  • Biological hazard
    A biological hazard is disease-causing microorganism or toxins that are found in some plants and fish. Exposure to these hazards or their inclusion in food can pose a health risk.
  • Blood Test
    A blood test is a scientific examination of a sample of blood, typically for the diagnosis of illness or for the detection germs such as bacteria or fungi. A blood test can show what type of germ is causing an infection, and help determine the course of treatment.
  • Blood Urea Nitrogen (BUN)
    BUN is a blood test that measures blood’s content of urea. When you eat protein, your blood carries some of it to your cells; and what’s left over is a waste called urea (which contains nitrogen). Healthy kidneys get rid of urea in the urine and when the kidneys fail, urea stays in the blood. So, the BUN test is used primarily to evaluate renal (kidney) function by measuring the urea found in the blood stream. It may also indicate liver disease or dehydration. In HUS, BUN level rises well above normal, indicating that kidneys are not filtering the blood properly.
  • Botulism
    Botulism is a rare but serious paralytic illness caused by a nerve toxin that is produced by the bacterium Clostridium botulinum.
  • Bradycardia
    Bradycardia is a slower than normal heart rate. The heart usually beats between 60 and 100 times a minute in an adult at rest. If you have bradycardia, your heart beats fewer than 60 times minute.
  • BRC

  • Bridgemanization
    See High Pressure Processing
  • BSE
    Bovine Spongiform Encephalopathy (Mad Cow Disease) BSE (Bovine Spongiform Encephalopathy) BSE is a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion. The normal prion protein changes into a pathogenic (harmful) form that then damages the central nervous system of cattle. BSE is also commonly called “Mad Cow Disease.”
  • Community-Acquired
    Community-Acquired MRSA or CA MRSA
  • CAFO

  • Carbon Monoxide in Food Packaging
    Using carbon monoxide in the processing of packaged meats and fish is in order to maintain the red, “fresh”-looking color and to extend shelf life. Although there is no data showing the ingestion of carbon monoxide is inherently dangerous, there are concerns that its use in packaging could pose potential dangers for the health and well-being of consumers. | Related: Carbon Monoxide in Food Packaging
  • Cardiomyopathy
    Cardiomyopathy refers to diseases of the heart muscle. These diseases have many causes, signs and symptoms, where a heart muscle becomes enlarged, thick, or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue.
  • Carrier
    A carrier is a symptomless individual who is host to a pathogenic microorganism and who has the potential to pass the pathogen to others.
  • Central Nervous System (CNS)
    The CNS is the brain and spinal cord. In HUS, central nervous system involvement means that the brain has become an organ compromised in some way by the disease.
  • Chem 10 or 20
    Chem 10 or 20 stands for a battery of chemical tests (Chem 10 = 10 tests; Chem 20 = 20 tests) performed on serum (portion of blood without cells). It is usually performed with a CBC to test for electrolytes, creatinine, BUN, etc.
  • Chemical Hazards
    Chemical hazards are substances such as cleaning solutions and sanitizers that can pose a health risk if they end up in food.

However, poultry slaughtered in China will not be allowed to be imported into the United States. | Related: Issues: Chinese Chicken
  • Chronic
    Chronic is the course of a disease persisting over a long period of time.
  • Coagulopathy
    Coagulopathy is the alteration of the mechanism that leads to normal clotting of the blood; may result in too much or too little clotting.
  • Coccus
    Coccus is the term used to describe any bacterium that has a spherical shape. It is one of the three distinct types of bacteria shapes. See bacillus (rod-shaped) and spirillum (spiral-shaped). The plural of coccus is cocci.
  • Colitis
    Colitis is inflammation of the colon; the usual symptoms are diarrhea, sometimes with blood and mucus, and lower abdominal pain.
  • Complete Blood Count (CBC)
    A CBC is series of tests in which the numbers of red blood cells, white blood cells, and platelets in a given volume of blood are counted. CBC also measures hemoglobin content and packed cell volume (hematocrit) of red blood cells, assesses the size and shape of the red blood cells (blood smear), and determines the types and percentages of white blood cells. Components of the complete blood count (hemoglobin, hematocrit, white blood cells, platelets, etc.) can also be tested separately when a doctor wants to monitor a specific condition.
  • Contamination
    Contamination is the presence of non-disclosed, unintended, and/or harmful substances or microorganisms in food.
  • Corrective Actions
    Corrective actions are to be taken when the results of monitoring at the CCP indicate a loss of control.
  • Creatinine
    Creatinine is a waste product (from muscle activity) found in the bloodstream that is excreted in urine. Like urea/nitrogen, creatinine is removed by healthy kidneys. In HUS, the creatinine level rises well above normal, indicating kidneys are not filtering the blood properly.
  • Creutzfeldt-Jakob Disease (CJD)
    CJD is a rare, degenerative, invariably fatal brain disorder. In the 1990’s a link was found in the U.K. between Variant CJD and Bovine Spongiform Encephalopathy (BSE or “mad cow disease”) due to meat from infected cattle entering the food chain.
  • Critical Control Point (CCP)
    A CCP is a step at which regulation can be applied and is essential to prevent or eliminate a food safety hazard or reduce it to an acceptable level.
  • Critical Limit
    Critical limit is a criterion which separates acceptability from unacceptability.
  • Cross-contamination
    Cross-contamination is the transfer of harmful bacteria. Harmful bacteria can not only be transferred from food to food, but also from hands to food.
  • Cryptosporidium parvum
    Cryptosporidium parvum is a single-celled animal (protozoa) that can cause foodborne illness.
  • Danger Zone

    The DATA Act (2013) is a bill that proposes amendments to the Federal Food, Drug, and Cosmetic Act (FFDCA) to enhance reporting requirements pertaining to the use of antimicrobial drugs in feed animals. This would aid both governmental and non-governmental groups in identifying trends in antibiotic resistance, designing appropriate interventions, and fine-tuning any antibiotic resistance efforts that have not proved effective. | Related: Issues: DATA Act
  • Dehydration
    Dehydration is a condition where the body does not have as much water and fluids as it should. Dehydration can be mild, moderate, or severe based on how much of the body’s fluid is lost or not replenished. When it is severe, dehydration is a life-threatening emergency.
  • Disease Surveillance
    Disease surveillance is an epidemiological practice by which the spread of illness is monitored in order to establish patterns of progression. The main role is to predict, observe, and minimize the harm caused by outbreak, epidemic, and pandemic situations, as well as increase knowledge about which factors contribute to such circumstances. A key part of modern disease surveillance is the practice of disease case reporting.
  • Disinfectant
    A disinfectant is a chemical that kills bacteria. Check that surfaces are cleaned of grease, dirt and food before you use a disinfectant. Chemicals that kill bacteria are sometimes called germicides, bactericides, or biocides.
  • DNA Fingerprinting
    DNA Fingerprinting is done to identify and evaluate the genetic information called deoxyribonucleic acid (DNA) in cells. It is called “fingerprinting” because, like fingerprints, it is very unlikely that any two people would have exactly the same DNA information. DNA is used to determine a genetic relationship between two people, and to identify organisms causing a disease.
  • Dosage (inoculum size)
    Here, dosage refers to the number of pathogenic microorganisms entering the host.
  • Dysentery
    Dysentery is inflammation of intestines with accompanying severe abdominal cramps, and frequent, low-volume stools containing blood, mucus, and fecal leukocytes.
  • Gram-positive Bacteria
    What is Gram-positive? Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. These bacteria have thick peptidoglycan layers in their cell walls that retain the dark stain, differentiating them from Gram-negative bacteria. Gram-positive bacteria, such as Staphylococcus, Streptococcus, Enterococcus, Listeria, and Clostridium are responsible for a large proportion of serious infections worldwide.
  • Peptidoglycan
    The main component in the cell wall of most bacteria is called peptidoglycan.
