Which Food Safety Practice Will Help Prevent Biological Hazards

Which Food Safety Practice Will Help Prevent Biological Hazards? Zarina Mohd, process project manager at Integrated Food Projects, discusses biological hazards in food production and emphasizes the importance of the manufacturing process’s processing stage.

Biological hazards are organisms or substances produced by organisms that are harmful to human health. These organisms or substances can include bacteria, viruses, yeasts, and molds. These organisms can have an impact on our health, with consumption frequently resulting in infection, intoxication, or even death. Prevention throughout the food production process is the most effective way to control biological hazards.

Major biological hazards

Bacteria, for example:

Enterohaemorrhagic Salmonella spp. The bacteria Escherichia coli, Campylobacter jejuni, Campylobacter spp. Enterocolitica Yersinia, Monocytogenes Listeria, Bacillus anthracis, Bacillus cereus, Staphylococcus aureus, Clostridium botulinum, Clostridium perfringens, Vibrio vulnificus, and Vibrio parahaemolyticus are the bacteria that cause anthrax.

Virus illustration:

Hepatitis A and Norwalk viruses, as well as Rotavirus

Sites like:

Cryptosporidia, Giardia spp., Trichinella spiralis, Taenia solium, and Anisakis spp.

What are the four types of food safety risks?

Food safety risks are classified into four categories. Each category describes the nature of the food safety hazard and informs food handlers about the best practices for controlling it. Food safety risks include any of the following:

  • Biological
  • Chemical
  • Physical
  • Allergenic

All of the agents that can cause foodborne illnesses or allergic reactions in consumers are included in this list of food safety hazards. These food safety hazards can have a mild or significant impact on public health, depending on factors such as contamination level, the likelihood of occurrence, and potential damage.

Biological hazards in food

Biological hazards are the most common cause of foodborne disease among the three food hazards—biological, chemical, and physical. You may be aware that pathogens, or harmful microorganisms such as viruses, bacteria, and parasites, are involved in these hazards. Some of the most infamous foodborne illness outbreaks are caused by pathogens such as Salmonella and E. coli, making biological hazards an important consideration for establishments seeking to maintain a reputation for safety and dependability.

Preventing Biological Hazards

Implementing robust processing and storage strategies is the best way to keep biological hazards from affecting customers. Kill steps used prior to packaging are required, such as thorough cooking or pasteurization of milk and juices. The use of packaging technologies such as vacuum sealing during processing inhibits bacterial growth. Proper temperature control during storage can significantly reduce microbe growth. Finally, effective sanitation practices throughout the distribution chain will reduce food product cross-contamination.

Quiz on Food Safety and Environmental Hazards

Food safety refers to food preparation, handling, and storage procedures designed to prevent foodborne illness and injury. Food products may encounter a variety of health hazards as they travel through the supply chain, from farm to factory to fork. To reduce these risks and protect consumers, safe food handling practices and procedures are implemented at every stage of the food production life cycle.

Food safety, as a scientific discipline, draws on a wide range of academic disciplines, including chemistry, microbiology, and engineering. These various schools of thought come together to ensure food processing safety wherever food products are sourced, manufactured, prepared, stored, or sold. Food safety, in this sense, is a systemic approach to hygiene and accountability that affects every aspect of the global food industry.

Chemical Dangers

The presence of harmful substances that can be found naturally in food or unintentionally added during processing identifies chemical hazards. Naturally occurring chemicals such as mycotoxins, intentionally added chemicals such as the preservative sodium nitrate, and unintentionally added chemicals such as pesticides are examples of chemical hazards.

Food Manufacturing Regulations

Almost every product on UK supermarket shelves is supplied by large-scale food manufacturing industries. The production of finished packaged foods can include a variety of stages such as slicing and cutting, mixing, marinating, grinding, and so on. The hygienic design of equipment is important in controlling microbiological safety, as it is designed to be easily cleaned because microorganisms cannot multiply on clean dry surfaces!

When it comes to biological hazards, there is so much to learn. I just hope this blog gave us all a good understanding of the importance and effectiveness of preventative measures in reducing harmful organisms that have a negative impact on the food production process.


Prions are small pathogenic proteins that, like viruses, require the presence of a living host in order to grow and survive. They were only recently discovered and are best known for causing mad cow disease (bovine spongiform encephalopathy), a fatal brain infection in cattle and other livestock. Animal protein is prohibited in veterinary feed for cows, sheep, and goats under FDA regulations that went into effect in 1997. 21 Because prions cannot be detected by color, odor, or taste, the best way to avoid this pathogen is to avoid contaminated meats and to heed food warnings.


The primary biological contaminants in food are:

  • animal guts: fecal contamination
  • soil and water contaminated by non-treated manure
  • Cross-infection:- Human contamination as a result of poor personal hygiene Hygiene, fecal contamination, and infection failure control (illness not reported)
  • Food product cross-contamination caused by the processing environment as a result of poor/improper sanitation

What are the seven kitchen dangers?

The following are seven of the most common kitchen hazards:

  • Cross-contamination
  • Physical injuries caused by utensils and equipment
  • Chemical contamination of food by accident
  • Fire dangers
  • Food contamination caused by physical objects such as jewelry or hair
  • Food spoilage as a result of improper storage temperature
  • Food preparation errors

Physical Dangers

Foreign objects found in food products are considered physical hazards. They are either naturally occurring in the specific item, such as fruit stems, or are not normally found in the food item, such as hair or plastic. Unnatural physical hazards are generally more hazardous to one’s health, whereas natural physical hazards can be completely harmless.

Physical Hazards Avoidance

Physical hazard prevention focuses primarily on thorough food inspection and strict adherence to food safety regulations, such as the Hazard Analysis Critical Control Point (HACCP) discussed below. Organizations can also take preventative measures to eliminate the possibility of a physical hazard. Light bulbs, for example, can be made from a variety of materials. Acrylic is lighter and stronger than glass, and it shatters into larger, blunter fragments.

Allergenic Dangers

The final, and possibly most lethal, the category is allergenic hazards. Allergies are the sixth leading cause of chronic illness in the United States, affecting more than 50 million people each year. Allergic reactions occur when the human body responds abnormally to specific proteins found in food.

Preventing Allergenic Risks

Unfortunately, there is no way to prevent allergies, but the risk of an allergic reaction can be reduced. Allergic reactions can be reduced if companies use proper sanitation techniques and clearly label potential allergenic ingredients on product packaging. Preventing an allergic reaction is primarily the responsibility of the consumer, but they can only do so effectively if businesses do their part with proper sanitation and ingredient labeling.

How do you manage major food safety risks?

  1. Control measures in your food service establishment
  2. Obtain a copy of your risk assessment and HACCP plan.
  3. Check to see if the hazard/control measure combination is aligned.
  4. Correct any errors and update your documents.

Incorporate any modified control measures into your food business.

What are the five most dangerous foods?

  • Meats, either raw or cooked
  • Fruits and vegetables, freshly cut
  • Seafood
  • Milk and dairy products
  • Pasta and rice

Regulations and legislation

Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) regulations have helped to reduce food safety risks and ensure safer food safety practices. As a result, food safety practices have become far more robust and effective.

What exactly are food hazards?

A food safety hazard is anything in food that has the potential to cause illness or injury to the consumer. Biological, chemical, or physical objects can pose a threat to food safety.

How do you spot food poisoning?

The proper identification of food hazards is a component of the most prominent food safety management systems, such as the Hazard Analysis Critical Control Points (HACCP) system. Identification and analysis are preventative measures for dealing with the potential consequences of these safety hazards. Because public health is dependent on them, the foundation for hazard identification must be established and reliable resources.

Critical Control Point Hazard Analysis (HACCP)

HACCP, which was implemented in 1997, changed food safety methodology from sight, smell, and touch inspection to science-based inspection. The core principles of HACCP provide a framework for analyzing biological, chemical, and physical hazards throughout the supply chain. This prevents outbreaks rather than responding to them after the fact, and it has aided in the acceleration of technology used to manage food safety. As a result of HACCP, foodborne illnesses are drastically reduced.

How do you deal with potential hazards?

You should take the following steps to control workplace hazards and eliminate or reduce risk:

  • Perform a workplace risk assessment to identify the hazard.
  • determine how employees may be endangered;
  • assess the dangers;
  • Hazards should be recorded and reviewed at least once a year, or sooner if something changes.
