The food industry is a very complex part of a community. Several factors including biological, physical, and chemical objects are combined and come in contact with the processing of food. This very essence of the foodservice industry tells us that food safety hazards will never be absent from the whole food chain. These hazards will always be present in any food business. They can only be prevented, minimized, or eliminated by implementing preventive and control measures.
Food safety hazards are the main causative agents of foodborne illnesses. They are capable of causing diseases or injuries to consumers which can be mild or life-threatening. Food business owners are responsible for keeping these food safety hazards controlled by ensuring that employees are well-equipped with proper knowledge on food safety. All food safety management systems are built around the objective of controlling these hazards.
WHAT WE'LL COVER:
Food safety hazards are any agent found within the food supply chain that can contaminate food materials and cause unwanted health conditions to the public. These hazards contaminate raw materials and finished products as a result of exposure to potential sources. Contamination by food safety hazards can occur anywhere in the food supply chain including harvesting, transit, processing, packaging, delivery, serving, and even storage.
Food safety hazards can either be innately present in foods or can be introduced from external sources. Different foods have their affinity to particular food safety hazards. An example would be the high affinity of peanuts to potent fungal toxins such as aflatoxin. Since this type of food safety hazard can be lethal with long-term exposure, strict food safety laws have been established for them. Additionally, chemical food safety hazards such as acrylamide are common indicators of temperature abuse for heated products and can cause adverse health effects.
Any type of food safety hazard has the potential to cause significant foodborne illnesses and injury especially for immunocompromised individuals such as the elderly, children, and pregnant women. All food handlers must be aware of the basic information about food safety hazards. This task is the first step in knowing how to address them properly. Each type of food safety hazard would need a specific food safety practice to control them.
Food safety hazards are subdivided into 4 different categories. Each category describes the nature of the food safety hazard and gives food handlers an idea of the proper practices needed to control them. Food safety hazards can be any of the following:
These food safety hazards constitute all of the agents that can cause foodborne illnesses or allergic reactions to consumers. Depending on factors such as the level of contamination, the likelihood of occurrence, and the potential damage it can cause, these food safety hazards can mildly or significantly affect public health.

Here is a more in-depth discussion of these food safety hazards:
Biological hazards are food safety contaminants that originate from living organisms that include pathogenic bacteria, fungi, yeasts, viruses, and parasites. These hazards can significantly affect the health of the public by causing foodborne illnesses that can range from mild to very severe. They are different from beneficial microorganisms used in fermentation or as probiotics. Biological hazards may also include natural toxins produced by these pathogens. Biological hazards are the most common causes of outbreaks in the food industry.
Food safety hazards such as bacteria and viruses can easily be transferred to food from cross-contamination. These hazards are also dependent on factors surrounding the host food such as:
Depending on the presence of these factors, the surviving microbiological hazards may vary. Some dangerous pathogens such as the Clostridium botulinum, which is known for its potency to kill consumers, can only survive in conditions without oxygen and low acidity such as in canned goods.
These conditions also determine the rate at which pathogenic hazards multiply. An example of this condition would be the principle behind the temperature danger zone which is 40°F and 140°F (5°C and 60°C). This temperature range is where most pathogens thrive best and can easily spoil food. Precautions for biological hazards include proper handling practices such as handwashing, regular cleaning, chilling of foods, and thorough cooking.
Biological hazards are very common in the food service area and food production sites. Their presence is even larger during the harvesting of raw materials. Here are a few common sources of biological hazards within the food supply chain:

Hazards under this category are chemical substances that are naturally occurring or added to foods that can cause foodborne illness or injury to humans. Natural chemical hazards are harmful substances that are innately present in foods. A good example of natural toxins is saponins from legumes. This compound is a natural part of the toxic defense of plants against harmful microorganisms and insects. This compound can be risky when ingested in high amounts. As such, legumes are pretreated before cooking or consumption.
In addition to naturally occurring chemical hazards, intentionally added ones such as food additives and preservatives are also present in the industry and can be considered chemical contaminants. These additives and preservatives become hazardous when used in excessive amounts or without proper labeling. On the other hand, chemicals such as pesticide residues, fertilizers, antibiotics, machine oil, and heavy metal compounds are considered unintentional chemical hazards and have serious effects on humans when ingested.
As mentioned, chemical hazards can be naturally present in materials, intentionally added, or unintentionally introduced to foods. In some cases, chemical hazards can also occur as a result of processing abuse, especially in heating treatments. Below are some of the common sources of chemical hazards in the food industry:

Physical hazards are any foreign objects or extraneous material that can contaminate food and cause injury or act as a precursor for the growth of pathogens. Physical hazards can be objects such as glass shards, metal fragments, bones, stones, or other debris that can cause cuts, choking, and other serious injuries to the consumer.
This type of hazard can naturally come from food materials such as bones from meat, stems from fruits, or shells from seafood. Other types of physical hazards can come unnaturally from broken production materials including plastics, glass, textile, or jewelry. Contaminants such as nails and hair can also come from food handlers. Physical hazards can sometimes be prevented through physical observations and inspection. At times during large volume productions, an automatic detector can be used.
There are a variety of sources of physical hazards in the production line. They can come from pests, machines, or the food handlers themselves. Detection of physical hazards is important as it can also attract or spread other types of hazards. Here are some common sources of physical hazards:

Allergens are food safety hazards caused by proteins that the immune system of some individuals mistake as a dangerous foreign matter and cause dangerous reactions. These proteins are natural parts of some foods. Allergenic reactions can cause symptoms that include itching in the mouth or other parts of the skin, hives, swelling, abdominal pain, nausea, and vomiting. In more serious cases, allergens can even cause anaphylaxis which is a severe allergic reaction that causes the blood pressure to drop and for the airways to tighten and block breathing.
In the US, more than 50 million citizens have been reported to have experiences allergies each year. The early detection of allergens is a must for individuals. Because the results can be life-threatening, food businesses must be wary of the food they serve and properly communicate with consumers the potential allergens present. Notes on the menu or a food allergen poster can be helpful for food businesses. In the US, there are 8 common food allergens, whereas, in the UK, 14 are recognized.
*Additional allergens in the UK
By law, food establishments and manufacturers are required to declare any food allergen present in a food product. Indications may be added on packaging labels or menus as long as they are visible and easy to spot. There is no way of telling whether a consumer has food allergies by visual observation. As such, it is the responsibility of a food business team to inform them of the potential risks in your food products.
To better understand more about food safety hazards, here are a few frequently asked questions about this topic:
A part of the most prominent food safety management systems such as the Hazard Analysis Critical Control Points (HACCP) system is the proper identification of food hazards. Identification and analysis are proactive approaches in addressing the potential effects of these safety hazards. The basis for hazard identification must be from established and reliable resources as public health depends on them.
Below are different ways and basis that you can use in identifying hazards:
Over the years and as an effort of the scientific community to keep the food industry safe, related literature on common and more complicated food safety hazards has been studied. These hazards are mostly categorized based on the type of food being prepared. These sets of information contain minimum and maximum residue limits that are allowed for a particular food safety hazard as well as appropriate handling practices to address them.
Peer-reviewed scientific articles on common food safety hazards are normally available online. Alternatively, you can also consult with your local food safety authority or larger food safety agencies on the potential food safety hazards and their allowable limits.
In addition to scientific studies, news on cases of foodborne illnesses offers valuable information. These reports of food poisoning include information on any causative agent as well as the lapses in food handling practices that could have led to the outbreak. News can include minor cases of foodborne illnesses, major outbreaks, food recalls, significant violations, and new food safety regulations. Food safety agencies usually compile major food poisoning outbreaks as records that you can access to fully equip your team with proper hazard analysis.
In part of making effective food safety systems, it's important to communicate the plans and procedures with your entire team. During this process, you can gather information from them as well. Those who have already been in the food industry for a very long time can offer valuable information from their experiences. Additionally, you can seek the expertise of food safety consultants in identifying food safety hazards in your process. Their experience can assure you that hazards will be properly identified and analyzed.
Food safety hazards, although they will always be present, can surely be controlled or eliminated. There are many food safety and hygiene practices that have been devised to address different food safety hazards and are proven effective. The first step in knowing how to prevent these hazards is having substantial knowledge about them.
Below are some ways that you could implement in your food business to help address food safety hazards:
With sufficient knowledge about the present food safety hazards in your operations, you can formulate plans on how to address them. Proper identification means listing the potential sources of these hazards as well as factors that can promote their presence. From this information, you can come up with food safety practices that will target their weaknesses or root cause. Addressing these food safety hazards before they even cause widespread foodborne illnesses is more economical and effective in protecting consumer health.
As a food business owner, it's normal to have more than one supplier for the same product. You do not have direct control over their food safety practices but you can set standards that they will have to follow. Because you cannot regularly inspect their management system, you can request certificates and test results as proof of the safety of their supplies. This step requires any supplier to uphold very high standards of food safety practices to satisfy different businesses. In addition, receiving high-quality materials removes the extra burden of having to implement very strict inspection standards and preconditioning on your part.
Obviously, food safety hazards can be controlled with basic food safety practices. This step means following basic food safety rules including:
These basic steps are the foundation of most food safety practices. They aim to prevent the spread of pathogenic hazards and control their growth. Steps such as cleaning include personal hygiene practices, proper handwashing, and religious sanitation of different food contact surfaces. Cooking, on the other hand, eliminates biological food safety hazards by subjecting the food to high temperatures that are unfavorable for pathogens. Lastly, to prevent the further spread of pathogens and to control their growth, both raw foods and cooked products are chilled in refrigerated conditions.
Waste materials attract pests, and these pests invite a multitude of food safety hazards. Controlling these factors requires a strict management system on how to properly store and dispose of waste materials. Once this has been managed, the first step to eradicating pests, which is removing their source of food, is covered, Adding to this, potential shelters for pests such as dark spots or rarely used storage areas must be kept clean and regularly checked.
A holistic approach to addressing concerns regarding food safety hazards is having a comprehensive food safety management system (FSMS). This program contains sets of food handling practices that are particular for the food safety hazards in your operations. Additionally, food safety rules and regulations are considered in making an FSMS as a reference for monitoring. To ensure that these practices are followed and that laws and regulations are always in check, monitoring procedures and verification methods must be included in an FSMS.
In addition to these suggestions, higher food safety systems are available in the food industry. These systems include HACCP, ISO, and FSSC which implement very strict hygiene and safety standards for the protection of public health. In addressing food safety hazards, remember that preventing their spread or mere existence is more economically sound and safe for consumers. This lessens the problems with having to control an outbreak and its negative effects on your food business.
Each year, at least 600 million people become afflicted with foodborne illnesses because of contaminated foods in a year. This translates to 1 in 10 people in the world which significantly affects all other industries each year. Foodborne illnesses reduce productivity in any community as the labor force becomes unable to perform well. The first step to preventing the occurrence of these foodborne illnesses is the proper identification of food safety hazards.
More than just simple foodborne diseases, food safety hazards can cause death or serious injuries in severe cases. This does not only pose a great threat to public health but your food business as well. Consumers value the sense of safety that a food business provides them. If news linking your food business to any food safety issue becomes reported, you can risk losing your market and profit significantly.
In terms of internal advantages, properly identifying food safety hazards and communicating them with your team encourages a more productive work system. When food handlers are aware of what they should monitor and which practices should be avoided, work becomes faster and more efficient. This also allows your team to identify which practices would be most effective to eliminate specific food safety hazards. It also gives them an idea of which foo safety laws need to be followed.
With proper identification, analysis, processing, and monitoring, food safety hazards can be significantly controlled. To do this, food business owners must be able to implement a working and comprehensive FSMS in their food business system. These processes must be manually manned by an employee to ensure that they are being carried out properly. On top of that and as the owner, it is your task to oversee every single task being applied every day. This is on top of managing your daily business operations.
