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.

Nestlé’s (no relation) social responsibility

I love corporate social responsibility reports .  I collect them.  Someone from Nestlé was kind enough to send me its shiny new reportNutritional Needs and Quality Diets: Creating Shared Value, 2008.  Nestlé is a very big food company.  For starters, it employs 283,000 people in 84 countries.  It sold $96.5 billion in products last year for a not-too-shabby profit of $16 billion (dollar figures are converted from Swiss francs and rounded off).   Bottled water accounted for $8 billion in sales (down 1.6% from the previous year), pet food for $11 billion, and ice cream for $18 billion.  I looked for – but could not find – the sales figures for Nestlé’s infant formula, the source of much controversy about this company.

As for social responsibility, the company says its education programs have reached 9 million people.  And by changing the recipes of its foods, it has eliminated 75,000 tons of trans fat from its products, along with 15,000 tons of salt and 638,000 tons of sugars.  Nestlé is also the largest fortifier of foods with vitamins and minerals.

Will these kinds of approaches help people eat healthier diets?  As David Ludwig and I discussed in a JAMA article last October, we are skeptical.  But read and decide for yourself!

March 19 update: and thanks to Jaybird for sending today’s example of Nestlé’s corporate responsibility in India.

Nestlé Corp. refuses to stop marketing junk foods to kids

The giant food company, Nestlé (no relation), says it will not join the food industry’s voluntary efforts to stop marketing junk foods to kids.   Why not?  Here’s one guess: maybe the company doesn’t want to make promises it knows it can’t keep.
