA on the job!
• May 4, 2021 What is the FDA doing about heavy metals in baby food?

In the latest episode in the ongoing saga of high levels of arsenic in rice cereal marketed to babies, Beech-Nut says it is going out of the rice cereal business.

In addition to issuing the voluntary recall, Beech-Nut has also decided to exit the market for Beech-Nut branded Single Grain Rice Cereal. Beech-Nut is concerned about the ability to consistently obtain rice flour well-below the FDA guidance level and Beech-Nut specifications for naturally occurring inorganic arsenic.

Background: I have been posting about arsenic in rice since 2013.  In 2015, I wrote about how

• Rice cereals contain higher-than-desirable levels of arsenic.
• Arsenic gets into rice from natural sources but also from arsenic pesticides.
• The FDA says these levels do not pose health problems.
• Consumer Reports recommends not feeding rice cereals to children.
• The U.S. Rice Federation said the CR recommendation was not supported by science.

In August 2020, the FDA finally set guidelines for upper limits of arsenic in baby foods.  I wrote most recently—in May this year—about pressures on the FDA to set and enforce more rigorous standards and to go beyond its “Closer to Zero” plan to reduce heavy metals in baby foods.

Now the FDA announces the recall of Beech-Nut rice cereal with levels of arsenic that exceed those standards.

The Environmental Working Group asks if you should worry about arsenic in rice.  Its answer: Yes.

Rice, it points out, is a “specifically risky crop. Eating less rice and foods with rice-based ingredients will decrease the amount of arsenic in your body.”

EWG also recommends government actions:

• Crop monitoring programs
• Soil testing
• Elimination of use of sewage sludge as fertilizer (this practice is forbidden in organic foods)
• Clear communication of risks

At long last, pressures to fix this problem are having an effect.

Lawsuits also might help, as indicated by this item.

Heavy metals in baby food: 86 lawsuits and counting as Beech-Nut decides to exit infant rice cereal category owing to inorganic arsenic concerns:  At least 86 lawsuits have now been filed against firms named in the recent Congressional Subcommittee report on heavy metals in baby food including Beech-Nut Nutrition, which has just announced plans to exit the infant rice cereal category citing difficulties in sourcing rice flour that is consistently below FDA guidance levels for inorganic arsenic….

An article in Food Navigator—Asia got my attention:  “A study by researchers from Saudi Arabia, Egypt and China has found that the levels of iron, chromium, cadmium and nickel in fish caught from the Red Sea exceeded the levels recommended by various authorities such as the EU, FAO, and WHO.”

Heavy metals are not just in baby foods (see post from a couple of days ago).

Now they are a problem in Red Sea fish.

This is no surprise.  Recall the enormous effort needed to  extract the 1300-foot container ship, Ever Given, from the banks of the Suez Canal.

Hundreds of ships going through the Red Sea and the Canal every week, all of them dumping waste water.

An article in the Saudi Journal of Biological Sciences observes that the Red Sea environment is heavily contaminated with heavy metals; these accumulate in fish muscles.

The concentrations of Cr, Fe, Ni and Cd, analyzed in this study were higher than other heavy metals due to the overloading of industrial waste and the disposal of the water from Jeddah. Mn, Cu, and Pb concentrations, however, were far below the levels recommended by various authorities…It was concluded that the fishes captured from Jeddah Coast, Red Sea, are still safe for human consumption, but the amount consumed should be controlled under the FAO/WHO guidelines.

So–it’s up to you to protect yourself from contaminated fish.

How about international shipping policies that restrict what ships can dump into international waters?

I’ve written previously about the alarming findings of toxic heavy metals in baby foods.  These toxins are in all foods, but are particularly harmful to infants and young children, a situation that calls for immediate FDA action to set limits on the amounts these foods contain.

The FDA has a Q and A on this issue.  It has also issued previous guidance.

• Metals and Your Food
• What FDA is Doing to Protect Consumers from Toxic Metals in Foods
• What You Can Do to Limit Exposure to Arsenic
• Arsenic in Food and Dietary Supplements
• FDA Makes Available Results from Testing of Infant Rice Cereal for Inorganic Arsenic

In response to many complaints, the FDA has now issued a plan for action:  “Closer to Zero.”

Translation: the agency will propose action levels (limits on allowable amounts), consult with stakeholders, finalize the limits, and then evaluate how the whole thing works to reduce intake levels.

Timeline: It plans to do this starting now, with the aim of finishing the process by 2025.

The FDA must not consider limiting toxic metals in baby food to be urgent.

No wonder some members of Congress have introduced la bill to force the FDA to set limits for the most common toxic metals within a year.  It suggests what those limits should be: 10 parts per billion for inorganic arsenic in baby food (15 ppb for cereal); 5 ppb for both cadmium and lead (10 ppb for cereal); and 2 ppb for mercury.

While all this is going on, what are parents to do?

Suggestions from Harvard Health

The FDA is working on doing better monitoring and regulation of heavy metals in commercial baby foods. In the meantime, it’s nearly impossible to know which are completely safe and which aren’t. Babies don’t need solid foods until 6 months of age. At that time it’s perfectly fine to give them soft table foods instead of baby foods. You can also make your own baby food, using steamed or naturally soft foods and a blender. (Storage tip: you can pour a homemade puree into an ice cube tray and freeze it, and then just grab the cubes you need each time.)

Suggestions from Healthy Children

• Give your child a wide variety of different foods (the more natural colors, the better).
• Vary the grains. As mentioned above, it’s best to limit rice and rice products (check labels — rice is in a lot of foods marketed for babies, like “puffs”). Try barley, oats, and other grains. When cooking rice, it’s best to cook it in extra water and drain that water off, and to use white basmati and sushi rice, which have less arsenic.
• Check your water. Old pipes can contain lead, which can leach into drinking water.
• Avoid fruit juices. Not only can they increase the risk of cavities and obesity, but many commercial juices also contain heavy metals.
• Make healthy fish choices. Fish contains nutrients that are very healthy for the developing brain, but some fish can contain unhealthy amounts of mercury. Stay clear of big, predatory, long-living fish like swordfish, shark, or albacore tuna; it’s better to choose fish like cod, light tuna, salmon, or pollock.

In the meantime…

• The lawsuits!  At least 69 had been filed as of April 29.
• The New York Attorney General is also looking into this.

I am often asked about the potential dangers of arsenic in rice.  As with all such questions, I start with the FDA.

The FDA says the amounts of arsenic it finds in foods do not pose a risk at current levels of consumption.  Brown rice, it finds, has levels of arsenic much higher than those in white rice.

Consumer Reports also tested rice samples.  It recommends against feeding rice cereals to children.  It calls on the FDA to set standards for arsenic levels in rice products.  These, according to the tests, vary widely.  Basmati rice from California, India and Pakistan and U.S.-grown sushi rice are “better choices.”  Just one serving of rice cereal or rice pasta could put a child over CR’s recommended weekly limit

On this basis, Congresswoman Rosa DeLauro (D-CT) introduced legislation— The R.I.C.E (Reducing food-based Inorganic Compounds Exposure) Act— to limit the amount of inorganic arsenic, the most toxic form of arsenic in rice foods.  The act would require the FDA to set limits on arsenic in rice.

Politico reported that the US Rice Federation questioned the science behind the Consumer Reports story:

Arsenic in our food supply is a challenging, yet unavoidable, situation which is why we support the FDA studying the issue carefully,” said Betsy Ward, president and CEO of the USA Rice Federation.  “But CR’s new consumption recommendations aren’t supported by any science that we’ve seen.”

How does arsenic get into rice?  Lots of ways, apparently: naturally occurring, but also from arsenic pesticides that persist in soil.  The flooding makes rice especially susceptible.

What to do while waiting for a resolution to safety questions?  Prepare rice in a coffee percolator says a recent study.  This flushes out a lot of the arsenic.

And everything in moderation, of course.

Yesterday’s New York Times contained this remarkable news item from the Associated Press, reproduced here in its entirety (thanks to Maya Joseph for making sure I didn’t miss it):

Contaminated traditional beer has killed 56 people in Mozambique, health officials said Sunday. In addition, 49 people were admitted to hospitals in the Chitima and Songo districts in Tete Province, and 146 people have been examined for signs of the poisoning, a district health official, Alex Albertini, told Radio Mozambique. Those who drank the contaminated brew were attending a funeral in the region on Saturday, Mr. Albertini said. The authorities said they believed that the drink was poisoned with crocodile bile during the course of the funeral. The woman who brewed the beer is also among the dead.

A little checking around brought me to The Guardian, which explained:

When a crocodile is killed, its gallbladder must be immediately removed and buried in front of witnesses to stopped the bile being used as a poison, according to some African traditions.

But wait!

David Kroll writing in Forbes questions the accuracy of this report.  He did some homework and found an 1980s article from an African medical journal written by professor N.Z. Nyazema, a clinical pharmocologist at the University of Zimbabwe (whom Kroll is trying to track down).  Professor Nyazema says:

It is widely believed that the bile from the gall bladder of a crocodile is very poisonous. The bilenduru is used as poison which is added to beer or stiff porridge, sadza, of an unsuspecting victim. It is not easy to buy this poison neither is it easy for anyone to kill a crocodile solely for the purpose of obtaining the bile. But with a good fee one can obtain some of the poison from a special n’anga [a traditional healer of the Zimbabwean Shona tribe]…It is reported that the poisoning occurs at special occasions like beer drinking: The nduru is said to be introduced into the beer by dipping the finger or nail where a small amount is placed: This will suffice for the purpose.

Kroll sensibly asks: “In the current tragedy in Mozambique, I can’t imagine just how much bile would’ve had to be added to 210 liters of brew for so many deaths to occur.”

Good point.  He suspects digitalis from foxglove.

I’m crossing this one off my list of food ingredients to worry about.  Whew.

The food and chemical industries are lobbying hard against what is expected to be a tough report from the Environmental Protection Agency (EPA).

The report will set an upper limit for safe consumption of dioxins.

Most Americans consume dioxins at levels higher than this standard, mostly from food.

About 90% of dioxins come from foods, particularly high-fat animal foods.

Dioxins mainly enter the food chain as by-products of industrial processes.  To a lesser extent, they also come from natural processes such as volcanoes and forest fires.  They contaminate land and sea, are consumed in feed, move up the food chain, and end up in the fatty parts of meat, dairy products, and seafood.

Dioxins accumulate in fatty tissues.  They increase the risk of human cancer more than any other industrial chemical.

The EPA is expected to recommend an intake limit of 0.7 picograms of dioxin per kilogram body weight per day.  A picogram is one trillionth of a gram.  The World Health Organization and European Union limit is higher—from 1 to 4 picograms per kilogram per day.

The food and chemical industries argue that the proposed EPA limit is too low.

The EPA thinks less is better.  Dioxins are toxic and Americans typically consume amounts within the European range.   A single hot dog can contain more dioxin than the proposed limit for a 2-year-old.

Dioxin levels in the United States have been declining for the last 30 years due to reductions in man-made sources. But they break down slowly and persist for a long time in the environment.

How to avoid them?  The best way is to eat less high-fat meats, dairy foods, and seafood.

No wonder the food industry is alarmed.

A “Food Industry Dioxin Working Group” of trade associations such as the International Dairy Foods Association, the American Frozen Food Institute, and the National Chicken Council wrote to the White House:

Under EPA’s proposal…nearly every American – particularly young children – could easily exceed the daily RfD [reference dose] after consuming a single meal or heavy snack…The implications of this action are chilling.

Since the agency contends the primary route of human exposure to dioxin is through food, this could not only mislead and frighten consumers about the safety of their diets, but could have a significant negative economic impact on all US food producers.

These groups singled out the media for particular blame:

The media will inevitably report on this change and in all likelihood misinterpret the RFD as a ‘safe limit’. As a result, consumers may try to avoid any foods ‘identified’ as containing or likely to contain any dioxin.

Eat more fruits and vegetables anyone?

Congressman Ed Markey (Dem-MA) is urging the EPA to get busy and release its report:

The American public has been waiting for the completion of this dioxin study since 1985 and cannot afford any further delays…A baby born on the day the EPA completed its first draft health assessment would be 27 years old today. I’d like to see the final EPA analysis before it turns 28.

Let’s hope the EPA does not cave in to industry pressure and releases the report this month as promised.

Technical note:

“Dioxins” collectively refers to hundreds of chemical compounds that share certain structures and biological characteristics. They fall into three closely related groups: the chlorinated dibenzo-p-dioxins (CDDs), chlorinated dibenzofurans (CDFs) and certain polychlorinated biphenyls (PCBs). The most studied is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD).  PCBs are no longer produced in the U.S.
