A Complete Guide For Understanding Food Safety Hazards

Food Safety Hazards

Table of Contents

Food safety hazards are any external agents in the food supply chains. These agents can cause loss of human life by contamination of the food materials.

Contamination by these hazards can occur at any step of the food supply chain. These include transportation, packaging, serving, delivery, and food storage. This can result in foodborne illnesses and create serious health risks to consumers.

To maintain food safety standards, we must understand these hazards as they enable proactive identification and prevention strategies throughout the food chain that ensure safe products reach consumers.

In this blog, we will look at the main types of food safety hazards and explore the measures that food businesses can implement to maintain food safety standards.

Major Types of Food Safety Hazards for Foodborne Illnesses

Several food safety hazards can provoke many foodborne diseases. However, these have been categorized into four distinct categories. The four significant food safety hazards are biological, chemical, physical, and allergenic.

The potential damage a food hazard can cause can mildly or significantly affect the health of those who consume it. The level of contamination affects the level of the outbreak.

Chemical Food Hazards for Foodborne Illnesses

The hazards that fall under this category are the chemical substances that are manually added to the foods, or they are innate-like the food. These can cause injury to humans or food-borne illnesses. An instance of naturally occurring harmful chemicals is the saponins from legumes.

These can become hazardous when the components are used excessively or without adequate consumer labeling. Furthermore, chemicals such as fertilizers, machine oil, antibiotics, heavy metal compounds, and pesticide residues are categorized as unintentional chemical hazards that may affect consumers when consumed.

Examples of the Most Common Sources of Chemical Food Hazards

These hazards may be naturally present in materials, unintentionally introduced in the foods, or added intentionally. A chemical food hazard also occurs due to processing abuse during heating treatments. The food industry has mentioned below some of the familiar chemical food hazards examples in the food business:

  • Amendments in the Soil

When the raw materials, such as fruits and vegetables, are in the growth stage, the quality of the soil and any amendments added to the soil can affect the final product. The plants could also absorb any unwanted chemicals from their growing soil.

One typical example is how green tea plants can absorb heavy metals from the soil, such as lead, around their growing areas. It also includes chemicals from herbicides, pesticides, and fertilizers that are applied during the growth period.

  • The Heat Treatment

The chemical food hazards can sometimes indicate an incorrect process being followed or skewed conditions from the original method. In the case of a chemical acrylamide, the food inspectors can determine that food has been treated with excessive heat when they detect high levels of acrylamide in the food.

This chemical compound is formed due to high temperatures, which provide suitable conditions for the sugars and proteins in food to react with each other. Prolonged human exposure to this chemical is proven to increase the risk for various types of cancers in humans.

  • Cleaning Agents

Adding cleaning and sanitation solutions is considered an unintentional chemical food safety hazard. These solutions can work themselves into the food due to inadequate washing with water. Some sanitizing agents, such as chlorine, even in small amounts, can be harmful and affect the quality and safety of the food.

  • Raw Materials for the Food

Some raw materials for food, such as fish, can also contain harmful toxins. One case is that of the Fugu or pufferfish, a delicacy for Japanese restaurants. This fish has tetrodotoxin, which is a potent neurotoxin.

It is a natural defense mechanism for the fish. Only specialized and a handful of chefs can follow the techniques required to remove the risks of chemical food hazards for the consumption of the public.

  • Food Preservatives and Additives

Certain compounds, such as sodium nitrate, used to cure meat, and sodium sulfite, as an antifungal agent, also fall into the category of chemical food hazards. For some more vulnerable individuals, sodium nitrite can increase the risk of heart disease, and sodium nitrate can cause allergic reactions.

These chemical compounds can also become highly dangerous if they are added in unregulated amounts that surpass the specified standards by the food regulators.

Biological Hazards of Foodborne Illnesses

The biological hazards of foodborne diseases generally contain contaminants innate to the living organism, including pathogens such as yeasts, fungi, bacteria, and parasites.

These hazards can be detrimental to public health, as these can cause foodborne diseases ranging from very high to very low. The most common factor for outbreaks in the industry is biological hazards.

Examples of the Most Common Sources of Biological Hazards

Biological hazards are the most common form of hazards that breach food safety hazards. It is present in food production sites and food service areas. The presence is enhanced during harvesting raw materials, with the mentioned below being some of the most common sources of biological hazards.

  • Water Contamination

In some instances, water can become contaminated with hazards, especially when the source doesn’t have proper treatment and is unsecured. Water is one of the best mediums for transferring widely known pathogens such as Escherichia coli, Hepatitis E, Norovirus, Campylobacter, and parasites.

It is because water is used in the food industry operations, which can quickly superspread these biological hazards. Therefore, water treatment is highly critical.

  • Handling of Food by Humans

As the food handlers are humans most of the time, we humans also host several pathogens. According to research, 25% of animals and humans have harmful bacteria such as Staphylococcus aureus on their skins.

It can cause Staphylococcal food poisoning, and it is reported to have had almost 100,000 severe cases in the USA. Additionally, the natural pathogens on the skin of humans carry biological food hazards around.

  • Raw Food Materials

All of the food materials innately consist of naturally occurring biological hazards. These foods are one of the best sources of these hazards. The raw materials include vegetables, fruits, and root crops.

These are more likely to harbor soil-borne pathogens and require proper treatment, such as intensive washing, before using these for further food processing.

  • The Materials Used for Food Packaging

The packaging of the food comes into direct contact with the food. The packaging must be sterilized to ensure the contact is not harmful, as the packaging can harbor contaminants.

Materials such as cartons, cans, and plastics are not entirely free from biological hazards. Bottles, for instance, must be completely dry to prevent moisture, which can attract biological hazards.

  • Storage Areas of the Food

Be it raw materials or finished products, the storage area for the food can harbor several biological hazards, primarily those with minimal packaging. When the temperature control is inadequate, there is a lack of cleaning of the storage areas and poor maintenance practices, which can increase the biological hazards.

In the case of refrigerated storage, ready-to-eat foods and mixing raw materials can increase the chances of cross-contamination of food. Small leftover pieces of food or trapped juices can also start gathering biological contaminants by providing ideal conditions.

  • Machinery and Equipment Food Contact

If the food makes contact with the un-sanitized processing equipment, it is possible that the equipment harbors hazards that will cause the food to come in contact with contaminants and get spoiled.
Some hazards can also produce slime on the equipment’s surfaces, making them resist regular cleaning procedures.

  • Pests

Certain pests, such as lizards, birds, insects, and rodents, can transfer pathogenic organisms inside a restaurant in several ways.

Their droppings are minor and go away unnoticed most of the time. So they can easily get included in food and set a situation we do not wish to comprehend.

Physical Hazards for Foodborne Illnesses

Food safety physical hazards are defined as any extra material or foreign objects being included inside and contaminating the food. These can result in acts of severe injury or serve as growth areas for dangerous pathogens.

These hazards can be prevented by making inspections and physical observations. Automatic detectors may be used for a large volume of productions.

Examples of the Most Common Sources of Physical Hazards

There are several sources of physical hazards inside the line of production. These can come from machines, pests, or the food handlers themselves. Their detection is crucial as these can attract the spread of other hazards. Some of the most common sources of physical hazards are:

  • The Production Utensils and other Equipment

As factory equipment is involved in food production, parts of plastic and metal chips can easily get mixed into the food. It is standard for old equipment. Physical hazards such as screws, nails, and broken glass can originate from machines in production or kitchen areas and get mixed with the food.

  • Food Handlers

If a proper hygiene system is absent, the food handlers can contribute to physical hazards. They must have protective uniforms such as caps and hairnets that prevent strands of their hair from falling into the food being prepared. Furthermore, any pen caps and loose jewelry can cause physical hazards that can cause choking, etc.

  • Raw Materials

Some natural hazards occur naturally from the raw materials that are being used themselves. Bones in the meat are an example of a widespread contaminant alongside leaves and twigs on the fruits.

Additionally, some common commodities such as flour, salt, and sugar can be contaminated with hazards such as small rocks due to unclean supplier production areas. The detection of these hazards can prevent any injuries to consumers.

  • Allergens

The allergens are also food safety hazards. These are caused by specific proteins that an individual’s immune system may mistake as foreign matter that can be deemed dangerous.

Examples: Some common food allergens are tree nuts, shellfish, eggs, milk, fish, wheat, peanuts, soybean, lupin, celery, sesame, sulfites, sulfur dioxide, mollusk, and mustard. This is why it is the responsibility of the food business to inform consumers of any potential risks in food products.

Importance of Identifying Food Safety Hazards for the Food Business

According to a study, almost 600 million people are affected with food-related diseases yearly because of contaminated foods. It translates to nearly 1 in 10 people in the whole world.

These foodborne diseases reduce productivity in all communities as even the labor force cannot perform their duties as per routine. So, the first step to preventing foodborne diseases will be correctly identifying food safety hazards.

Consumers value the sense of safety that the food businesses provide them with. If the news links to your food and highlights any food safety issues, the company can significantly lose the profit and the market.

Food safety hazards also have internal advantages. When a food business can identify food safety hazards and effectively communicate them with the employees, this creates a very productive environment for the flow.

This also allows the workforce to identify best practices to eliminate specific food safety hazards. This also ensures that all the food safety laws are followed as well.

How to Identify Hazards?

Identifying hazards within a food service operation is critical in providing customers and staff’s safety and well-being. Following are some of the most effective strategies for hazard identification:

Conduct a Comprehensive Hazard Analysis

Hazard analysis thoroughly examines potential hazards in a food chain from procurement to service. It requires understanding where and how contaminants could be introduced, whether at the receiving stage, during storage, or preparation and cooking.

Monitor Regularly

This strategy involves carefully observing sourcing practices to ensure that supplies come from reputable providers who meet safety standards.

Storage temperatures must be continuously checked to prevent bacterial growth, and cooking procedures should follow time-temperature guidelines to avoid pathogens.

Do Visual Inspections

Staff should be trained to detect signs of food spoilage, such as unusual odors, colors, or textures, and to spot foreign objects or signs of pest activity. These inspections should be frequent and systematic, ideally built into everyday operations.

Use Food Safety Management Systems

A food safety management system like the HACCP plan makes the hazard identification process more systematic. HACCP, in particular, assists in pinpointing critical control points throughout the food handling process. By targeting these areas, such as cooking or cooling, where the hazard risk is highest, operators can focus their monitoring and control efforts more effectively.

How to Prevent Hazards

Whether you run a food manufacturing facility, a restaurant kitchen, or any other food handling area, taking the best measures to prevent food hazards might be your top priority. Good manufacturing practices are guidelines to ensure that food products are produced and controlled according to quality standards.

By incorporating the given practices, you can prevent contamination, mix-ups, and errors in the food handling process:

  • Regular maintenance of equipment and infrastructure to avoid cross-contamination
  • Regular cleaning and sanitization schedules for all equipment involved in food processing.
  • SOPs for receiving, inspecting, and storing raw materials to prevent contamination.
  • Implement measures to prevent pest infestations, such as regular inspections, sealing entry points, and proper waste management.
  • Regularly monitor temperatures in storage areas, refrigerators, and freezers to ensure food products are stored within safe temperatures.
  • Establish cleaning protocols for all food contact surfaces, equipment, and utensils.
