Introduction

Food poisoning, also known as foodborne illness, is a common condition caused by the consumption of contaminated food or beverages. Pathogens such as bacteria, viruses, parasites, and toxins are the primary culprits, with symptoms ranging from mild gastrointestinal discomfort to severe dehydration and even death. Early diagnosis and appropriate management are crucial in minimizing complications and improving patient outcomes [1].

Food poisoning is typically caused by the ingestion of food contaminated with harmful microorganisms or their toxins. The most common pathogens include Salmonella, Escherichia coli (particularly the O157:H7 strain), Campylobacter, Norovirus, and Clostridium botulinum. These pathogens can cause a variety of symptoms depending on the type of organism and the amount of contamination. Some pathogens, such as Staphylococcus aureus and Bacillus cereus, produce toxins that can cause rapid-onset illness, while others, like Salmonella or Campylobacter, may result in slower onset symptoms [2].

Once ingested, these pathogens or their toxins enter the digestive tract, where they can cause inflammation of the stomach and intestines, leading to symptoms such as nausea, vomiting, abdominal pain, diarrhea, and fever. In severe cases, the infection may spread beyond the gastrointestinal system, leading to more systemic symptoms such as septicaemia [3].

The clinical presentation of food poisoning can vary depending on the causative organism. The most common symptoms include nausea, vomiting, abdominal cramps, diarrhea (often watery or bloody), and fever. Symptoms typically begin within hours to days after consumption of contaminated food, with the severity depending on the pathogen involved [4].

In cases of Salmonella or Campylobacter infection, patients may present with fever, chills, and abdominal cramping in addition to diarrhea. Escherichia coli infections, particularly those caused by the Shiga toxin-producing strain, may lead to bloody diarrhea and, in severe cases, hemolytic uremic syndrome (HUS), which can cause acute kidney failure. In contrast, Norovirus typically causes a sudden onset of vomiting and diarrhea, often in a cluster of people, such as in outbreaks in schools or cruise ships [5].

Diagnosis of food poisoning is primarily clinical, based on the patient’s history of exposure and presenting symptoms. A thorough history, including the type of food consumed, the onset and duration of symptoms, and any recent outbreaks in the community, can help narrow down potential pathogens. However, laboratory testing is often necessary to identify the specific causative organism and guide treatment decisions [6].

Stool cultures, PCR (polymerase chain reaction) tests, and enzyme-linked immunosorbent assays (ELISA) are commonly used to identify pathogens. Stool samples may be cultured to identify bacterial pathogens, and viral or parasitic infections can be detected using molecular methods. In cases where the illness is caused by a toxin, specific assays may be required to detect the presence of toxins, such as the botulinum toxin in cases of botulism [7].

The majority of food poisoning cases are self-limiting and can be managed with supportive care. The primary treatment goal is to prevent dehydration and alleviate symptoms. Oral rehydration solutions (ORS), which contain electrolytes and glucose, are essential to replace fluids lost through vomiting and diarrhea. In severe cases of dehydration or when oral rehydration is not possible, intravenous fluids may be necessary [8].

Antibiotic treatment is generally not recommended for most cases of food poisoning, as it may prolong the illness or lead to complications. However, antibiotics may be indicated in cases of certain bacterial infections, such as Shigella or Salmonella in immunocompromised individuals or in cases of invasive infection. For Clostridium botulinum poisoning, antitoxin administration is critical [9].

For bacterial infections like Campylobacter and Salmonella, supportive care remains the cornerstone of treatment. In some cases, particularly in children and elderly patients, antimicrobial therapy may be considered, although this decision should be made carefully to avoid complications such as antibiotic resistance [10].

Conclusion

Food poisoning remains a significant health concern globally, with a range of causative pathogens and varying clinical presentations. Timely diagnosis and appropriate management, including rehydration and supportive care, are essential in treating most cases. Prevention through proper food handling and hygiene practices is the key to reducing the incidence of foodborne illness. For high-risk populations, careful monitoring and early intervention can prevent complications and improve outcomes. Clinicians must remain vigilant in recognizing the signs and symptoms of food poisoning to ensure that patients receive the best care possible.
