President Obama entered office amid one of the worst times for food

safety.  January through April of 2009 saw an extraordinary number of

recalls and elevated levels of illness due to the hundreds of products

that were contaminated with Salmonella-laced peanuts and, to a lesser

degree, pistachios. The number of recalls in the first few months of his

presidency is an extreme outlier. The average number of recalls per

month for January through April 2009 was around 155, and the average of

the following months through May 2011 was around 15.


the greatest number of recalls were issued in Obama’s first few months

in office, the largest number of outbreaks and illnesses occurred in the

summer of 2010.  However, this data cannot show whether 2010 was an

exceptional summer, or only slightly higher than that of 2009.  The

large outbreak of Salmonella caused by contaminated eggs is a likely

contributor to the number of illness but, in addition, there were

significant numbers of outbreaks involving many other pathogens in

2010’s summer months. 


contrast to the norm, the levels of illness in early 2009 were elevated

for the winter months.  Both Salmonella and Shiga-toxin producing E.

coli experience cyclical rises in the number of infections in the


fsoy-salmonella.pngfsoy-stec.pngMany factors have been implicated in this pattern, and a more detailed article can be found at

It would follow that the number of outbreaks should also follow this

cyclical pattern, and they seem to, though less strongly. 


the number of recalls per month did not increase in summer months for

the past two years.  The recall pattern seems erratic and unrelated

completely to the illness numbers or outbreaks, except for a slight

relation between STEC outbreaks being closely followed by recalls.


is difficult to see any meaningful changes to food safety in the short

period Obama has been in office, and the even shorter time since the

January 2011 passage of the Food Safety Modernization Act, which has yet

to be fully implemented. The Obama White House has made food safety and

nutrition a priority, but realizing this and translating it into fewer

recalls, outbreaks and illnesses will take more than a couple of months.

However if you look at a longer series of years, trends do emerge.  From 2006 to May 2011 the number of illnesses due to pathogens commonly associated with foodborne transmission did not change significantly, while the number of recalls due to health risks did increase significantly.  The increase in recalls does not appear to be due to an actual increase in contamination as the number of illnesses did not deviate from its normal seasonal patterns during theses years.  Instead, the increase in recalls may be due to greater political pressure to ensure a safe food supply.

It should be noted that the peanut and pistachio recalls of early 2009 are outliers.  However, even when January through April 2009 are removed from the chart, there is still a significant increase in the number of recalls during this time period.  In fact, the increase in recalls becomes more apparent when these months are removed from the equation.

fsoy-recalls-health-risks1.pngIt will be interesting to see if the implementation of the FSMA leads to higher numbers of recalls and a decreases in the number of foodborne illnesses.
