Study Notes
- Food contains microorganisms, making food safety and awareness crucial for preventing food-related illnesses.
- Microbial foodborne diseases are a widespread global issue that reduces economic productivity.
Food-Borne Illness Defined
- The WHO defines foodborne illness as any infectious or toxic disease caused or thought to be caused by consuming contaminated food or water.
- Foodborne diseases range in severity from mild gastrointestinal issues to life-threatening conditions like botulism.
- Contaminated food may appear, taste, or smell normal.
Scope of Definition
- Food poisoning mainly involves gastrointestinal symptoms like diarrhea or vomiting.
- It also includes illnesses with symptoms beyond the gastrointestinal tract, such as Listeriosis, which can have severe consequences.
- Illnesses caused by ingesting toxins in food are included, but allergies and food intolerances are excluded.
Definition of "Outbreak"
- An outbreak involves two or more linked cases with a common exposure, experiencing similar illness or proven infection, which can be general or confined to one household and may occur locally, nationally, or internationally.
- A general outbreak affects members of more than one private residence or residents of an institution.
Types of Food Poisoning
- Infections, caused by ingesting food contaminated with microbes.
- Intoxications, caused by ingesting food contaminated with toxins.
Infections
- This is caused by ingesting microbes in food, allowing pathogens to grow and increase in number, leading to infections.
- The contaminated food acts as a carrier, supporting pathogen growth.
- Examples include: Salmonellosis, Bacillus cereus Gastroenteritis, Escherichia coli infection, Shigellosis, Vibrio, and Beta Haemolytic streptococcal infection.
Infections due to Food Borne Parasites
- Amebiasis: An intestinal illness from food/drink contaminated with Entamoeba histolytica, which can cause bloody diarrhea and spread to other organs.
- Trichinosis: An infection caused by a roundworm from undercooked meat, leading to stomach pains and abdominal cramps.
Foods Commonly Associated with Food-Borne Illness
- Top four implicated food types are meat and meat products, poultry, eggs and egg products, and seafood.
- Other foods include milk and milk products, fruits and vegetables, confectionery, and cereals and pasta.
Transmission of Food-Borne Illness
- Soil and Water
- Plants and animals
- Raw to processed food (cross-contamination)
- Person to Food
- Person to Person
Factors Contributing to Food Poisoning Outbreaks
- Preparation too far in advance.
- Storage at ambient temperature.
- Inadequate cooling.
- Contaminated processed food.
- Undercooking.
- Contaminated canned food.
- Inadequate thawing.
- Cross-contamination.
- Food consumed raw.
- Improper warm handling.
- Infected food handlers.
- Use of leftovers.
- Extra-large quantities prepared.
Impact on Humans
- It is hard to assess numbers affected due to under-resourced monitoring and underreporting.
- The CDC estimates that annually, 1 in 6 Americans (48 million people) get sick, 128,000 are hospitalized, and 3,000 die from foodborne illness.
Increasing Risk Factors
- Changes in farming practices.
- Increased international trade.
- Large-scale food production.
- Increased international movement of people.
- Changing consumer preferences/lifestyles.
- New and more virulent strains emerging.
- Increasing numbers of at-risk people.
- Employee turnover/training issues.
