September is nationwide Food Safety education and learning Month, and also we want to highlight techniques for implementing more secure food practices. The CDC has reported that 48 million people per year acquire sick indigenous a foodborne illness, countless of which are preventable. The is necessary for food business professionals to be aware of the primary types of food security hazards, and also the ideal methods of prevention.

You are watching: The three types of hazards that make food unsafe are

Food safety Hazards

There are 4 primary categories of food safety perils to consider: biological, chemical, physical, and also allergenic. Understanding the risks linked with each can dramatically reduce the potential that a foodborne illness. Each have their own distinctive characteristics, yet all can be avoided v a robust food safety monitoring system (FSMS).

Biological Hazards

Biological dangers are identified by the pollution of food by microorganisms. Found in the air, food, water, animals, and in the human being body, these extremely tiny organisms space not naturally unsafe – many provide benefits to our anatomy. In spite of this, foodborne condition can happen if harmful microorganisms do their means into the food we eat. There are several types of microorganisms, every of which deserve to negatively affect health: bacteria, viruses, and parasites.


Bacteria nests on a petri dish

There space a selection of components that influence dangerous microorganism growth, including temperature, pH levels, and moisture the the food. The USDA has actually coined a term for the temperature range that encourages bacterial growth: the peril Zone. This temperature range, 40° F – 140° F, enables bacteria to flourish most rapidly, practically doubling the number in 20 minutes. In addition, the pH level of a food, or that acidity, can accelerate growth. Foods that are less acidic, such as milk, have tendency to foster bacteria at higher rates than an ext acidic foods, favor lemon juice. Microbes favor warmer, wetter environments, which make moist foodstuffs hotbeds for virus growth.


Biological peril Examples

Biological Hazard

Commonly uncovered in


Eggs, poultry, meat, unpasteurized milk or juice, cheese, fruits and vegetables, spices, and also nuts


Produce, shellfish, ready-to-eat foods


Raw and also undercooked poultry, unpasteurized milk, contaminated water

E. Coli

Undercooked ground beef, unpasteurized milk or juice, raw milk cheeses, life fruits and vegetables, contaminated water


Ready-to-eat deli meats and hot dogs, unpasteurized milk or juice, raw milk cheeses

Clostridium perfringens

Beef, poultry, gravies

Biological hazard Prevention

The best means to prevent organic hazards native affecting client is to implement durable processing and also storage strategies. Kill procedures used before packaging is necessary, such as cooking thoroughly or pasteurization the milk and also juices. Use of packaging technologies throughout processing like vacuum sealing hinders bacter growth. Ideal temperature management for warehouse can considerably reduce microbe growth. Finally, effective sanitation methods throughout the circulation chain will minimize cross-contamination that food products.

Chemical Hazards

Chemical risks are identified by the visibility of harmful building materials that have the right to be uncovered in food naturally, or unintentionally included during processing. Part chemical hazards include naturally occurring chemicals, such together mycotoxins, intentionally added chemicals, including the preservative sodium nitrate, and unintentionally added chemicals, favor pesticides.

Chemical hazards Examples

Chemical Hazard



Produced by fungi and can be toxic to humans and also animals. Castle are formed by moulds which prosper on crops and also foods under details conditions.

Natural Toxins

Biochemical compounds produced by tree in response to specific conditions or stressors.

Marine Toxins

Decomposition or microscopic naval algae built up in fish and shellfish.

Environmental Contaminants

Accidentally or deliberately get in the environment. Typically manufactured for industrial use.

Food Additives

Any chemical substance the is added to food throughout preparation or storage.

Processing-induced Chemicals

Undesirable chemicals have the right to be formed in particular foods during processing together a an outcome of reactions in between compounds that space natural components of the food.

Pesticides/Agricultural Products

Used to control, destroy, or loss a pest, or to minimize the impacts of a pest.

Veterinary drug Residues

Used in food-producing pets to regulate and/or prevent disease in the animal.

Chemical hazards Prevention

Similar to preventing biological hazards, proper cleaning procedures and also sanitation requirements are the ideal methods of prevention. Training employee to follow strict guidelines is crucial in staying clear of a chemical hazard. Additionally, limiting the usage of chemistry to those normally recognized together safe (GRAS),and ensuring that chemicals space stored in designated locations separated from food products.

Physical Hazards

Physical dangers are foreign objects that are found in food products. They are either naturally found in the particular item, such as stems in fruit, or not normally part of the food item, such together hair or plastic. Unnatural physical hazards are generally more dangerous come health, whereas herbal physical hazards deserve to be harmless.


Recently, sewing needles were maliciously inserted in strawberries throughout Australia

Physical dangers Examples

Physical Hazard



Insects, hair, steel fragments, pieces of plastic, hardwood chips, and glass


Stems in blueberries, microscopic airborne debris, dirt on potatoes, or minute insect pieces in figs

Physical hazards Prevention

Prevention of physical hazards emphasis primarily top top thorough investigate of food, and strict follow to food safety regulations, such as danger Analysis an important Control point (HACCP) questioned below. Establishments can likewise take proactive measures in removed the potential that a physical hazard. Irradiate bulbs, because that instance, have the right to be produced using different materials. Acrylic is both lighter and stronger than glass, and tends come shatter into larger, blunter fragments than glass.

Allergenic Hazards

The final, and perhaps the most deadly, are allergenic hazards. Allergies are the 6th leading reason of chronic illness in the U.S., with much more than 50 million people suffering from allergies each year. Allergic reactions occur when the human being body produce an abnormal immune an answer to certain proteins found in food.



Allergenic Hazards

Allergenic Hazard

Commonly discovered in


Butter, cheese, cream, milk powders, and yogurt


Cakes, some meat products, mayonnaise, mousse, pasta, quiche, sauces, and also foods brushed with egg


Breads, biscuits, crackers, desserts, ice cream, marzipan, nut oils, sauces, and curries or stir fries


Desserts, ice cream cream, sauces, and vegetarian products


Baking powders, batter, breadcrumbs, brea, cakes, couscous, pasta, pastries, sauces, soups, and also foods dusted with flour


Fish sauces, pizzas, relishes, salad dressings, share cubes, and Worcestershire sauce


Shrimp paste, and also curries or salads


Unfortunately there is no way to stop allergies, yet it is possible to reduce the risk of an allergy reaction. So lengthy as companies adopt proper sanitation techniques and also present potential allergenic ingredients obviously ~ above product packaging, allergic reactions will be minimized. Staying clear of an allergic reaction drops primarily on the consumer, however they can only do so effectively if businesses execute their part with reliable sanitation and labeling of ingredients.

Regulations and also Laws

Regulatory bodies including the Food and Drug management (FDA) and the United claims Department of farming (USDA) have implemented laws that aid minimize food safety risk and also ensure safer food safety practices. In doing so, food safety techniques have become significantly more robust and effective.

Hazard Analysis crucial Control allude (HACCP)

HACCP, implemented in 1997, changed food safety and security methodology to it is in science-based together opposed to typical “sight, smell, and also touch” inspection. HACCP’s core values provides a means to analyze biological, chemical, and physical hazards along the it is provided chain. This avoids outbreaks before they can take place rather than responding come them ~ the fact, and also helped to accelerate an innovation used to control food safety. Foodborne illnesses reduced dramatically together a an outcome of HACCP.

Food safety Modernization action (FSMA)

Similar come HACCP, FSMA has enabled added methods of avoiding food contamination. The Sanitary transportation of Human and Animal Food has actually three methods of avoiding foodborne illness: vehicles and transportation operations should validate temperatures in transit, staff have to be trained appropriately to prevent methods that create food safety risk, and brand-new record keeping requirements produced efficient mechanisms to demonstrate proper temperature control. With proactive monitoring of food safety, distributors are much better equipped to prevent foodborne illness.
