.According to the most recent review of foodborne disease outbreaks in the U.S. in 2008 by the Center for Science in the Public Interest (CSPI), seafood, produce and poultry were associated with the most outbreaks. Produce is responsible for the greatest number of illnesses each year (2,062), with nearly twice as many illnesses as poultry (1,112). Dairy products are at the bottom of the list. They cause the fewest outbreaks and illnesses of all the major food categories – beef, eggs, poultry, produce and seafood.
According to the CDC, during the period from 1990 − 2006, there were 24,000 foodborne illnesses reported each year on average. Of those, 315 per year are from dairy products. This means dairy products account for about 1.3% of foodborne illnesses each year. That’s not exactly an alarming number, considering that more than 75% of the population consumes dairy products regularly.
It’s also important to note that the outbreaks and illnesses associated with dairy products are generally mild compared to other foods.
According to the CSPI report above, approximately 5,000 people are killed every year by foodborne illness. From 2009 − 2011, three high profile outbreaks involving peanuts, eggs and cantaloupe alone accounted for 2,729 illnesses and 39 deaths. (1) Yet there have only been a handful of deaths from pasteurized dairy products in the last decade, and there hasn’t been a single death attributed to raw fluid milk since the mid-1980s, in spite of the fact that almost 10 million people are now consuming it regularly
Why the CDC report can’t be taken at face value
The CDC report claimed that unpasteurized milk is 150 times more likely to cause foodborne illness than pasteurized milk, and such outbreaks had a hospitalization rate 13 times higher than those involving pasteurized dairy products.
According to senior author of the CDC study, Barbara Mahon:
When you consider that no more than 1% of the milk consumed in the United States is raw, it’s pretty startling to see that more of the outbreaks were caused by raw milk than pasteurized.
But can these claims be taken at face value? No.
There are several problems with the CDC report:
First and foremost, the CDC doesn’t include the dataset they used, so we can’t analyze how they reached their conclusions. Fortunately, the CDC data for foodborne illness, as well as data from other institutions and peer-reviewed studies, are readily available online.
There are about 24,000 foodborne illnesses reported each year. Yet by the CDC’s own admission, this represents only a tiny fraction of the true number of foodborne illnesses that occur. In 1999, CDC scientists used an estimate of the overall prevalence of diarrhea and vomiting to calculate the “true” incidence of foodborne illness as 76 million cases per year! Put another way, 99.97% of foodborne illnesses go unreported.
A food vehicle was identified in only 43% of the reported outbreaks and only half of these were linked to a single food ingredient. What this means is that the true prevalence of foodborne illness that can be attributed to a particular food is much higher than what is reported. It also means that the data linking specific outbreaks with specific foods is such a tiny sample of the total that even small errors or biases in the reporting of outbreaks would seriously skew the results.
To calculate the number of people that drink unpasteurized milk, the CDC used an older, lower estimate (1%) of the number of people that drink raw milk. This is curious because a FoodNet survey done by the CDC itself in 2007 found that 3% of the U.S. population – about 9.4 million people – regularly consumes raw milk. That number is likely even higher today with the growing popularity of raw milk. (In 2010 alone, raw milk sales increased by 25% in California.) Why did they do this? If you’re a cynic, you might conclude that they used the lower estimate to exaggerate the risk of drinking raw milk.
They combined data from outbreaks and illnesses associated with “bathtub cheese” (i.e. Mexican-style Queso Fresco made illegally at home) made from raw milk, and raw fluid milk. Queso Fresco is inherently more dangerous than raw milk, and is associated with more serious outbreaks and illnesses. Again, this distorts the data and makes raw milk seem more dangerous than it really is. (Note: commercial, properly aged raw milk cheese has never been implicated in a disease outbreak.)
