Relevance, introduction, and personal takeaways from the Microbiological safety project


As I wrote in the previous article, I decided not to publish links to additional sources that answer the following questions:

  1. Modern Chemical Hygiene Products for:
    • a) Floor cleaning
    • b) Dish processing
    • c) Personal hygiene products
    • d) Mild antibacterial agents (chlorhexidine and its analogs)
  2. Sanitary Regulations:
    • a) Personnel (hand washing, medical certificates, etc.)
    • b) Equipment — modern chemical, ultrasonic, light-based, and other disinfection methods.
    • c) Traditional disinfection methods (for example, covering a meat-chopping block with coarse salt overnight)
  3. Control of Rodents and Insects (insecticides)
  4. Rules for Storing and Serving Dishes (shelf life, temperature conditions)

You can find articles on these topics yourself on CyberLeninka in any quantity you need.
Now that the sources are available and it’s generally clear what and how to write, it’s time to write about the project’s Relevance and other mandatory sections, and, of course, the Introduction. It’s understood that one writes on these topics based on the material selected for their project.
So far, I’m honestly not yet a master of eloquent writing; it’s something I still need to work seriously on.
This is what I’ve come up with:

Project outline

Relevance: Food poisoning has an extremely negative impact on the population as a whole. Diseases related to it can transition from acute to chronic, leading to disability and even death. For adolescents, food poisoning poses additional risks—for example, a student who has been sick for half a year and hasn’t mastered the curriculum will be forced to repeat the grade. This creates an additional burden on the education system and leads to significant budget expenditures. Most importantly, it can affect how and when a young person finds their purpose in life. In other words, food poisoning can literally change a person’s entire life for the worse!
Aim of the Work: To examine and analyze the influence of poor-quality cleaning of raw food materials on the number of food poisoning incidents.
Objectives:
To analyze scientific and technical literature.
To draw conclusions based on the readings.
To compile a set of recommendations on cleaning raw food materials.
Research Method: Analysis.
Hypothesis: People experience a large number of food poisonings due to improper cleaning of raw materials and the preparation of semi-finished and finished foods in inadequate conditions.
Practical Significance: A reduction in the number of food poisoning incidents.
Personal Significance: This research will be useful as it will allow for a more detailed study of the causes of dangerous food poisonings of various natures and to understand what modern methods exist for combating them.

Introduction

The quality and safety of agricultural products, raw materials for food production, and food products themselves—on which the health and work capacity of the country’s population depend—are evaluated by chemical-technological, organoleptic, and microbiological indicators.
Microbiological indicators make it possible to assess product safety. They include the quantitative and qualitative composition of microorganisms in the product under study. Often, an externally very attractive product can cause serious poisoning or illness.
Microorganisms can enter the product throughout the entire technological chain of preparation, from raw materials to the finished product, including the stages of procurement, preparation, packaging, transportation, storage, and sale. They can enter products when regulatory sanitary-hygienic measures are not observed—from inventory, equipment, animals, insect pests, or via humans.
Each stage of food preparation requires specific forms of control, including control not only of the raw material or product itself but also of the environment in which this product is grown, stored, and processed.
To ensure the microbiological safety of food products at enterprises, factory laboratories conduct microbiological and sanitary-hygienic control at all stages of the technological process. This starts from raw materials and goes to finished products, in accordance with state standards, technical specifications, instructions, rules, methodological guides, and other regulatory documents developed for each branch of the food industry.
For individual food production facilities, there are their own microbiological control schemes that define the objects of control, sampling points, frequency of control, specify which microbiological indicator needs to be determined, and provide permissible norms.
Safety—especially and primarily microbiological safety—is the most important characteristic of food products. Safety is defined as the absence of harmful impurities of a chemical and biological nature, including pathogenic microorganisms and the toxic products of their activity.
The sanitary-hygienic regime and control are aimed at ensuring the favorable sanitary condition of the enterprise and the microbiological safety of the food products obtained. The purpose of sanitary-hygienic control is to identify the possible presence of pathogenic microorganisms. This control includes checking the biological purity of water, the air in production premises, food products, the sanitary condition of technological equipment, inventory, containers, and the hygienic condition of the staff (cleanliness of hands, clothing, etc.).
Indicators are determined according to the corresponding approved methodologies provided in regulatory documents: state standards, methodological guides, and instructions for microbiological and sanitary-hygienic control.
For the microbiological assessment of the quality and safety of individual groups of food products, indicators listed in the corresponding sections of SanPiN 2.3.2.1078–01 «Hygienic requirements for the safety and nutritional value of food products» are used. SanPiN also applies to the stages of creating and launching new types of products during their processing, obtaining, storage, transportation, procurement, and sale.
Practically all control objects undergo testing for the content of Mesophilic Aerobic and Facultatively Anaerobic Microorganisms (known in Russian as KMAFAnM)*.
For consumers, this indicator, often called the Total Viable Count (TVC), characterizes the quality, freshness, and safety of food products. The value of the TVC indicator depends on many factors, the most important being the temperature regime during transportation, storage, and sale of the product, humidity, etc. An increase in TVC indicates the multiplication of microorganisms, among which there may be microorganisms causing product spoilage (for example, molds). A large amount of TVC most often indicates violations of sanitary rules and the technological regime of production, as well as the terms and temperature regimes of storage, transportation, and sale of food products.
It should be particularly noted that a high content of TVC in food products can cause food poisoning. Young children, the elderly, and people with weakened immune systems are most susceptible to this disease. Products are also tested for the presence of coliform bacteria** (known in Russian as BGKP), pathogenic bacteria, including Salmonella, yeasts, and molds.
In some industries (for example, bakery, canning, sugar), additional microbiological indicators reflecting the specific features of a particular production are analyzed. Thus, in vegetable preserves, animal and plant fats, and in public catering products, the presence of sulfate-reducing clostridia is determined; in cereals—the presence of Bacillus cereus; in mineral and bottled waters—Pseudomonas aeruginosa; in egg products—bacteria of the genus Proteus, etc. Special methodologies described in the corresponding regulatory documentation are used for their accounting.

Based on everything written, my classmates and I created a project presentation, which we successfully presented in biology class to our homeroom teacher.
Currently, I no longer participate in this project.

Personal takeaways

I find working on this project useful for myself. I learned to search for necessary literature in CyberLeninka, learned about World Patent Databases, read a lot about food safety, and understood that buying anything from farmers’ markets is analogous to playing Russian roulette with a fully loaded revolver.
In addition, I figured out how to speed up work with an array of sources and learned to work with the software necessary for this acceleration. For my participation in the project and work with the sources, I received credit.

*KMAFAnM (total microbial count) is an extensive group of various microorganisms with which a food product can be contaminated.
**Coliform bacteria: Bacteria of the coliform group.
