The Cookie Dough mystery deepens

I’m in Alaska this week and out of Internet contact most of the time so it’s been hard to follow the cookie dough story.  It seems that the strain of E. coli found in the cookie dough does not match the strains in the people who have gotten ill from (presumably) eating it.  The FDA can’t figure out how E. coli got into the cookie dough.

When I can get to a computer, I like to check the FDA page on this outbreak, and also the one from the CDC.  But it looks like they are only updating the pages about once a week.  So the quickest way to keep current on this is through Bill Marler’s blog.

E. coli found in cookie dough

The story thus far:

From January to June 2009, at least 69 people from 29 states have gotten sick with E. coli O157:H7.  Many of them confessed to eating Nestlé’s raw cookie dough.

On June 19, the FDA warned the public not to eat Nestlé’s raw cookie dough.  Nestlé issued a “voluntary’ recall.

Everyone is baffled about how E. coli O157:H7 could have gotten into cookie dough.  They wonder if cookie dough really is the cause.

The voluntary recall isn’t working (most don’t).  Obama Foodorama has no trouble finding plenty of recalled cookie dough on Washington DC shelves.

The Wall Street Journal reports that since 2006, Nestlé has consistently refused to allow FDA investigators to look at their safety records.  The company doesn’t have to.  All those pesky regulatory requirements are voluntary (that word again).

But now, in a spirit of someone more enforced cooperation, Nestlé lets the FDA in.  Bingo.  On June 29, the FDA says it finds E. coli O157:H7 in one batch of cookie dough.    But conversations with FDA officials leave many questions unanswered.

Nestlé is understandably concerned.   The company says it “deeply regrets” what happened and is fully cooperating with the FDA.

OK.  So if we didn’t know it before, we know it now: “voluntary” is a euphemism for not having to do anything.  Doesn’t this suggest the need for some real regulations?

At last: some clear thinking about cookie dough

OK, so Bill Marler is a class action lawyer* who makes his living from suing companies that produce unsafe food. I’ll grant that he has a vested interest but I admire the way he never loses sight of the harm done to innocent adults and children.  Cookie dough has a warning label on the package and everyone knows you are not supposed to eat raw cookie dough.  If you eat it, it’s your fault if you get sick, right?  See what he has to say about that one.

In Marler’s view, the warning label on commercial raw cookie dough should read something like this:

THE FDA INSPECTION MEANS NOTHING. THIS PRODUCT MAY CONTAIN A PATHOGENIC BACTERIA THAT CAN SEVERELY SICKEN OR KILL YOU AND/OR YOUR CHILD. HANDLE THIS PRODUCT WITH EXTREME CARE.

And, he asks, “Where is the multi-million dollar ad campaign to convince us of the dangers of uncooked cookie dough, like we do for tobacco?”

I would add a few further questions: What are we going to have to do to get a real food safety system in this country?  By real food safety system, I mean one that requires production of all foods – from farm to table – under science-based food safety plans (HACCP with pathogen reduction), overseen by a single federal agency that unites and rationalizes the current functions of USDA and FDA.

Everyone knows how to produce food safely or a lot more safely than is being done now.  If companies don’t bother, it’s because they don’t have to. You don’t like this?  Complain to Congress!

*Correction: See Mr. Marler’s comment below.  He says he mostly represents individuals.   I do apologize for the error.

How could E. coli O157:H7 get into cookie dough?

Thanks to Bill Marler for discussing this question on his blog this morning and for suggesting starting with the ingredient list.  As a typical example, here is the ingredient list for Nestlé’s Chocolate Chunk cookie dough (others can be found at this site):

INGREDIENTS: BLEACHED ENRICHED FLOUR (WHEAT FLOUR, NIACIN, REDUCED IRON, THIAMIN MONONITRATE, RIBOFLAVIN, FOLIC ACID), SUGAR, NESTLE SEMI-SWEET CHOCOLATE CHUNKS (SEMI-SWEET CHOCOLATE [SUGAR, CHOCOLATE, COCOA BUTTER, MILKFAT, SOY LECITHIN, VANILLIN – AN ARTIFICIAL FLAVOR, NATURAL FLAVOR]), MARGARINE (PALM OIL, WATER, SUNFLOWER OIL, HYDROGENATED COTTONSEED OIL, SALT, VEGETABLE MONO- AND DIGLYCERIDES, SOY LECITHIN, SODIUM BENZOATE, CITRIC ACID, NATURAL AND ARTIFICIAL FLAVOR, BETA CAROTENE COLOR, VITAMIN A PALMITATE ADDED), WATER, CORN SYRUP SOLIDS, MOLASSES, EGGS, EGG YOLKS, BAKING SODA, SALT, CORNSTARCH, SODIUM ALUMINUM PHOSPHATE, VANILLA EXTRACT, VANILLIN – AN ARTIFICIAL FLAVOR

MADE ON EQUIPMENT THAT ALSO PROCESSES PEANUTS/NUTS

CONTAINS: MILK, EGG, SOY, WHEAT INGREDIENTS

For starters, we don’t really know yet whether raw cookie dough is the source of this E. coli outbreak.  It could be something else, and Nestlé will have recalled 300,000 cases purely out of precaution.  The most likely source of bacterial contamination is eggs, but eggs typically carry Salmonella, not E. coli O157:H7.   And besides, the eggs in raw cookie dough are undoubtedly pasteurized, which ought to kill any bacteria that happen to be present.

The usual source of this toxic form of E. coli is cow manure.  Cows that carry this bug do not necessarily become ill, but they excrete it. Recall the spinach E. coli outbreak in 2006?  The spinach field was one mile away from a cattle crossing over a stream.  California investigators identified the particular strain of E. coli that caused the problem in cattle, cattle feces, and water at the cattle crossing, but did not found it in the field.

All they could do is speculate. Their leading hypotheses were runoff, a change in the water table, and (my favorite) wild boar.  Unfortunately for this last theory, when they surveyed wild boar for E. coli O157:H7, they found fewer than 0.5% to carry it.  So how E. coli got into the spinach remains a mystery.

As for the cookie dough, I’m guessing that everyone involved is having a busy weekend testing the ingredients, the packing plants, and everything else they can think of.  Let’s hope they find the source right away.

Cookie dough alert: E. coli O157:H7

As a result of investigations in Colorado, the FDA has just issued one of it’s lovely warnings of “voluntary” recalls, this time of Nestlé ‘s raw Toll House cookie dough (see product list).

I’d like to know if cookie dough is really the problem.  If there is a problem with cookie dough, it’s usually Salmonella. If cookie dough is the culprit, how on earth did this nasty form of E. coli, usually excreted by farm animals, get into it?  Eggs?  Butter?  Chocolate?  Flour?   In the meantime, the tally has reached 65 victims in 29 states: 25 hospitalizations, 7 with severe complications, no deaths.  Here’s the brand new CDC Nestlé Toll House Cookie Dough outbreak page with the statistics.

The roster: spinach 2006, pet food 2007, tomatoes (or was it jalapeno peppers or cilantro) 2008, peanut butter 2009, pistachios 2009. And now cookie dough.

The endless mantra is that we need prevention: HACCP, pathogen testing, and independent third-party verification.

Ben & Jerry’s top flavors: in order of calories???

Ben & Jerry’s is now owned by Unilever.

Here are its top-ten best-selling flavors:

  1. Half Baked: unbaked cookie dough and baked fudge brownies.
  2. Cherry Garcia: in the top three since its launch in 1987
  3. Chocolate Chip Cookie Dough
  4. Chocolate Fudge Brownie: this contains brownies from New York’s Greyston Bakery, which provides jobs and training to low-income people in Yonkers
  5. Tonight Dough: Jimmy Fallon’s second flavor; proceeds to SeriousFun Children’s Network
  6. Strawberry Cheesecake
  7. Phish Food: since 1997
  8. Americone Dream: a partnership with Stephen Colbert, whose staff chooses the nonprofit its proceeds go to
  9. Chunky Monkey: banana ice cream with fudge chunks and walnuts
  10. Brownie Batter Core

Whether or not proceeds go to charity, these are commercial ice creams, and highly caloric, ultra-processed ones at that.

Here, for example, is the ingredient list for a Cherry Garcia.

CREAM, SKIM MILK, LIQUID SUGAR (SUGAR, WATER), WATER, CHERRIES, SUGAR, EGG YOLKS, COCONUT OIL, COCOA (PROCESSED WITH ALKALI), FRUIT AND VEGETABLE CONCENTRATES (COLOR), COCOA POWDER, GUAR GUM, NATURAL FLAVORS, LEMON JUICE CONCENTRATE, CARRAGEENAN, MILK FAT, SOY LECITHIN.
And here’ the Nutrition Facts label for a pint.
The new serving size is 2/3 cup and you get three of those in the container at 340 calories each.  Eat the whole pint and you’ve done half your daily calories along with 78 grams of added sugars (oops).
Half-Baked has even more!
If ever a situation called for moderation, this one is it.

Another food safety hazard: cake mix

The CDC is investigating an outbreak of illnesses from toxic E. coli most likely caught from commercial cake mix, of all things.

State and local public health officials are interviewing people about the foods they ate in the week before they got sick. Of the eight people interviewed, six (75%) reported tasting or eating raw batter made with a cake mix. People reported buying different varieties and brands of cake mix.

Even so, the cases are related.

DNA fingerprinting is performed on bacteria using a method called whole genome sequencing (WGS). WGS showed that bacteria from sick people’s samples are closely related genetically. This means that people in this outbreak likely got sick from the same food.

FDA is conducting a traceback investigation using purchase records from locations where sick people bought cake mix to try to determine a common cake mix brand or production facility.

I’m guessing that the source of the E. coli is contaminated flour.

This is not the first time that eating raw cake mix has caused illness.

As Food Safety News reports, another cake mix episode occurred in 2018, but that time it was from Salmonella (maybe from eggs?).

It also reports previous incidents with raw flour.

Raw flour and other ingredients can be individually contaminated and then cross-contaminate the entire mix.

Raw flour has caused two outbreaks in recent years, one in 2016 and another in 2019.

About 100 people are known to have been sickened with E. coli from eating raw flour.

I’ve posted previously about safety problems with General Mills flour.

And in 2009, there were E. coli problems with raw cookie dough; but then it was hard then to figure out whether the cause was eggs or flour.

Now, the FDA is testing cake mixes to try to identify a common source.

While all this is going on, the CDC advises:

Eating raw cake batter can make you sick. Raw cake batter can contain harmful germs like E. coli. Germs are killed only when raw batter is baked or cooked. Follow safe food handling practices when you are baking and cooking with cake mixes, flour, and other raw ingredients:

Good advice, and easier to follow with cake mixes than with cookie dough, alas.

Annals of food safety: General Mills Flour

The CDC has started a page on the E. coli O121 (STEC O121) outbreak linked to General Mills flour:

In interviews, ill people answered questions about the foods they ate and other exposures in the week before they became ill. Sixteen (76%) of 21 people reported that they or someone in their household used flour in the week before they became ill. Nine (41%) of 22 people reported eating or tasting raw homemade dough or batter. Twelve (55%) of 22 people reported using Gold Medal brand flour. Three ill people reported eating or playing with raw dough at restaurants.

The CDC’s “At A Glance”

  • Case Count: 38
  • States: 20
  • Deaths: 0
  • Hospitalizations: 10
  • Recall: Yes
 Here’s the “epi curve”—the graph of when people became ill and how many.

It looks like cases are—or were—popping up one at a time.  There is always a reporting lag.

While waiting for more information, the CDC recommends:

  • Do not use, serve, or sell the recalled flours.
  • Do not eat raw dough or batter, whether made from recalled flour or any other flour.
  • Bake items made with raw dough or batter before eating them.
  • Do not taste raw dough or batter.
  • Do not serve raw dough to customers or allow children and other guests to play with raw dough.

But really. Gold Medal flour?  If flour is used for cooking or baking, the bacteria would be killed.

OK.  I totally get eating raw cookie dough.  I did plenty of that back in the day when I baked cookies for my kids, and they helped clean the bowl.  Eating raw cookie dough may sound disgusting, but the mix is truly delicious.

If you’ve never tried it, now is not a good time to start.  In 2009, there was a really nasty E. coli outbreak from eating pre-packaged raw cookie dough.

But eating or playing with raw dough in restaurants?   Is this common practice?  News to me.
