Real Life Outbreak
Contaminated home-canned potatoes used in a potato salad at a 2015 church potluck in Lancaster, Ohio, triggered a massive foodborne botulism outbreak that infected 29 people and resulted in 1 death.
What is Clostridium botulinum
In adults, this illness is typically contracted by eating pre-formed toxins found in improperly handled home-canned foods
What is foodborne botulism
Food Sources: These types of food products—especially low-acid, home-canned varieties—are the most common culprits for foodborne outbreaks.
What are improperly preserved or home-canned foods
This common environmental source is where Clostridium botulinum spores originate before clinging to root vegetables, low-growing crops, or falling into animal feed.
What is soil
To safely destroy C. botulinum spores in low-acid foods like vegetables and meats, home canners must use this specialized piece of equipment rather than a standard water bath.
What is a pressure cooker
A notorious outbreak of Clostridium botulinum occurred in this year when 34 country club attendees in Clovis, New Mexico, fell ill from a contaminated salad bar.
What is 1978?
This common sweetener should never be given to infants under 12 months because it can carry dormant C. botulinum spores.
What is honey
This closely related Clostridium species causes lockjaw, producing a potent neurotoxin similar to botulinum toxin but with opposite spastic effects.
What is Clostridium tetani?
To prevent spores from germinating in anaerobic environments like canned goods, commercial processors use this precise combination of high heat and pressure, often reaching 250°F (121°C).
What is commercial sterilization
Because the pathogen is an obligate anaerobe, its growth can be successfully halted by exposing it to this gas, which it cannot tolerate.
What is oxygen?
In 1977, this Michigan city became home to the largest botulism outbreak in U.S. history after 59 people were sickened by improperly home-canned jalapeño peppers used in a restaurant's hot sauce.
What is Pontiac?
Unlike some bacterial toxins that cause a fever, botulinum toxin attacks the nervous system to cause this type of symmetrical, downward-moving muscle weakness
What is descending flaccid paralysis
Signs/Symptoms: Victims often first experience double vision, drooping eyelids, and slurred speech, which can progress into this life-threatening state.
What is descending flaccid paralysis
During transit, keeping non-sterile or vacuum-packed perishables continuously held below this specific temperature (40°F / 4°C) prevents the bacteria from multiplying and creating toxins.
What is refrigeration
This is the minimum duration, in minutes, that home-processed, low-acid foods should be boiled prior to serving to completely inactivate any potential botulinum toxins.
What is 10 minutes
The largest U.S. botulism outbreak in nearly 40 years occurred at an Ohio church potluck in 2015, where 29 people were sickened by a potato salad made with this improperly processed ingredient.
What are home-canned potatoes?
In infants, a C. botulinum infection causes extreme muscle weakness, lethargy, and a distinct lack of muscle tone colloquially known by this "flexible" medical nickname
What is Floppy Baby Syndrome
Incubation & Duration: Symptoms usually appear within this many hours of eating contaminated food, and full recovery from the illness can take anywhere from weeks to several months.
What is 12 to 36 hours?
Grocery stores must immediately discard packages showing this physical sign, which indicates gas production from potential microbial growth inside an anaerobic container
What is a bulging (or swollen)
While refrigeration slows vegetative growth, C. botulinum spores can only be thermally destroyed when water temperatures reach this baseline range of Fahrenheit degrees under pressure.
What is 240 to 250 °F?
In 1977, a Mexican restaurant in Pontiac, Michigan, caused 59 cases of botulism—the largest restaurant outbreak in U.S. history—due to a hot sauce made with improperly home-canned versions of these peppers.
What are jalapeños?
Derived from the Latin word botulus, meaning "sausage," the pathogen originally earned its name from an 18th-century outbreak linked to this food
What is tainted/blood sausage
The deadly neurotoxin it produces
What is botulinum toxin
Because the botulinum neurotoxin is heat-sensitive, home cooks can ensure safety by boiling home-canned foods for at least 10 minutes to achieve this effect.
What is inactivating
This preservation technique creates a high-acid environment with a pH below 4.6 using vinegar or brine, effectively inhibiting spore germination and toxin production.
What is pickling
