The Importance of Hygiene and Sanitation in Food Safety


1. Introduction to food safety 

        Food safety refers to the measures taken to ensure that food products are free from contamination and safe for human consumption. It involves a series of practices, procedures, and controls that are designed to prevent foodborne illness, food spoilage, and other related problems. The goal of food safety is to prevent the spread of harmful microorganisms, such as bacteria, viruses, and parasites, in food products.

        Food safety practices can be applied at various stages of the food production process, including food handling, storage, preparation, and transportation. Good food safety practices involve a combination of hygiene and sanitation measures, proper food handling techniques, and effective controls to ensure that food products are not contaminated during production, processing, or distribution.

        Food safety is an important concern for consumers, food companies, and regulatory agencies, as contaminated food can lead to foodborne illness, economic losses, and other negative outcomes. By following best practices in food safety, companies can help to protect the health of consumers, maintain the quality and reputation of their products, and minimize the risk of food contamination.

  key terms

  • Food safety
    • Protecting food from anything that could harm
  • Contamination
    • The presence in food of any objectionable (unpleasant) or  harmful substance or material contaminants may be microbial, allergenic, physical, or chemical  
  • Hazard
    • Anything that could harm consumers, either by causing them an injury or making them unwell contaminants are food safety hazards
  • Risk 
    • The likelihood that a hazard will cause harm
  • Control measure 
    • An item, action, or procedure designed either to prevent or remove a hazard or to reduce the risk of it causing harm
    • A management system that identifies hazards, and control measure the safety of the food it stands for 'hazards analysis control point'
  • Foodborne illness 
    • Illness linked to eating contaminated food 

Benefits of good safety standards 
  1. We will have a good reputation and a secure and profitable in the  future 
  2. Our operational costs will be lower as less food is wasted 
  3. Our crew or team will have better working conditions and job security 
  4. Guest will be happy, and food will be safe to eat 


By law, everyone who works in the food industry has a duty to keep food safe, not just supervisors and managers.

To keep consumers safe from a food-borne illness you must:

  • Follow workplace rules for food hygiene (including keeping the workplace  and yourself clean, as well as following guidance for keeping food at  the right temperature) 
  • Protect food from contamination or anything that could cause harm  
  • Be alert to any food safety hazards and report them to your supervisor or manager 

2. Food safety  Hazzard 

You should develop knowledge and understanding of the concept of food contamination and be able to:

  • Identify the different types of a food safety hazard
    • Contamination is the presence in food of any objectionable or harmful substance or material. It occurs when hazards are not properly controlled. Types of contamination
      • Microbial  are bacteria and viruses  
      • Allergenic is typically naturally occurring proteins in foods that cause abnormal immune responses
      • Physical is a visible foreign object 
      • Chemical is an unwanted harmful substance that makes food unfit for consumption 
    • Contaminants are food safety hazards because they cause harm to the customers 
  • Explain why bacteria can cause problems in the food industry 
    • Bacteria can cause problems in the food industry because they can grow and multiply rapidly in food, leading to food spoilage and contamination. Some types of bacteria can also produce toxins that can cause food poisoning and other health problems in humans who consume contaminated food. Bacteria can also lead to the decreased shelf life of food products and loss of quality, affecting the reputation and profitability of the food industry. To prevent these problems, it is important for food companies to follow proper food handling, storage, and processing practices, as well as regularly test their products for bacterial contamination.
  • State the ideal condition for the multiplication of bacteria 
    • Bacteria need food such as meat products poultry, egg, milk, etc 
    • Time more than 4 hours
    • Temperature between 5 degrees to 57-degree celsius 
    • Moisture causes bacteria to need water to multiply 
    • Bacteria can't grow without Oxygen
    • Bacteria will grow in the acidity 
  • Explain what viruses are and how they differ from bacteria 
    • Viruses are tiny infectious agents that consist of genetic material (DNA or RNA) surrounded by a protein coat. They are much smaller than bacteria and cannot reproduce on their own. Instead, viruses invade host cells and take over the cell's machinery to produce more viruses. This often leads to the host cell being damaged or destroyed in the process.
    • Bacteria, on the other hand, are single-celled microorganisms that can exist and reproduce independently. They have a cell wall and can carry out all the functions necessary for life, including obtaining energy, producing waste, and reproducing. Bacteria can be found in a variety of environments, including soil, water, and the human body.
    • In summary, viruses are parasites that rely on host cells to reproduce, while bacteria are self-sufficient single-celled organisms.
  • Explain what is meant by cross-contamination and how to prevent it 
    • Cross-contamination occurs when bacteria or viruses are transferred from one place to another by someone or something, either directly or indirectly
      • Direct cross-contamination is when the source of the  bacteria or virus is in actual contact with the food, for example, raw meat touches ready-to-eat food when they are stored next to each other in the refrigerator
      • Indirect cross-contamination is when a vehicle transfers bacteria  or viruses from one surface to another, for example, if you use a knife to prepare meat on a chopping board and  then use the same knife  and  board to chop salad vegetables without  cleaning and disinfecting them, you could transfer bacteria from the raw meat to the salad and cause illness 

3. Good food safety practice  

Good food safety practices involve a series of steps and measures to ensure that food products are safe for consumption. Some of the key principles of good food safety practices include:

  • Personal hygiene: Food handlers should maintain high levels of personal hygiene, including regular hand washing, wearing clean clothing, and avoiding contaminated personal items in the food preparation area.

  • Food storage: Foods should be stored at appropriate temperatures to prevent the growth of bacteria and other microorganisms. This includes keeping perishable food refrigerated and frozen food frozen.

  • Food preparation: Food should be handled, prepared, and cooked to the appropriate temperature to kill harmful bacteria and other pathogens.

  • Pest control: Effective pest control measures should be in place to prevent contamination from pests such as rodents, insects, and birds.

  • Equipment and facility cleaning: Equipment and facilities should be cleaned and sanitized regularly to prevent the buildup of bacteria and other microorganisms.

  • Supplier management: Food companies should have systems in place to verify that their suppliers meet food safety standards.

  • HACCP (Hazard Analysis and Critical Control Points): HACCP is a food safety management system that identifies and controls potential hazards in the food production process.

By following these and other food safety practices, food companies can help to reduce the risk of food contamination and ensure that the food they produce is safe for consumption.
