This is a list of foodborne illness outbreaks by death toll, caused by infectious disease, heavy metals, chemical contamination, or from natural toxins, such as those found in poisonous mushrooms.
Before modern microbiology, Foodbourne illness was not understood, and, from the mid 1800s to early-mid 1900s, was perceived as Ptomaine Poisoning, caused by a fundemental flaw in understanding how it worked. While the medical establishment ditched Ptomaine theory by the 30s, it remained the public conscience until the late 60s and early 70s. Proper noting of such events only properly started after the Bon Vivant Outbreak of 1971, and was still limited in scope, thereby it was highly likely many large scale outbreaks from the 60s or earlier occurred, but were poorly documented and may have gone unnoticed, as even after the Bon Vivant case, prior to the 92-93 Jack in the Box Outbreak, many outbreaks were not widely reported. As such, the majority of entries on this list post-date that outbreak.
At the time the world's deadliest outbreak of E. coli poisoning. Butchers John M. Barr & Son provided cooked meat products to several events including a birthday party and a pensioners' luncheon club. The source of the contamination was traced to a boiler used for cooking joints and stew, and a vacuum packing machine used for cooked and raw meats. Deadliest Outbreak of the 0157 strain
An estimated that 224,000 people across the United States suffered from Salmonella enteritidis gastroenteritis after eating Schwan's ice cream when raw, unpasteurized eggs were hauled in a tanker truck that later carried pasteurized ice cream to the Schwan's plant, and the ice cream premix wasn't pasteurized after delivery to the plant. No deaths were reported due to the common symptoms and widespread reach, but statistically based on the CFR around 896 deaths occurred, potentially making this the deadliest foodbourne illness outbreak since proper record keeping started in the 60s.
Six guests and two staff members at the Loch Maree Hotel in Scotland were fatally poisoned by sandwiches made with Botulinus-contaminated duck paste. This was the first incident in the UK in which botulism was conclusively identified as the cause and remains the only large incident of microbial food contamination in the UK with 100% reported fatalities.
By mistake, an industrial grade Monosodium phosphate was added to milk produced by Morinaga Milk Industry, which contained an impurity of 5–8% arsenic. The milk powder was used for feeding infants, and many babies were poisoned. By 1981, there were still >6,000 people affected as adults with severe mental retardation and other health effects; and by 2006, >600 adults remained affected.

Between January 1, and June 14, 1985, 86 cases of Listeria monocytogenes infection were identified in Los Angeles and Orange Counties, California. Fifty-eight of the cases were among mother-infant pairs. Twenty-nine deaths have occurred: eight neonatal deaths, 13 stillbirths, and eight non-neonatal deaths. An increased occurrence of listeriosis was first noted at the Los Angeles County-University of Southern California Medical Center; all cases were in pregnant Hispanics, and all appeared to be community-acquired. A systematic review of laboratory records at hospitals in Los Angeles and Orange County identified additional cases throughout the area.

At least 13 people in eight states have died after eating cantaloupe contaminated with listeria, in the deadliest outbreak of food-borne illness in the United States in more than a decade, public health officials said on Tuesday. ... The outbreak appeared to be the third worst in the United States attributed to any form of food-borne illness, in terms of the number of deaths, since the C.D.C. began regularly tracking such outbreaks in the early 1970s. The deadliest outbreak in the United States since then occurred in 1985, when a wave of listeria illness, linked to Mexican-style fresh cheese, swept through California. A federal database says 52 deaths were attributed to the outbreak, but news reports at the time put the number as high as 84. The second-deadliest outbreak was in 1998 and 1999, when there were at least 14 deaths and four miscarriages or stillbirths in a listeria outbreak linked to hot dogs and delicatessen meats. Some sources put the death toll in that outbreak as high as 21. ...

Bon Vivant did not have adequate records and controls of production lots and distribution in order to trace the products quickly. The company also did not have the finances or manpower necessary to run a successful recall program. As a result, the FDA had to seize all the Bon Vivant soup throughout the country, more than a million cans in all. FDA said the seizure occupied 125 man years of FDA time, enough for 2,000 ordinary factory inspections for preventive purposes. After some squabbling in the courts, where the owner of the company sought to recover the seized cans for resale under the company's new name, "Moore & Co.," the soup was eventually incinerated, at the cost of nearly $150,000 to the federal government. As for Moore & Co., it appears the resurrection of the company was short-lived.
