Staphylococcal Food Poisoning History

The history of Staphylococcal food poisoning reveals a fascinating journey of scientific investigation and discovery. Vaughan and Sternberg, pioneers in the field, laid the foundation in 1884 by scrutinizing the inaugural documented case in Michigan, USA. This pivotal investigation traced the origins of Staphylococcal food poisoning back to the consumption of contaminated cheese, offering an early glimpse into the dynamics of foodborne illnesses.

A decade later, in 1894, J. Denys added a significant chapter to the narrative. His study delved into an outbreak of illness within a family, pinpointing the consumption of meat from a cow that had succumbed to vitullary fever as the culprit. Denys astutely identified the presence of pyogenic staphylococci, marking a crucial milestone in connecting specific bacterial strains to foodborne diseases.

The year 1907 saw Owen's groundbreaking work, isolating staphylococci from dried beef associated with an outbreak displaying distinct Staphylococcal food poisoning symptoms. This marked progress provided deeper insights into the modes of bacterial contamination in various food sources, contributing to the evolving understanding of food safety.

Fast forward to 1914, M. A Barber's research brought the long-sought confirmation of staphylococci's role in food poisoning. By identifying a toxin substance produced by these bacteria as the primary cause of Staphylococcal food poisoning, Barber made history. His groundbreaking findings unveiled a new paradigm, demonstrating that a toxic substance within the food itself, rather than the bacteria alone, was responsible for the illness. Barber's meticulous work included the extraction of staphylococci from contaminated milk obtained from a cow suffering from mastitis, further solidifying the link between bacterial contamination and foodborne intoxication.

In the aftermath of World War I, in 1922, Baerthlein reported a massive outbreak affecting 2000 soldiers of the German army. This event underscored the potential widespread impact of Staphylococcal food poisoning during crisis situations and emphasized the crucial role of bacteria in food safety.

The historical narrative continued with B Gail Dack's rediscovery of the role of staphylococci in food poisoning in 1929. Investigating an outbreak linked to a Christmas cake, Dack reinforced the significance of ongoing vigilance in monitoring diverse food sources for potential bacterial contamination.

Today, the collective knowledge amassed over the years has established that food poisoning caused by staphylococci is a form of foodborne intoxication. The causative agents, staphylococcal enterotoxins (SEs), serve as the focal point in understanding and preventing Staphylococcal food poisoning, showcasing the ongoing importance of historical investigations in shaping food safety protocols.

Foodborne illness due to bacterial food poisoning

Foodborne illness, one of the greatest public health and food industry concerns.

In some infections, microbes produce toxins inside the infected person’s body. In food poisoning cases, the microbes produce toxins the contaminated food and when people eat the food, the toxins make them very ill.

If a person eats food containing a fairly large amount of a toxin, it is like that he or she will be ill that day.

The disease is characterized by rapid onset, severity of symptoms, but usually a short duration.

Examples include botulism due to the formation of botulinum toxin in the food from the growth of certain clostridial species, staphylococcal and histamine poisoning.

Where these toxic food poisonings result from bacterial toxins, the poisons are synthesized in the food. 

Today, staphylococcal food poisoning ranks as the second most reported of all types of foodborne disease. Because most staphylococcal outbreaks probably t unreported, staphylococcal food poisoning could actually be the most common type.

Symptoms of foodborne illness are diarrhea, nausea, abdominal pain or vomiting without fever or upper respiratory distress.

Most foodborne illnesses are caused by the mishandling of food or the faulty cooking or storage of food, either in food service establishment or at home.

Toxic shock syndrome

Toxic shock syndrome was an outbreak when it was first recognized. Toxic shock syndrome is an acute –onset illness characterized by early onset of multi-organ involvement and shock. It causes by gram-positive bacteria that rapidly progresses ro chock with multi-organ failure. Toxic shock syndrome most commonly presents in healthy individuals with intact immune system.

Staphylococcal toxic shock syndrome, STSS, was the first type of toxic shock syndrome diagnosed and consequently has the most thorough epidemiological database.

The following criteria must be made in order to confirm Toxic shock syndrome:
*Fever – temperature higher than 102 °F
*Rash - diffuse, sunburnlike rash
*Skin peeling – usually 0-2 weeks after onset of illness, primarily on palms and soles.
*Low blood pressure
*Involvement in three or more of the following systems
*Laboratory tests to differentiate Toxic shock syndrome from other infectious diseases

Toxic shock syndrome is associated with three etiological agents:
*Staphylococcus aureus infection
*Streptococcus pyogenes infection
*Clostridium sordellii – soft tissue infections

Staphylococcal toxic shock syndrome became well known in the late 1970s when it was described in menstruating women using tampons.

Staphylococcal Poisoning

Staphylococcal Poisoning
Food intoxications are those diseases in which the causative organism grows in the food and produces a chemical substance in the food that is toxic to humans and other animals.

The symptoms of staphylococcal poisoning are nausea, vomiting, abdominal cramps, diarrhea, and prostration.

While the symptoms last, suffering may be acute, but this is usually for a period of only a few hours.

Generally, the patient recovers without complications. The incubation period after ingestion or eating food containing the toxin is from 1 to 7 usually 3 to 6 hours.

Staphylococcal poisoning is often wrongly called ptomaine poisoning. Ptomaines are produced by bacteria in some foods when extreme decomposition occurs.

Most ptomaines are not poisonous, and it is unlikely that many people would eat foods decomposed to this extend. It is probable, therefore, that ptomaine poisoning rarely occurs.
