Types of food contamination

Let Everyone know

Food contamination is indeed a worldwide health hazard, with one out of every ten people being unwell each year as a result of tainted food. As a result, businesses are required to maintain the greatest levels of food safety.

Failure to verify that all foods are suitable to eat might have disastrous consequences. It’s crucial to understand what the possible risks are when it relates to eating, particularly if you are prepping or providing meals for someone else. Knowing how food can get contaminated allows you to take preventative measures.

Food contamination causes food-borne sickness and its business-destroying relative, a food-borne illness epidemic. Food contamination occurs whenever something shouldn’t be in food, and it makes the food unhealthy to eat.

From the farm or the fisheries to the dining table, there are various steps. The food production chain is what we call these phases. Contamination can happen anywhere in the supply chain, including during manufacturing, processing, distribution, and preparation. A portion of food may have been mismanaged in numerous ways along the food supply chain by the time it causes disease.

Once the food has been contaminated, further mismanagement, such as undercooking it or leaving it out on the counter at an unsafe temperature, can increase the risk of foodborne disease. In food kept at room temperature, many bacteria multiply fast; a small number can swiftly increase to a high number in only a few hours.

Heating up or simmering food after it has been kept at room temps for a long period does not always make it safe since certain micro-organisms release poisons that are not eliminated by heat.

There are two ways in which food may get contaminated,

Accidental: Accidental contamination is caused by unintentional human activity, unplanned events, and human error. Breaking machinery or equipment can result in things like a piece of plastic becoming mixed into a cake or metal shavings from a damaged machine part. It may also result in inappropriate handling techniques. Because individuals are more likely to be aware of the occurrence, inadvertent contamination is more likely to be addressed before the product is released. Even if the item has not yet been delivered to clients, a risk assessment must be completed.

Intentional: Intentional contamination, sometimes known as food fraud, is an increasing problem. It is a criminal crime that relates to intentional actions of contamination. This may happen at any time, and the culprit might be a stranger or a coworker.

What are Types of Food Contamination?

Contamination of food may have major effects on both consumers and corporations in the food industry. It has the potential to endanger customer health and safety, as well as negatively impact a company’s brand if someone is injured there.

While the majority of people assume there are only three forms of contamination, there are five to be aware of. It’s critical to understand these five sorts in order to safeguard your clients’ health and your company’s image.

  • Chemical Contamination
  • Natural and man-made Contamination
  • Physical Contamination
  • Microbial Contamination
  • Allergenic Contamination

Chemical Contamination

Chemical contamination occurs when food is affected by a chemical. It’s the most difficult type of contamination to handle because it can cause acute poisoning as well as long-term disorders. Chemical pollution can cause a wide range of symptoms. In most cases, the consumer will have mild gastroenteritis, but chemicals in food can be fatal in rare circumstances.

In recent years, there has been a growing interest in the impacts of chemicals in our food on consumer health and well-being. Long-term exposure to low doses of carcinogens, for example, has been proven in studies to raise the risk of a cancer diagnosis.

Natural and man-made Contamination

Natural and artificial (Man-made) chemical contamination are the two forms of contamination. The presence of chemicals that occur naturally in food is referred to as natural chemical contamination. These are controlled, and the government has set minimum standards for those deemed to be dangerous. As a result, food producers and manufacturers must ensure that safeguards are in place to ensure that products do not exceed these limits. Food is polluted with a chemical that is not a natural by-product of the food when it is artificially infected. This might contain cleaning and disinfection chemicals, fertilizers, and insecticides, among other things.

The following are some of the most prevalent examples of man made chemical contamination:

  • Disinfectants and cleaning supplies.
  • Fruit and vegetables that haven’t been washed.
  • Use acid and salt-resistant utensils.
  • Chemicals are released as a result of the usage of non-safe polymers.
  • Chemicals for pest control.
  • Antibiotics.
  • Medications that reduce inflammation.
  • Corticosteroids
  • Heavy metal is a genre of music.

The following are some of the most effective ways to avoid man made chemical contamination:

  • Chemicals, especially cleaning products, should always be kept apart from food.
  • When at all possible, keep food covered.
  • Make sure chemicals are labeled correctly.
  • Poison should not be used in the same room as food that is being created or cooked.

Physical Contamination

Food that has been tainted by an external element is known as physical contamination. Finding foreign items in our food is unsettling, and it leads customers to be concerned. Food that has been tainted by a physical item can cause significant harm including choking. Furthermore, the object might be contaminated with germs, resulting in microbiological contamination.

Glass, hair, metal, jewelry, dirt, and fingernails are the most prevalent items that contaminate meals. Physical contamination of food can also come from the surroundings, such as plaster, paint flakes, and screw fasteners, as well as the facility and equipment you’re utilizing. Physical contamination may also arise as a result of packing concerns, such as staples, twine, polythene, and cardboard.

Some physical contamination, such as insects in fruit and vegetables or bones in boneless fish, can occur naturally. Regardless of whether it is a natural component of the food, businesses must figure out how it got there and how to prevent such occurrences from happening again.

Microbial Contamination

The most prevalent cause of food illness is microbial contamination, also known as biological contamination. Microorganisms, bacteria, viruses, mold, fungus, and poisons are examples of hazardous pathogens found in food. Food spoilage or waste is the major source of food-borne disease and food poisoning, and it is the most prevalent cause. Chilling food causes pathogens to become dormant, but it does not always stop germs from growing. Foods should be completely cooked to the correct temperature to guarantee that bacteria are killed throughout the cooking process. Many microbial poisons, however, are heat resistant, therefore ruined food should not be cooked and ingested.

Norovirus, salmonella, listeria, e.coli, and campylobacter are the most prevalent food-borne infections, with symptoms ranging from moderate stomach troubles to deadly and long-term disorders.

Direct or cross-contamination might result in microbial contamination. Direct contamination occurs when germs that have already been created in the food reach dangerous levels. Bacteria and poisons present in rotting meat are a good illustration of this. Cross-contamination occurs when bacteria from other sources enter food and grow to dangerous levels.

Some foods are thought to have a significant microbial contamination risk. With the supply of food, water, and neutral pH, the nature of these foods creates an ideal habitat for bacteria to grow. Here are a few examples:

  • Meat.
  • Poultry.
  • Rice.
  • Dairy products.
  • Cooked and raw eggs.
  • Seafood.
  • Unpasteurized juices.
  • Prepared fruits and vegetables.

Allergenic Contamination

The process by which the body responds to a certain meal causes a food allergy, with the body’s defense system mistaking the item for a threat. Around 5,500 people in the UK visit the hospital each year as a result of an allergic response, a statistic that has been rising since the 1980s. In fact, the number of persons admitted to hospitals with anaphylaxis in the UK has increased by 615 percent in the 20 years prior to 2012. This is a life-threatening allergic reaction in which the body produces histamine to combat the allergen. Anaphylaxis is a life-threatening condition that requires immediate medical intervention.

Because even tiny quantities of an allergen can induce such a severe reaction, all organizations that manufacture food have an obligation to be mindful of the hazards of cross-contamination. As a result, there are severe rules in place that businesses must follow in order to protect client safety. Companies must implement a stringent strategy to avoid cross-contamination of the 14 most common allergies.

Cross-contamination can happen at any point in the food production process, including harvesting, slaughtering, subsequent agricultural production, shipping, warehousing, redistribution, preparing, and consumption. Some firms are unable to prevent trace allergen contamination from entering food given the nature of their company. They will have to put a precautionary allergy warning on their packaging if reasonable improvements cannot be made.

Businesses must take adequate precautions and have a strategy to prevent allergy cross-contamination. The following are some possible steps:

  • If a food contains any of the 14 allergies preidentified, it should be properly labeled.
  • Hands should be cleaned regularly and in an appropriate manner.
  • After each usage, thoroughly clean all equipment.
  • Separate equipment should be used for food containing allergies.
  • Swabs should be used to check for allergies.
  • Separately store food with allergies in storage containers that are properly labeled.

How do we know if the food is contaminated?

The ideal method is to utilize your sight, nose, and touch; these three senses will typically reveal the solution. Look at the dish to see if the color is normal or if it has discoloration, feel the item to see if it is sticky to the touch, and finally smell the thing to see if it is ruined. Particularly seafood. Use a food thermometer to ensure that a refrigerated item is in the safe food zone, which is below 40 degrees.

When smelling ruined food, I’ve always been fortunate to have a gag response, which is always a dead giveaway that the product shouldn’t be ingested. Chemical, microbial, physical, and allergenic contamination are all possible sources of contamination in food. However, you must ensure that these pollutants do not compromise the safety of your meals. Contamination can cause food poisoning, damage, and allergic responses, but you can help to avoid them all by adopting safe operating procedures.
