As an amateur foodie and critic, Mike has reviewed restaurants all over the Great Lakes region.


1977’s Trini & Carmen’s Hot Pepper Sauce

One of the earliest food poisoning cases covered by national media occurred in Pontiac, Michigan. Trini & Carmen’s was a very popular Mexican restaurant in the Detroit suburbs. In March 1977, customers reported symptoms of food poisoning. The cause was traced to the used of homemade hot sauce using home-canned jalapeño peppers. 58 people became ill, resulting in one of the largest outbreaks of botulism in U.S. history. The restaurant was temporarily shut down and jars of contaminated peppers were seized. No deaths were reported.

Trini and Carmen’s remains in operation today as it is still one of the most popular Mexican restaurants in the Detroit area.

1982’s E. coli. Outbreak at McDonald's

In February through March and May through June 1982, 47 people fell ill with a rare form of E. coli after eating hamburgers at McDonald’s in Oregon and Michigan. The strain of E.coli was so rare that testing showed negative for the bacteria and hospitals had trouble knowing how to treat the patients.

The outbreak caused by this rare strain of E. coli resulted in published concerns over identifying bacteria that could affect the nation’s entire food supply and raised awareness of animals in raised in concentrated animal feeding operations (CAFOs).


1993’s E.coli Outbreak With Jack in the Box Hamburgers

This E.coli outbreak by a fast food restaurant has been deemed the most infamous food poisoning outbreak in US history. In 1993, Jack-in-the-Box introduced a specially produced food product called the “Monster Burger.” The product sold in 73 locations across California, Idaho, Washington, and Nevada. The problem was that the due to the size of the burger, it ended up serving customers undercooked patties. The burgers were only cooked to 140 degrees F, which was the minimum FDA-required temperature at that time.

The result was disastrous. 732 people were affected with E. coli. Four children died and 178 suffered permanent kidney and brain damage. The outbreak practically bankrupted the chain and led to stronger government regulations of food handling. Improved testing by Jack-in-the-Box and the industry led to a major reduction in E. coli cases in fast food hamburgers.


1997 Beef Tainted by Supplier Forced Burger King to Pull Product

Burger King suffered its first major food poisoning crisis in 1997. 16 people suffered E.coli symptoms from the tainted hamburger. As they looked for the source of the contamination, Burger King removed all hamburgers from its menu in 650 of its 1,650 locations, selling only chicken and fish.

The source turned out to be an Arkansas-based beef processor named Hudson Food. The USDA inspected the processing facility and then summarily asked Hudson to close the facility and recall the hamburger made there since June. Inspectors found that Hudson saved unprocessed meat overnight and added it to the next day's production. Hudson recalled more than 25 million pounds of beef and Burger King severed their business relationship with the meat supplier.

After the crisis, the Burger King began a campaign of advertising in newspapers around the country to clear up confusion over whether its beef is safe.


1999 Coleslaw Sickens 11 From Four Outlets of Kentucky Fried Chicken in Ohio

It was a hot summer in southern Ohio. Just after the July 4th holiday, folks who ate tainted coleslaw became sick with symptoms of E. coli. The outbreak sickened 18 people at four Cincinnati locations of Kentucky Fried Chicken; 11 were hospitalized. Ohio health officials noted that it had recorded 30 confirmed cases and 11 were attributed to KFC. Officials noted particular food-handling errors as possible explanations for the contamination: use of outer cabbage leaves, insufficient washing of cabbage, and use of unpeeled carrots.

The incident changed the way KFC outlets receive and handle coleslaw. No longer was cabbage prepped and chopped at the individual restaurants.


2000’s Meat Contaminates Melon at Sizzler

Food handling and facility layout was the culprit at two Sizzler restaurants in Wisconsin. Raw meat for tacos and sirloin tips cross-contaminated watermelon and was the source of an E. coli outbreak in July 2000. 736 people fell ill and 64 cases of E.coli were confirmed. 23 required hospitalization and a three-year-old girl died. The girl’s family and 138 other plaintiffs reached a $13.5 million settlement with Sizzler's meat supplier in 2012.

Sizzler struggled to stay alive as a restaurant chain after the outbreak. It emerged from bankruptcy in 1998. To its credit, it paid families for their medical bills as it pursued suits with its suppliers.


2003 Chi-Chi’s Salsa and Chili Con Queso

The next time you eat green onions, you will remember that they were once the source of the largest outbreak of hepatitis A ever to happen in the United States. In October 2003, approximately 640 people were affected, including 13 employees. Four died of the illness.

The source was a Chi-Chi’s Tex-Mex restaurant in Monaca, Pennsylvania. The outbreak forced the health department to provide immune globulin vaccinations and post-exposure antibodies to over 9,000 people. The outbreak was traced to uncooked green onions used as a garnish. The onions, imported from Mexico, were used in the restaurant’s salsa and chili con queso. Chi-Chi’s reputation never recovered. By the following year, the restaurant chain was no longer operating.

2008, 2013, 2014 Jimmy John's Sprout Contamination


2008, 2013, 2014 Jimmy John's Sprout Contamination

Jimmy John’s has made headlines with foodborne illnesses in the past 10 years. Since 2008, the freshly made from scratch sub sandwich chain served sprouts that resulted in E.coli sickness at least five times. A tally of reports since 2008 show 479 people affected.

One to the largest outbreaks occurred in 2014 when local officials in Michigan, California, Idaho, Montana, Utah, and Washington worked with the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) to investigate an outbreak that affected 19 people in May of 2014. Sprouts were the cause of an outbreak at least five times. In 2013, imported cucumbers from Mexico sickened nine people.

      The problem with food poisonings especially in famous restaurants can seriously affect their business image to their loyal customers. I personally think that the two main reasons of food poisoning are 1st businesses (whether the supplier or the business owner itself) wanted to save money so they tend to save most of excess preparation for the day; and 2nd lack of training or knowledge regarding proper food handling. Whatever the reasons are, what businesses must do is to be more responsible especially that they're into the food industry.
