Food contaminated by bacteria, viruses and parasites can make you sick. Many people have had foodborne illness and not even known it. It's sometimes called food poisoning, and it can feel like the flu. Symptoms may include the following:
Symptoms can start soon after eating contaminated food, but they can also occur up to a month or more later. For some people, especially young children, the elderly, pregnant women and people with weakened immune systems, foodborne illness can be very dangerous.
Public health experts estimate that there are 11 to 13 million cases of foodborne illness in Canada every year. Most cases of foodborne illness can be prevented by using safe food handling practices and using a food thermometer to check that your food is cooked to a safe internal temperature!
Campylobacter jejuni (C. jejuni) is a bacterium commonly found in the intestines of poultry, cattle, swine, rodents, wild birds and household pets like cats and dogs. It has also been found in untreated surface water (caused by fecal material in the environment) and manure. C. jejuni is the most common Campylobacter associated with human illness. Humans may develop an illness call campylobacteriosis if they consume food infected by C. jejuni bacteria.
Symptoms may include fever, headache and muscle pain, followed by often bloody diarrhea, stomach pain, cramps, nausea and vomiting. More severe illness such as septicemia can occur in immunocompromised individuals.
Further complications could include Guillain-Barré Syndrome, meningitis, septicemia, urinary tract infections and reactive arthritis (painful inflammation of joints which can last several months).
Symptoms of infection usually occur within 2 to 5 days after the bacteria have been ingested, but can occur up to a month later, and usually last no longer than 10 days. It takes most people anywhere from a few days to a few weeks to recover.
Raw poultry can be contaminated with the C. jejuni bacteria. The common route of exposure is through cross-contamination which could occur during food storage and preparation. For instance, the pathogen when present in raw poultry could be deposited on and contaminate cutting boards, kitchen counters, utensils and other surfaces (including human hands) while in contact with the contaminated raw food. If these surfaces are not properly washed and cleaned before they are used for handling ready-to-eat food, e.g., food that was already cooked, they could contaminate it with bacteria. People may also develop C. jejuni infections when they drink raw milk or untreated water.
Campylobacter jejuni may also be transmitted from hands that were not washed properly after petting infected cats and dogs (or farm animals) whose coats could contain infected fecal matter.
