Zatrucie pokarmowe
Diagnostyka i diagnoza

Zatrucie pokarmowe diagnozuje się przede wszystkim na podstawie objawów klinicznych oraz szczegółowego wywiadu epidemiologicznego, uwzględniającego rodzaj spożytych pokarmów, czas wystąpienia symptomów oraz ich charakterystykę. Czas inkubacji jest kluczowy w różnicowaniu etiologii: objawy pojawiające się poniżej 6 godzin sugerują zatrucie toksynami bakteryjnymi (np. Staphylococcus aureus), natomiast objawy po 12 godzinach wskazują na infekcję bakteryjną, wirusową lub pasożytniczą (np. Salmonella, E. coli). Badanie fizykalne koncentruje się na ocenie stopnia odwodnienia (suchość błon śluzowych, spadek ciśnienia tętniczego, tachykardia) oraz obecności objawów sugerujących inwazyjność procesu (np. bolesność brzucha, krew w kale). W cięższych przypadkach lub u pacjentów z grup ryzyka (immunosupresja, ciąża, osoby starsze) wskazane jest wykonanie badań laboratoryjnych, w tym mikroskopii kału, posiewów bakteriologicznych, testów PCR oraz badań krwi (morfologia, elektrolity, posiew krwi).

Diagnostyka zatrucia pokarmowego

Zatrucie pokarmowe to choroba wywołana spożyciem żywności lub wody zanieczyszczonej bakteriami, wirusami, pasożytami lub toksynami. Diagnoza zatrucia pokarmowego najczęściej opiera się na objawach klinicznych, jednak w niektórych przypadkach konieczne jest przeprowadzenie bardziej szczegółowych badań diagnostycznych w celu potwierdzenia rozpoznania i identyfikacji czynnika wywołującego chorobę.123

Diagnoza na podstawie objawów i wywiadu

Lekarze najczęściej diagnozują zatrucie pokarmowe na podstawie objawów zgłaszanych przez pacjenta. W przypadku łagodnych objawów, które ustępują w krótkim czasie, zazwyczaj nie są wymagane dodatkowe badania diagnostyczne.123 Podczas wywiadu lekarz zbiera informacje dotyczące:

  • Rodzaju spożytych pokarmów i napojów w ciągu ostatnich dni
  • Czasu wystąpienia objawów po spożyciu podejrzanego pokarmu
  • Charakteru i nasilenia objawów
  • Czy inne osoby, które spożywały ten sam pokarm, również zachorowały
  • Niedawnych podróży
  • Historii medycznej pacjenta123

Czas pomiędzy spożyciem skażonej żywności a wystąpieniem objawów może pomóc w zidentyfikowaniu prawdopodobnego patogenu:

  • Objawy występujące w ciągu mniej niż 6 godzin sugerują zatrucie toksynami bakteryjnymi wytworzonymi w żywności przed jej spożyciem (np. gronkowiec złocisty)
  • Objawy występujące po 12 godzinach lub później sugerują infekcję bakteriami wytwarzającymi toksyny po spożyciu żywności (np. niektóre szczepy E. coli) lub bakteriami, wirusami czy pasożytami uszkadzającymi komórki wyściełające jelito (np. salmonella)12

Badanie fizykalne

Podczas badania fizykalnego lekarz koncentruje się na ocenie stopnia odwodnienia oraz poszukiwaniu objawów sugerujących konkretną przyczynę zatrucia pokarmowego.12 Badanie może obejmować:

  • Pomiar ciśnienia krwi i tętna – w poszukiwaniu objawów odwodnienia
  • Ocenę nawodnienia (suchość błon śluzowych, zmniejszona wilgotność skóry pod pachami, zmniejszona ilość moczu)
  • Badanie brzucha w poszukiwaniu tkliwości, bolesności lub napięcia mięśniowego
  • Pomiar temperatury ciała
  • Badanie per rectum w celu sprawdzenia obecności krwi w kale123

Badania laboratoryjne

W przypadku ciężkiego przebiegu zatrucia pokarmowego, gdy objawy utrzymują się dłużej niż 3-4 dni, występuje gorączka, krwawa biegunka lub gdy pacjent należy do grupy wysokiego ryzyka (osoby z obniżoną odpornością, kobiety w ciąży, osoby starsze), lekarz może zlecić dodatkowe badania laboratoryjne.12

Badania stolca

Badania kału są najczęstszymi testami laboratoryjnymi w diagnostyce zatrucia pokarmowego i mogą obejmować:12

  • Mikroskopowe badanie kału na obecność leukocytów i erytrocytów – pomaga odróżnić chorobę inwazyjną od nieinwazyjnej
  • Barwienie metodą Grama i błękitem metylenowym Loefflera
  • Badanie parazytologiczne kału w kierunku jaj i pasożytów
  • Posiew bakteriologiczny kału w kierunku patogenów jelitowych (np. Salmonella, Shigella, Campylobacter) – obowiązkowy, gdy w próbce kału stwierdzono leukocyty lub krew, pacjent ma gorączkę lub objawy utrzymują się dłużej niż 3-4 dni
  • Badania w kierunku toksyn bakteryjnych (np. toksyna Clostridium difficile)
  • Badania PCR (łańcuchowa reakcja polimerazy) stolca – umożliwiają szybką identyfikację patogenów123
Badania krwi

Badania krwi mogą być pomocne w ocenie stanu zapalnego organizmu, stopnia odwodnienia oraz wykluczenia innych przyczyn objawów:12

  • Morfologia krwi z rozmazem – ocena odpowiedzi zapalnej
  • Elektrolity, mocznik, kreatynina – ocena stopnia odwodnienia i funkcji nerek
  • Posiew krwi – w przypadku wysokiej gorączki lub podejrzenia posocznicy
  • Poziom lipazy lub amylazy w surowicy – w przypadku podejrzenia zapalenia trzustki
  • Próby wątrobowe – przy podejrzeniu zajęcia wątroby
  • Przeciwciała IgM przeciwko wirusowemu zapaleniu wątroby typu A lub E123
Inne badania diagnostyczne

W przypadku niejednoznacznych wyników badań kału lub utrzymujących się objawów, szczególnie u pacjentów z obniżoną odpornością, mogą być konieczne dodatkowe badania diagnostyczne:12

  • Sigmoidoskopia/kolonoskopia z biopsją – pomocna w diagnostyce choroby zapalnej jelit, biegunki związanej z antybiotykami, shigellozy, czerwonki amebowej
  • Ezofagogastroduodenoskopia (EGD) z aspiracją treści dwunastniczej i biopsją
  • Badania obrazowe (zdjęcie przeglądowe jamy brzusznej, tomografia komputerowa) – rzadko stosowane w diagnostyce zatrucia pokarmowego, ale mogą pomóc wykluczyć inne przyczyny objawów, takie jak niedrożność jelit lub perforacja
  • Test na obecność toksyny botulinowej – w przypadku podejrzenia botulizmu
  • Badanie moczu – w celu oceny stanu nawodnienia123

Diagnostyka różnicowa

Ważnym elementem diagnostyki zatrucia pokarmowego jest wykluczenie innych stanów chorobowych o podobnych objawach. Diagnostyka różnicowa może obejmować:12

Szczególna diagnostyka w przypadku podejrzenia epidemii

W przypadku podejrzenia ogniska zatrucia pokarmowego (gdy wiele osób choruje po spożyciu tego samego pokarmu), procedury diagnostyczne mogą być rozszerzone:12

  • Badanie próbek podejrzanej żywności w celu identyfikacji patogenu lub toksyny
  • Zgłoszenie przypadku do lokalnych władz sanitarno-epidemiologicznych
  • Bardziej szczegółowe badania laboratoryjne w celu precyzyjnej identyfikacji szczepu patogenu
  • Dochodzenie epidemiologiczne mające na celu identyfikację źródła zatrucia i zapobieganie dalszym zachorowaniom123

Diagnostyka w zależności od rodzaju patogenu

Metody diagnostyczne mogą różnić się w zależności od podejrzewanego patogenu wywołującego zatrucie pokarmowe:12

Bakteryjne zatrucia pokarmowe

W przypadku podejrzenia bakteryjnego zatrucia pokarmowego (np. Salmonella, Campylobacter, E. coli, Shigella):12

  • Posiew kału na podłoża selektywne i różnicujące – standardowa metoda diagnostyczna
  • W przypadku Salmonella i innych bakterii inwazyjnych może być konieczny posiew krwi
  • Badania PCR stolca pozwalają na szybszą identyfikację patogenów niż tradycyjne posiewy
  • W przypadku podejrzenia produkcji toksyn (np. Staphylococcus aureus, Bacillus cereus) – badania w kierunku obecności toksyn w żywności lub kale123

Wirusowe zatrucia pokarmowe

W przypadku podejrzenia wirusowego zatrucia pokarmowego (np. norowirusy, rotawirusy):12

  • Testy immunoenzymatyczne (ELISA) do wykrywania antygenów wirusowych w kale
  • Badania PCR stolca – czulsze niż testy antygenowe
  • Szybkie testy diagnostyczne w kierunku norowirusów lub rotawirusów – nie zawsze dostępne w warunkach ambulatoryjnych12

Pasożytnicze zatrucia pokarmowe

W przypadku podejrzenia zatrucia pokarmowego wywołanego przez pasożyty (np. Giardia lamblia, Cryptosporidium, Entamoeba histolytica):1

  • Mikroskopowe badanie kału na obecność jaj i pasożytów – często konieczne jest wielokrotne badanie próbek
  • Test struny (entero-test) – w przypadku podejrzenia giardiazy
  • Testy immunoenzymatyczne do wykrywania antygenów pasożytów w kale
  • Testy na obecność Toxoplasma u osób z grup wysokiego ryzyka12

Zatrucia toksynami pokarmowymi

W przypadku podejrzenia zatrucia toksynami pokarmowymi (np. ciężkie zatrucie grzybami, zatrucie rybie):1

  • Badanie próbek żywności w celu wykrycia toksyn
  • W przypadku botulizmu – badanie w kierunku toksyny botulinowej w surowicy lub kale oraz badanie elektromiograficzne
  • W przypadku zatrucia ciguatoksyną – wykrywanie ciguatoksyny w rybach powiązanych z przypadkiem zatrucia
  • W przypadku zatrucia histaminą – wykrywanie histaminy w rybach powiązanych z przypadkiem zatrucia12

Znaczenie diagnostyki zatrucia pokarmowego

Szybka i dokładna diagnoza zatrucia pokarmowego ma istotne znaczenie z kilku powodów:12

  • Pozwala na wdrożenie odpowiedniego leczenia, szczególnie w przypadku ciężkiego przebiegu choroby lub u pacjentów z grup ryzyka
  • Umożliwia identyfikację źródła zatrucia, co może pomóc zapobiec dalszym zachorowaniom
  • W przypadku ognisk zatrucia pokarmowego pomaga w dochodzeniu epidemiologicznym i wycofaniu skażonych produktów z rynku
  • Przyczynia się do monitorowania trendów w występowaniu chorób przenoszonych drogą pokarmową i planowania działań prewencyjnych123

Należy pamiętać, że w większości przypadków zatrucia pokarmowego diagnoza opiera się głównie na objawach klinicznych i wywiadzie, a badania laboratoryjne są zarezerwowane dla przypadków cięższych, nietypowych lub gdy istnieje podejrzenie ogniska epidemicznego.123

  • #1 Diagnosis of Food Poisoning – NIDDK
    https://www.niddk.nih.gov/health-information/digestive-diseases/food-poisoning/diagnosis
    Doctors often diagnose food poisoning based on your symptoms. If your symptoms are mild and last only a short time, you typically wont need tests. […] In some cases, a medical history, a physical exam, stool tests, and blood tests can help diagnose food poisoning. Your doctor may perform additional tests to check for complications or to rule out other health problems. […] During a physical exam, your doctor may check your blood pressure and pulse for signs of dehydration. […] Sometimes, doctors perform a digital rectal exam to check for blood in your stool. Blood in your stool may be a sign of an infection with bacteria or parasites. […] Stool tests can show the presence of viruses, bacteria, or parasites. […] Blood tests can show signs of certain infections or signs of complications such as dehydration.
  • #1 Symptoms of Food Poisoning | Food Safety | CDC
    https://www.cdc.gov/food-safety/signs-symptoms/index.html
    The most common symptoms of food poisoning include diarrhea, stomach pain or cramps, nausea, vomiting, and fever. […] Signs of severe food poisoning include bloody diarrhea, diarrhea that lasts more than 3 days, fever over 102F, vomiting so often that you cannot keep liquids down, and signs of dehydration. […] You can get sick with food poisoning after swallowing certain germs, like Salmonella or E. coli. Your symptoms may vary, depending on the germ you swallowed. Symptoms can range from mild to serious and can last for a few hours or several days. […] If you have diarrhea or vomiting, be sure to drink plenty of fluids to prevent dehydration (not having enough water in your body). […] See a doctor if you have any symptoms that are severe, including bloody diarrhea, diarrhea that lasts more than 3 days, high fever (temperature over 102F), vomiting so often that you cannot keep liquids down, and signs of dehydration, which include not urinating (peeing) much, a dry mouth and throat, and/or feeling dizzy when standing up.

    The diagnosis is usually made on the basis of symptoms alone, and fortified if there is an accompanying history of a person eating with you who also became sick. […] If a doctor wants to pinpoint the microorganism that caused the food poisoning, you will be asked to provide a stool sample to be examined in a laboratory. Your doctor also may want to take a sample of your blood for testing. […] Information about the length of time between eating the food and the beginning of symptoms can help in diagnosing the problem: […] Less than six hours suggests that the infection was caused by a type of bacterium that creates a toxin in the food before it was eaten (such as staphylococcus) […] Twelve hours or more suggests the infection was caused by a type of bacterium that makes a toxin after the food is eaten (such as certain types of E. coli), or a bacterium, virus or parasite that can damage the cells lining the intestine (such as salmonella).

    Because infectious diarrhea can be contagious and is easily spread, rapid and definitive identification of an etiologic agent may help control a disease outbreak. […] An individual physician who obtains testing can contribute the necessary piece of data that ultimately leads to identification of the source of an outbreak. […] The differential diagnosis of patients presenting with neurological symptoms due to a foodborne illness is also complex. […] When submitting specimens for microbiologic testing, it is important to realize that clinical microbiology laboratories differ in protocols used for the detection of pathogens. […] Stool cultures are indicated if the patient is immunocompromised, febrile, has bloody diarrhea, has severe abdominal pain, or if the illness is clinically severe or persistent.
  • #1 Food Poisoning Workup: Laboratory Studies, Imaging Studies, Procedures
    https://emedicine.medscape.com/article/175569-workup
    Obtain the following laboratory studies in cases of suspected food poisoning: […] Gram staining and Loeffler methylene blue staining of the stool for WBCs help to differentiate invasive disease from noninvasive disease. […] Perform microscopic examination of the stool for ova and parasites. […] Bacterial culture for enteric pathogens, such as Salmonella, Shigella, and Campylobacter organisms, becomes mandatory if a stool sample shows positive results for WBCs or blood or if patients have fever or symptoms persisting for longer than 3-4 days. […] Perform blood culture if the patient is notably febrile. […] CBC with differential, serum electrolyte assessment, and BUN and creatinine levels help to assess the inflammatory response and the degree of dehydration.

  • #1 Food poisoning: Treatment, symptoms, and causes
    https://www.medicalnewstoday.com/articles/154555
    Food poisoning is usually easy to diagnose based on the symptoms alone, with little need for confirmation from a doctor. The symptoms a person reports are usually sufficient to inform a diagnosis. […] In some cases, stool testing is necessary. For example, if someone experiences diarrhea along with blood or it is watery for more than a few days, doctors may want a stool sample to test for parasites or bacteria. […] During an outbreak of rotavirus, for example, the doctor may request other specific tests. […] Sometimes, based on a person’s symptoms or history, a doctor may rule out other conditions, such as appendicitis, diverticulitis, or bowel obstruction.
  • #1

    Stool cultures are also indicated if many fecal leukocytes are present, which indicates diffuse colonic inflammation and is suggestive of invasive bacterial pathogens such as Shigella, Salmonella, and Campylobacter species, and invasive E. coli. […] In most laboratories, routine stool cultures are limited to screening for Salmonella and Shigella species, and Campylobacter jejuni/coli. […] Blood cultures should be obtained when bacteremia or systemic infection are suspected. […] Reporting of foodborne illnesses in the United States began more than 50 years ago when state health officers, concerned about the high morbidity and mortality caused by typhoid fever and infantile diarrhea, recommended that cases of „enteric fever” be investigated and reported. […] Health care professionals can serve as the eyes and ears for the health department by providing such information to the local or state public health authorities.

    Food poisoning or foodborne illness is caused by the consumption of food or water that is contaminated with bacterial, parasitic, or viral pathogens. […] Symptoms are most commonly gastrointestinal in nature and are typically self-limited. Some cases can lead to severe dehydration and critical illness. […] The cause is unclear in up to 80% of cases. Most foodborne illnesses are secondary to viral causes, with Norovirus being the most common. […] Campylobacter and nontyphoidal Salmonella are the most common causes of bacterial foodborne illness in the United States; other less common pathogens include Shiga toxin-producing Escherichia coli (STEC), Shigella, Cyclospora, Yersinia, Listeria, and Vibrio. […] Salmonella (nontyphoidal) infections are the most dangerous of the bacterial foodborne illnesses as they are most commonly associated with hospitalizations and deaths.

    Staphylococcal food poisoning results from eating food contaminated with toxins produced by certain types of staphylococci, resulting in diarrhea and vomiting. […] The diagnosis usually is based on the persons symptoms. […] The symptoms are usually all a doctor needs to diagnose staphylococcal food poisoning. […] A diagnosis of staphylococcal food poisoning may be suspected when other people who ate the same food are similarly affected and when the illness can be traced to a single source of contamination. […] To confirm the diagnosis, a laboratory must identify staphylococci in the suspected food, but this testing is not usually done because the results do not change treatment.

    Most people have mild illnesses, but some infections spread by food are serious or even life-threatening. Some people may need to be hospitalized, and some illnesses lead to other health problems, including meningitis, kidney damage, hemolytic uremic syndrome (HUS), which can cause kidney failure, arthritis, and brain and nerve damage. […] For some people, these health problems can last for weeks or months after recovering from a foodborne illness. For others, they never go away.
  • #1 Food Poisoning Tests and Diagnosis | Brown Chiari
    https://www.brownchiari.com/food-poisoning-tests-and-diagnosis/
    Food Poisoning Tests & Diagnosis There are several food poisoning tests medical professionals uses to diagnose food poisoning, usually being able to pinpoint exact causes, whether they be bacterial or viral. Some of these tests include the following: A stool sample may be needed for doctors to determine if the patient has consumed any contaminated food. Blood tests may be administered if symptoms are particularly severe, and can help rule out causes such as bacterial infections. Blood tests also help doctors determine if the patient is in need of treatment for dehydration. High-risk individuals may require a toxoplasmosis test. To learn more about this test, consult FoodSafety.gov’s section on high-risk groups. […] A physical examination can be used to identify symptoms of food poisoning that may need to be treated on an individual level, such as dehydration due to excessive vomiting. Weakness can be diagnosed from physical examinations and may help identify the specific type of illness. Blood pressure, pulse, and temperature are also measured to check for signs of illness, and can usually indicate dehydration. In some cases, a temperature may be taken to help identify the illness if the patient has a fever.

    Your health care provider will examine you for signs and symptoms of food poisoning, such as stomach problems, neurologic problems, and dehydration. […] Tests of your vomit, blood, and stool can sometimes identify the cause. […] In the case of botulism, your health care provider may request serum and stool test (to confirm botulinum neurotoxin) and electromyography (a test to measure electric impulses in the muscles) to confirm the diagnosis. […] Although brain imaging and lumbar puncture (spinal tap) results are normal in patients with botulism, they may be done to check for signs and symptoms related to central nervous system disorders.

    Ask the doctor or nurse to be sure that pathogen testing is done. […] Why is it important to know what is making me sick? Because there are more than 250 different viruses, bacteria, and parasites that can cause food poisoning, its imperative that accurate testing be conducted early, not only for your individual case, but to help investigate and prevent other illnesses in the event that your infection may be part of an outbreak. […] The most common lab tests are stool cultures which may take several days to render results. […] There are also faster laboratory tests that can reveal the cause of your illness within hours, instead of days. […] Ideally, both types of testing will be available to you: Traditional stool cultures which produce bacterial isolates, and Culture-Independent Diagnostic Tests. […] Your doctor or hospital should inform the local health department if testing detects a reportable pathogen. […] If foodborne illness is suspected, your doctor should submit appropriate specimens for laboratory testing.
  • #1 Diagnosis and Management of Foodborne Illness | AAFP
    https://www.aafp.org/pubs/afp/issues/2015/0901/p358.html
    None of the symptoms of foodborne illness is specific, so the clinician must consider the history, epidemiologic features, and objective findings to make an accurate diagnosis. Symptoms and time of onset can narrow the differential diagnosis and help identify a likely pathogen. […] The physical examination can help narrow the differential diagnosis, and vital signs can help determine the severity of volume depletion. […] Watchful waiting is often the most appropriate option in the initial diagnosis and management of foodborne illness; ancillary testing is usually not necessary. If testing is performed, stool culture can provide a definitive diagnosis of infectious diarrhea and is useful for outbreak identification. […] Most cases of acute infectious diarrhea are viral, and improper use of empiric antibiotics is associated with increased morbidity caused by adverse effects and Clostridium difficile colitis. Empiric antibiotics should be considered in cases of suspected foodborne illness only if the patient is febrile and has signs of invasive disease (e.g., gross hematochezia, leukocytes on fecal smear), if symptoms have persisted for more than one week or are severe (i.e., more than eight liquid stools per day), or if hospitalization may be required. […] If empiric treatment has not been initiated, antibiotic therapy may be indicated once stool culture, bacterial toxin, or microscopy results are available. Antibiotic therapy can shorten the duration of symptoms and may prevent bacteremia in older adults, newborns, and immunocompromised patients.

    Your doctor may be able to tell you what caused it after running tests. But they aren’t always necessary and don’t confirm every case. […] If your illness is severe or complicated, your doctor may run some of the following tests. […] Stool cultures are the most common lab test for food poisoning. Your doctor may order one if you have a fever, intense stomach pain, or bloody diarrhea, or if there is an outbreak that is being tracked. […] Blood tests may be ordered if your doctor thinks the infection has spread into the blood. […] Stool or blood tests can check for toxins, such as for botulism, which can be deadly. […] Imaging tests such as MRIs and CT scans aren’t often used in food poisoning cases. But they can help rule out other causes for your symptoms.

    Patient education: Foodborne illness (food poisoning) (Beyond the Basics) […] Microbial foodborne illness, sometimes called 'food poisoning,’ occurs commonly throughout the world, including in the United States. […] This topic review discusses the causes, signs and symptoms, and treatment of foodborne illness, along with ways to avoid it. […] Foodborne illness is usually diagnosed based on a person’s symptoms and history of what they have eaten in the prior week. […] When to seek help — If your symptoms are persistent or severe, if you have an underlying medical condition, or if there are worrisome signs or symptoms (temperature greater than 100.4°F/38°C, severe abdominal pain, inability to eat or drink, bloody stool, or vomit), you should see a health care provider for evaluation and treatment.
  • #2 Noninflammatory Gastroenteritis- Food Poisoning
    https://www.atsu.edu/faculty/chamberlain/website/tritzid/foodpoi.htm
    Food poisoning is a toxemia associated with the ingestion of preformed microbial toxins. It is NOT an infection. Since the toxins are ingested preformed and no microbial growth within the human is required, symptomology occurs rapidly, usually within 2-12 hours. […] In cases of gastroenteritis it is important to differentiate toxemia from infectious diarrhea. The key features are the rapidity of onset of symptoms following ingestion of contaminated food or drink, the lack of fever and the absence of fecal leukocytes. All of the toxemias result in symptoms occurring within 12 hours of toxin ingestion as compared to an incubation period of 24-72 hours for infections. […] Since the only fatal toxemia in this group is botulism, the emphasis should be on ruling out botulism in the diagnosis. The other toxemias are not severe and symptoms generally disappear within 24 hours. In fact the physician is hardly ever consulted in the mild toxemias. Presumptive diagnosis of botulism is made by the presence of a rapidly descending paralysis. A history of ingestion of home canned food or honey is helpful. Confirmative diagnosis is made by demonstrating botulinal toxin in the patients serum or feces or in incriminated food using a mouse toxin-neutralization test. […] Injectable therapeutics sometimes used include: 1. Trivalent (ABE) equine-origin botulinal antitoxin to neutralize unabsorbed toxin. 2. Guanidine hydrochloride to increase release of acetylcholine from nerve terminals. 3. 4-aminopyridine to increase release of acetylcholine.

    Food Poisoning Tests & Diagnosis There are several food poisoning tests medical professionals uses to diagnose food poisoning, usually being able to pinpoint exact causes, whether they be bacterial or viral. Some of these tests include the following: A stool sample may be needed for doctors to determine if the patient has consumed any contaminated food. Blood tests may be administered if symptoms are particularly severe, and can help rule out causes such as bacterial infections. Blood tests also help doctors determine if the patient is in need of treatment for dehydration. High-risk individuals may require a toxoplasmosis test. To learn more about this test, consult FoodSafety.gov’s section on high-risk groups. […] A physical examination can be used to identify symptoms of food poisoning that may need to be treated on an individual level, such as dehydration due to excessive vomiting. Weakness can be diagnosed from physical examinations and may help identify the specific type of illness. Blood pressure, pulse, and temperature are also measured to check for signs of illness, and can usually indicate dehydration. In some cases, a temperature may be taken to help identify the illness if the patient has a fever.

    None of the symptoms of foodborne illness is specific, so the clinician must consider the history, epidemiologic features, and objective findings to make an accurate diagnosis. Symptoms and time of onset can narrow the differential diagnosis and help identify a likely pathogen. […] The physical examination can help narrow the differential diagnosis, and vital signs can help determine the severity of volume depletion. […] Watchful waiting is often the most appropriate option in the initial diagnosis and management of foodborne illness; ancillary testing is usually not necessary. If testing is performed, stool culture can provide a definitive diagnosis of infectious diarrhea and is useful for outbreak identification. […] Most cases of acute infectious diarrhea are viral, and improper use of empiric antibiotics is associated with increased morbidity caused by adverse effects and Clostridium difficile colitis. Empiric antibiotics should be considered in cases of suspected foodborne illness only if the patient is febrile and has signs of invasive disease (e.g., gross hematochezia, leukocytes on fecal smear), if symptoms have persisted for more than one week or are severe (i.e., more than eight liquid stools per day), or if hospitalization may be required. […] If empiric treatment has not been initiated, antibiotic therapy may be indicated once stool culture, bacterial toxin, or microscopy results are available. Antibiotic therapy can shorten the duration of symptoms and may prevent bacteremia in older adults, newborns, and immunocompromised patients.
