30 Years Later: The Foodborne Illness Outbreak that Changed Food Safety

In January, we hit a major anniversary.  One I am betting snuck by many of you – including me! January marked 30 years since the deadly 1993 E. coli O157:H7 outbreak at Jack in the Box restaurants on the west coast. The anniversary wasn’t on any of the major news networks that I recall. It did make it into a few newspapers, at least one or two of the newspapers that are left.  It wasn’t until late-February that I realized it.

You might be asking yourself, why is such an anniversary noteworthy? I am betting many of our readers won’t necessarily understand or appreciate the state of food safety in the United States before this outbreak.  To be honest, I’ve only read about the status of food safety pre-1993.  I was just entering high school at this time, so the thought of the current status of food safety in the United States was not necessarily top of mind for me.

To understand what changed, it is important to understand the outbreak, too.  Some of you may be familiar with it but may not necessarily know some of the details. It wasn’t the first E. coli outbreak in the United States, and it certainly would not be the last.


One could argue that without a Jack in the Box-like food safety incident, we wouldn’t have the advanced food safety system in the United States that we have today.


In 1982, another fast-food behemoth, which I affectionately call the Golden Arches Supper Club, was at the center of an E. coli outbreak that would sicken 47 individuals across two states. But, at the time, the government really didn’t name names of the source of outbreaks nor was the information broadcast much to the public.  Even if it was, it may have fallen upon deaf ears.

While it barely made the news, McDonald’s took notice and outsourced research into the issue. The microbiologist they hired recommended new clamshell-style grills that were not to be opened until the meat was thoroughly cooked. This may have been one of the first instances of removing the “human element” from the food production system to protect food.

Fast forward 10 years. Bill Clinton was set to become the nation’s 42nd President in late-January 1993.  But on the west coast, investigators were receiving word of widespread illnesses among the public that were causing concern. In the end, 73 different Jack in the Box restaurants were linked to the illness that caused over 700 people to fall ill, of these, 171 were hospitalized and four children died. In his first month in office, President Clinton would be responding to questions about the outbreak from parents of a child who died from the outbreak.

As a result of the outbreak, the Federal government made sweeping reforms to food safety policies and practices.  E. coli O157:H7 was upgraded to a reportable disease by health departments across the United States. Slaughterhouse practices, including product testing and overall operations, were improved. In fact, meat and poultry inspections worldwide were changed as a result of the outbreak. The Model Food Code was updated to increase the end-point-cooking temperature of ground beef from 140°F to 155°F. Restaurant operators started to focus more on eliminating cross contamination and the importance of food safety education for those on the frontline of restaurants across the United States became paramount.

One could argue that without a Jack in the Box-like food safety incident, we wouldn’t have the advanced food safety system in the United States that we have today. But, for those four children who died from the outbreak and countless others who suffered, what a price to pay. The famous food safety attorney, Bill Marler, who represented Jack in the Box patients was left wondering if the 1982 McDonald’s outbreak had made national news like the Jack in the Box outbreak did, would the Jack in the Box outbreak ever happen? Perhaps it would and perhaps it would not. Had the McDonald’s outbreak made national news, would we be 10 years more advanced in food safety than we are today?

Coli and how you might protect yourself and your establishment, check out our previous blog on the issue.  Later this month, be on the lookout for our first SafeBites Webinar Series to be released! We have an exciting set of webinars that we are planning this year. In the meantime, if you have any food safety questions, we are a quick email away and would be happy to assist. Risk Nothing. 

30 Years Later: The Foodborne Illness Outbreak that Changed Food Safety

In January, we hit a major anniversary.  One I am betting snuck by many of you – including me!

Does Temperature Really Matter when Washing your Hands?

In January, I reviewed the changes to the 2022 Food Code in my blog (check out Part I and Part II), and one change to the food code that I had mentioned, but didn’t discuss in-depth, was the change that lowered the water temperature a hand sink was required to produce to 85°F, as noted in Section 2-202.12 of the code. This requirement has been in place since the publishing of the 2001 Food Code, which required a water temperature of 100°F. Prior to this, 110°F was required (see the 1999 Food Code). So why the change and does water temperature when washing your hands really matter?

Hand sinks: Often Taken for Granted, but an Essential Part to Effective Hand Hygiene

Late in January, I received a question about hand sinks in a foodservice operation.  The question pertained to school staff (teachers and aides) who were using a hand washing sink in the school kitchen.  The question came as a matter of who was allowed access to the kitchen to use the sink, but the question itself caused me to go down a rabbit hole of requirements for hand washing sinks in foodservice operations.
