The Importance of Digital Communications During Infectious Diseases Oubreaks

As we all know, the H1NI pandemic has been raging on for close too 10 ten days now. Curiously, “Fear & The Flu: The New Age of Pandemics” is the title this week’s cover story in Newsweek magazine. From an informational standpoint point, “this may be too little, too late”—as the old saying goes. While the Internet has been around for over twenty years now, government agencies, most notably the US Food and Drug Administration (FDA) and the Centers for Disease Control (CDC) continue to rely almost exclusively on old media to communicate with the American public during infectious disease outbreaks. Apparently, the administrators who run these government agencies haven’t been listening closely enough to President Obama’s assertion that “we live in the digital age.”

Communications between the public and government health officials is vital when trying to manage and control infectious disease outbreaks. “Every single government agency as well as companies and non-profits need to be digitally literate and competent in a time of pandemic” asserts Eye on FDA blogger Mark Senak. For their performances in recent infectious disease outbreaks, Mark gives CDC an “A” for effort—although there is substantial room for improvement. FDA on the other hand didn’t fair as well. “The FDA is not nearly as sophisticated in terms of digital. Their only Twitter account is for food recalls.  And their YouTube channels are all confusing and unorganized. They have a long way to go.”

The Internet was originally designed as a digital tool to transmit and move large amounts of information from one place to another. That said, it is also a powerful communication vehicle that can be used to broadcast valuable, scientifically-accurate information during infectious disease outbreaks by leveraging social media tools like Twitter, Facebook and instant messaging. To that end, it’s time for public health agencies to recognize the power of digital media and craft communication plans that can be implemented in the next infectious disease outbreak.

Until next time...

Another Day--Another Salmonella Outbreak

Tainted pistachio nuts are the culprit for this week’s Salmonella outbreak.  Fortunately, Kraft Foods’ quality unit was doing its job and was able to alert consumers about the problem before the outbreak reached epidemic proportions. At present, there are only two suspected cases of Salmonella gastroenteritis that may be linked to tainted pistachios. The contamination has been traced back to a California company which, according to reports, is the second leading producer of pistachios in the US.

As I have mentioned several times before, Salmonella outbreaks are nothing new and not out of the ordinary in the food industry. However, what is new is the growing lack of regulatory compliance that seems to be pervasive at American food manufactures. Many blame declining food safety on the US FDA’s lack of trained inspectors. While this may play a role, I believe that the real problem lies with the failure of many food industry executives to make a commitment to quality outlined in FDA’s Current Good Manufacturing Practices (cGMPs). 

I have been teaching cGMP to biotechnology students for the past six years or so.  I always tell them that the regulations are meaningless unless management makes a commitment to quality. And, the only way to accomplish this is by insisting that all manufacturing taking place at a company stringently adheres to all GMP regulations and guidelines. For those you who may not be familiar with cGMPs, they are the minimum regulatory standards that must be met to insure US product (food, drugs and cosmetics) quality and safety.

Over the past decade or so, Americans have grown accustomed to a wide variety of choices when it comes to raw and processed foods. To meet demand, US food manufacturers must source and import fruits, vegetables, spices and other foodstuffs from all over the world. Regardless of the origin of a food source, cGMPs clearly state the onus is on the manufacturer (not the supplier) to perform the necessary tests to insure food safety and quality. The recent spate of Salmonella outbreaks suggests that some food manufacturers are either cutting corners or don’t fully understand what testing is necessary to guarantee food safety. Unless something changes, Americans confidence in the safety of US food supply will continue to wane.

Until next time...

Breaking Up Is Hard To Do: Should FDA Be Split Into Two Independent Agencies?

I just returned from a weekend of teaching regulatory affairs to biotechnology students at Georgetown University where I tried to convince them that the US Food and Drug Administration (FDA) is fundamentally sound despite its near demise during the Bush administration. Even before the Bush-induced wreckage, the agency was chronically understaffed, under funded and had serious leadership and morale problems. This, coupled with two nationwide Salmonella outbreaks in the past year, several highly publicized drug recalls, and steadily declining drug approval rates has prompted its critics to propose that FDA be split into two separate agencies—one that oversees the drug industry and another that would have responsibility for cosmetic and food safety. For those of you who may not know, FDA became responsible for oversight and regulation of the food and drug industries, in addition to the drugs, after passage of the Food, Drug and Cosmetic Act in 1938.

Drug industry advocates and longtime FDA critics contend that the agency as it exists today can no longer effectively oversee and insure the safety of American food and drug supplies. Critics argue that the history of FDA suggests that the agency focuses on medical products and only focuses on food safety when a crisis comes up. And when they occur, FDA is so distracted that it interferes with the drug review/approval process. While this is what FDA critics want you to believe, it is simply not the case. Despite its recent problems, the FDA has historically done an outstanding job when it comes to drug and food safety—when it is funded and staffed to appropriate levels.

Unbeknownst to the American public, food borne illnesses are very common and Americans are only alerted when the outbreaks reach a certain size. While the recent Salmonella outbreaks were larger in scope and breadth than past outbreaks, they were not extraordinary. However, they were extremely media worthy at the time that they were reported on. You may recall that at the time of the outbreaks, the American economy was beginning to fail and there was an inordinate amount of China, Mexico and free trade bashing going on in the US. Unfortunately, the news media decided to exploit the outbreaks to make a case that Americans ought to reduce their reliance on imported foods—a practice that was beginning to cut into the revenues of the US agriculture and food industries. Ironically, the Salmonella outbreaks might have been prevented if the production facilities (owned by American companies) were compliant with FDA mandated quality control and assurance regulations which were designed to insure food safety.

Drug industry advocates who argue that FDA ought to be split into two separate agencies have financial interests rather than safety concerns in mind.  As an investment banker or VC will tell you, slow, new drug approval rates can have serious financial consequences for the companies that are developing them—it can literally cost a company millions of dollars a day for every day the drug is kept off the market.  Interestingly, when FDA increased its drug approval rates in the late 1990s and early 2000s, there weren’t many industry insiders advocating a break up of the agency. Only recently, as FDA has become more risk adverse which in turn, has caused the new drug approval rates to slow again have critics begun to call for massive organizational changes at FDA.

Like I told my biotech students over the weekend, the only mechanism by which FDA can insure food and drug safety is by conducting regular inspections of drug and food manufacturing facilities. Unfortunately, FDA hasn’t been able to keep up with its mandatory inspections schedule because the agency has been under funded and poorly staffed for over a decade. Several FDA inspectors, who I talked with suggested that routine inspections of manufacturing facilities takes place every three to five years rather than every two years as required by FDA regulations. While in theory this shouldn’t affect a company’s ability to remain compliant with FDA regulations, in reality it does. Put simply, pharmaceutical and food companies, like most other for profit industries are incapable of policing themselves in the absence of regulatory oversight.

I ‘m not certain that the agency needs to be split into two separate agencies to continue to insure the safety of the American drug and food supplies. What I know is the agency needs more funding and much larger numbers of trained inspectors to be successful. In my opinion, the safety of the American food and drug supplies can only be guaranteed if the companies regulated by FDA make a commitment to quality manufacturing and play by the rules.

Until next time...

A New Year and Another Salmonella Food Poisoning Outbreak

Salmonella enteriditis, an organism dear to my heart (luckily not my posterior small intestine) is a common cause of food poisoning. As some of you may know, I did my PhD thesis work on Salmonella gastroenteritis (aka food poisoning) and I like to think that I am something of an expert on the topic. 

Typically, Salmonella food poisoning outbreaks are localized and rarely reach epidemic proportions. However, there have recently been two major nationwide Salmonella outbreaks in the US —one in 2007 and now in early 2009.

The current outbreak has afflicted 388 people in 42 states and may be caused by the same strain (Saint Paul) that was responsible for the 2007 outbreak. Ultimately, the 2007 outbreak was linked to contaminated tomatoes. The jury is still out on the cause of the most recent outbreak. Needless to say, CDC scientists are scurrying to quickly identify the source of the current outbreak because it took the agency over 5 months to conclusively identify the culprit in the 2007 epidemic. Not surprisingly, many grocery stores and restaurants suffered financially because of the outbreak.

Many of you may be wondering why Salmonella food poisoning is becoming such a problem in the US. I don’t believe that the strains responsible for the most recent outbreaks are more virulent than the ones that have traditionally caused more localized outbreaks. Instead, the reliance of food manufacturers and grocery store chains on one or two major food distributors (rather than multiple suppliers) is likely responsible for the severity and breadth of these nationwide outbreaks. This suggests that regulatory agencies ought to more closely scrutinize the microbiological quality of the operations of the major distributors. I believe that those efforts would greatly reduce the likelihood of future major outbreaks of food poisoning.

Until next time.

Salmonella in the News Again

This may be one of the more notable years for Salmonella food poisoning. First, there was a modest outbreak in the eating clubs at Princeton University and now a larger outbreak in Texas and New Mexico. This is the first time that I can recall in my almost 30 years as a card-carrying food microbiologist that there has been this many highly-publicized cases of Salmonella food poisoning in one year. Although I don’t wish Salmonella gastroenteritis on anybody, it is kind of rewarding that an organism that led to my PhD is making headlines once again. Typically, Salmonella outbreaks are not noteworthy and rarely receive much notice— usually taking a backseat to potentially life-threatening outbreaks of enteropathogenic Escherichia coli.

Like the Princeton outbreak, the exact source of the Salmonella infection is unclear. That said, public health and CDC officials are leaning towards large, raw tomatoes. In 2006, the Food and Drug Administration discovered that consumption of tomatoes in restaurants had caused a salmonella outbreak that affected 21 states. , “until the source of the outbreak is identified federal and local health officials in both states have recommended that infants, the elderly and anyone with an impaired immune system avoid eating Roma and red round tomatoes that are not grown at home or sold attached to the vine.” So far, 40 confirmed cases, with patients ranging in age from 3 to 82, have been reported in New Mexico and Texas since April. To date, 17 people have been hospitalized, but no deaths have been reported.

Molecular analyses indicated that all of the cases in New Mexico and Texas were caused by the same strain, a relatively rare serovar called Saint Paul (6th most common serovar infecting humans). Federal health officials at the Centers for Disease Control in Atlanta, GA fear that this may be the beginning of a large national outbreak of Salmonella gastroenteritis. This is because about 30 cases caused by the Saint Paul strain, have also been reported this year in Arizona, Colorado, Idaho, Illinois, Indiana, Kansas and Utah. Like the New Jersey, Texas and New Mexico outbreaks, the cause of those other outbreaks is under investigation.

Salmonella gastroenteritis generally last between four and seven days, and most people are able to recover without medical (antibiotic) treatment. But, it can sometimes lead to death in immunocompromised adults or young children. Symptoms include headache, nausea, abdominal pain, diarrhea and sometimes vomiting.  Although textbook descriptions of the pathogenesis of Salmonella gastroenteritis generally portray it as a mild illness, I can tell you that people I know (lab mates of mine) who came down with the disease (gee, how did that happen?) suggest otherwise!

I suspect that fecally-contaminated water may be source of the infection. But, then again, it has been almost 30 years since I thought about Salmonella gastroenteritis. That said, I don’t think that you ever forget the essence or minutiae of your thesis work!

For those of you who are interested, the electron micrograph of Salmonella typhimurium shown with this post is from my PhD dissertation. As I recall, the electron micrograph was taken in 1980 and the bacterium shown in the micrograph was grown for 48 hours on nutrient agar . Althought I would like to take credit for the shot (nice pose eh?),  it was taken by Phil Hegge in the Department of Bacteriology at the University of Wisconsin-Madison, my alma mater. if you look closely you may be able to see fimbriae along with the flagella.

Until next time

Princeton U Salmonella Outbreak Revisited

I apparently made a few errors in the post about the recent Salmonella food poisoning outbreak at PU (pun intended). I want to thank the anonymous member of the Princeton Graduating Class of ’09 for pointing out the inconsistencies and errors in the post.  First, the so-called “dining clubs” are actually called eating clubs. Second, fraternities and sororities are allowed at PU and I hear that they are alive and well. Finally, I inadvertently noted that the University has severed contracts with several of its produce suppliers which may have been the putative source(s) of the outbreak. In fact, the University didn’t cancel contracts but only temporarily closed a few of the eating stations at the Frist Campus Center. My local newspaper reported that contracts where severed–I guess you truly can’t believe everything that you read!

I was duly chastised for not adequately verifying my information before I hastily crafted the post. I stand corrected and will attempt to be more vigilant in the future. That said, I think that my lack of understanding of the practices and customs at Princeton University is directly related to the fact that I attended Cornell as an undergraduate. Mea Culpa!

Until next time…

Salmonella Outbreak at Princeton University--Oh My!!!

Yes, even the Ivy League isn’t immune to food poisoning outbreaks from time-to-time. There are currently 10 confirmed cases of Salmonella food poisoning at Princeton U. Another 50 people or so have also fallen ill with gastrointestinal symptoms consistent with Salmonella food poisoning.  As a precaution, university officials have temporarily discontinued doing business with their produce suppliers. For those of you who don’t know, Princeton is famous (infamous?) for its so-called dining clubs. These clubs take the place of sororities and fraternities which are not allowed at this august institution of higher education. Obviously, there is more than eating that goes on at these “dining clubs.”

The reason I am blogging about the outbreak is two-fold. First, I live about seven miles from Princeton and it has been all over the local news. Second, I did my PhD work on the pathogenesis of Salmonella gastroenteritis. So, Salmonella food poisoning is dear to my heart (thankfully, not my gastrointestinal tract). Many infectious disease experts tend to dismiss the seriousness of Salmonella gastroenteritis. This is likely because it is usually not as devastating as shigellosis or infections caused by enteroinvasive strains of Escherichia coli (which is actually Shigella masquerading as E. coli). As my major professor once put it “You know when you have Salmonella gastroenteritis—if you can’t decide than it is not salmonellosis.”

I am happy to report that I never came down with gastroenteritis while working for over three years with enteroinvasive Salmonella strains (even though I was routinely mouth pipetting and eating lunch in the lab; practices which aren’t acceptable by today’s standards). I like to think that “the bugs” were afraid of me. Alternatively I had either a great immune system or extremely good aseptic techniques. Whatever the reason, it is always embarrassing when card-carrying microbiologists come down with the disease(s) that they are studying. Luckily, I never came down with the disease caused by the bacterium that I was studying during my first postdoctoral fellowship—Neisseria gonorrhoeae. That would have been extremely difficult to explain!

Until next time…
