Food contamination happens when enough of certain types of bacteria or their toxins are present in food. These bacteria or toxins can cause a serious illness called food poisoning. That’s why food quality assurance is of paramount importance; at AsureQuality, you’re guaranteed quality assurance when it comes to food so you can eat without worries.

Food safety is a major issue worldwide. Luckily, you can help to protect yourself and your family by following the 4 C’s of food safety: Clean, Cook, Cross-Contaminate and Chill.

Pathogens

The microorganisms that cause food contamination are called pathogens. These organisms include viruses, bacteria, fungi, and protozoa.

Infection by pathogens is a common cause of disease in people. They are microscopic organisms that can spread from person to person through skin contact, body fluids, and other routes of entry. They can also be spread through airborne particles.

Bacteria are one of the most common types of pathogens that can make people sick. They are tiny microorganisms that can thrive in a variety of conditions, including high water or moisture content and neutral acidity (pH).

Some bacteria multiply exceptionally quickly. For example, one single cell can grow into two million in seven hours, making them a deadly threat to human health.

Other pathogens can survive in a range of temperatures and salt concentrations. This makes them especially dangerous to people with immune problems. For example, Listeria monocytogenes can live in cold and damp environments for long periods of time, contaminating food and causing serious infections.

Fungi are another type of pathogens that can cause disease in humans and animals. These microorganisms are usually single-cell organisms that can infect other organisms to survive and reproduce. They can also cause infection in plants and food crops.

Many fungi have the ability to use signals in their bodies to detect impending dangers. This allows them to adapt and survive against threats, such as heat, chemicals, or pressure.

Other fungi are capable of developing specific proteins to protect themselves from disease-causing bacteria. This is known as a virulence mechanism. These changes can lead to the evolution of a new pathogen that is more dangerous than its predecessor. This is sometimes known as the host jump effect.

Chemicals

While microorganisms are the most common type of food contamination, chemicals can also pose a serious threat to health and safety. They are typically introduced by human activities, and can come from a variety of sources.

Some of these chemicals are found naturally in the environment, while others are manufactured by chemical companies. These substances can be harmful to human health and the environment if they are not used properly, and some of them have even been banned from use entirely in certain countries.

There are many types of chemicals, from dyes to preservatives and pesticides, that can end up in your food. Some of them are added during production and processing, while others are added during packaging.

These contaminants can be harmful to your health if they are not monitored properly and not removed before they enter the food supply. They can have both immediate and long-term effects, ranging from mild gastric problems to death.

Some of the most harmful chemicals in our food include pesticides and heavy metals. These can be found in our fruits and vegetables, and can cause a variety of health issues.

To avoid this type of contamination, make sure you wash your produce and follow the manufacturer’s instructions on how to remove the pesticides. You can also choose fresh fruits and vegetables from suppliers who have a good food safety program in place.

The levels of chemical contaminants in our food can be regulated by law, or by voluntary initiatives. These limits are determined based on toxicity studies of the chemicals and their impact on living organisms.

Metals

The presence of metals such as arsenic, cadmium, mercury and lead in food can be harmful to consumers. They can cause severe health risks such as brain damage and cancer.

Heavy metals can be found naturally in the environment, as well as as pollutants from industrial and other human activities. They can also be deposited on the earth’s surface due to geological activity and natural erosion of soil.

Exposure to these substances occurs mainly through the diet and in some cases through breathing or drinking water. This is why it is so important to control the occurrence of metals in the food chain.

In order to protect people’s health, regulatory bodies set maximum levels for certain contaminants, in particular for lead, cadmium and mercury. These levels are specified in Regulation EC 1881/2006 and in Directive 96/23/EC on monitoring of residues of chemical elements in foods of animal origin.

A high sensitivity technique for testing for heavy metals is ICP-OES (Inductively Coupled Plasma – Oxidation Electrochemical Spectrometry). However, this expensive method is not the best way to assess contaminant levels in a food sample, as it can lead to false negatives.

Alternatively, a less expensive and more sensitive option is GF-AAS (Glass-Fibre Amine-Assaying System). This method allows you to test for metals in a small volume of sample with very high sensitivity.

A wide range of studies has demonstrated that metals can be accumulated in the body in low concentrations and that exposure to these substances is linked to many diseases and conditions. These findings have encouraged governments around the world to set strict limits for these toxic metals in order to reduce the risk of harm to people.

Molds

When molds grow on food, they can become a choking hazard and may be a source of biological contaminants. A mold spore, for example, can carry bacteria that can cause serious foodborne illness when consumed.

Molds are fungi that live on organic matter and produce reproductive cells called spores that fly through the air. The spores are very small and lightweight, so they can easily spread through the air.

Most molds need moisture to grow and they can often be found in damp areas such as refrigerators, shower rooms and after water pipe leaks or floods. In these situations, molds produce a high number of spores that can be inhaled by people who are living or working in the affected building.

In addition to causing property damage and deteriorating indoor air quality, molds can also lead to health problems. For instance, some molds can eat through foods and produce harmful toxins known as mycotoxins.

However, there are many molds that are harmless to human health. These include those that produce a white powdery substance called mycelial fungal hyphae and those that secrete hydrolytic enzymes to break down complex biopolymers such as starch, cellulose and lignin.

For this reason, it is important to wash all contaminated food items thoroughly and discard them as soon as possible. This will prevent the mold from spreading to other parts of the food item and causing further contamination.

The best way to avoid mold is to wash all food thoroughly and store them in a clean, dry place where they won’t get wet. This means keeping fresh fruits and vegetables in the refrigerator, avoiding storing half-used cans of food in the freezer and using plastic wrap to keep salads and cut fruit moist while they’re in the fridge.

Parasites

Parasites are a group of tiny organisms that live and grow in your body. They can be inside your organs, in your bloodstream or even on your skin and hair. Most parasites need their host to survive, but some can be harmful and make you sick.

Infections with parasites are common around the world and affect many different people. They cause symptoms that range from itching and irritability to insomnia and weight loss.

These diseases are a problem for all types of people, but especially the elderly and those who are malnourished or weakened by illness. They can be very hard to diagnose and treat.

Most parasites are transmitted from one host to another through air, contaminated water, or feces. They can also be transferred to people by touching infected animals, such as pigs.

If you are unsure whether you have a parasite infection, you should get a stool test. The tests can be done by your doctor, or you can order them online.

The parasites that affect humans are mainly bacteria, viruses, and protozoa. They are very small and can be hard to see with the naked eye.

Viruses, for example, are microscopic. They can be found in the bloodstream and may live for a long time in the bloodstream. They can be found at high levels during the acute (fast-moving) phase of an infection, then lower levels later in the chronic (slow-moving) phase.

Infected parasites can be passed from person to person in a number of ways, including through unwashed hands after using the restroom, by handling or touching infected animals, and by traveling overseas. In addition, certain parasites can be transmitted through the bites of mosquitoes.
