An epigraph, a project outline, and Cyberleninka as a source of information

For any good project, you naturally need a good epigraph.
I was writing about safety, so I borrowed one from the IT crowd—in the modern world, they’re the first ones who come to mind when you think of security.
Here’s the epigraph I chose:

Security is a process, not a result.
Security demands constant oversight and improvement.
New threats emerge daily, and a previously high level of security can become powerless against them.
Only companies that consciously implement a continuous security process can achieve sustainable results.

Now it was time to write the most crucial part of the project: the Table of Contents.
It’s tough to keep 30-50 pages of a project straight in your head, so a clear and logical Table of Contents acts as your North Star.
The moment you feel like you’re veering off course, a quick look at it will get you back on track.

Here’s how the Table of Contents turned out:

  1. Introduction
  2. State Regulation and Control
  3. Statistics on Mortality from Food Poisoning
  4. The Safety of Agricultural Products & Environmental Causes of Contamination
    4.1. Soil
    4.2. Fertilizers
    4.3. Water and Other Conditions
    4.4. Transportation and Gas Environments
    4.5. Antibiotics and Animal Feed
  5. Safety in Food Production Facilities
    5.1. Harvesting and Processing Conditions
  6. The Safety of Food Products
  7. Methods for Maintaining Microbiological Safety in the Food Industry
    7.1. Traditional Methods: Sanitation, Hygiene, Pest Control
    7.2. Modern Methods: Irradiation, Disinfection, Inoculation with Beneficial Bacteria
  8. Conclusions

Not perfect, but not bad at all, I think.
Now, it was time to fill the project with actual content.

An important note on sources

The assignment for this project, as well as for my previous project on Foam Suppression, recommended using patent databases.
Russian patents can be found at this address, and if you know English, US patents are available here.
The world-class database from the World Intellectual Property Organization (WIPO) is here, and the European one is here.

But you need to grasp the sheer volume of this information. WIPO has 114 million documents, the European database has 140 million, the US database contains every patent since 1790, and Russia isn’t far behind.
Personally, I think using patent databases for a high school project is overkill. Patent attorneys—specially trained professionals with university degrees whose entire job is to help inventors navigate these systems—spend weeks on a single search!
So, if you’re writing a project for school and not for a national-level Olympiad, forget about patents. Stick to Cyberleninka and textbooks, just as I advised in my first article!
If your project is fairly large, I recommend saving not only the titles and links to the articles you need but also a brief summary of each. This will dramatically speed up the writing process later on.
Furthermore, I highly recommend using Wikipedia. Some people think it’s full of unverified information. But firstly, we’re not writing a doctoral dissertation.
And secondly, in Russia, PhDs and other high-level academics get their degrees revoked every year, so you should probably take the words of any «Academician» with a grain of salt.
I practice what I preach, so from here on out, it’s all Cyberleninka.

Project sources & summaries

2. State regulation and control

  1. How Poisoning Incidents in Schools Affect Rospotrebnadzor’s Inspection Targeting
    • Summary: Authors analyze media reports on mass poisonings in Russian schools and official inspection data. They find that schools are among the most heavily inspected organizations, bearing a significant regulatory burden. The study concludes that the risk-based approach to inspections is limited and that major incidents do not lead to observable changes in inspection strategies.
  2. Microbiological Food Safety: The Development of a Regulatory and Methodological Framework
  3. Current Issues in the Microbiological Safety of Food Products
    • Summary: The WHO estimates that over 30 harmful agents in food cause 600 million illnesses and 420,000 deaths annually (2010 data), with 40% of the burden falling on children under 5. The rise in foodborne illnesses is linked to negligence, improper food handling, the global spread of pathogens, industrialization of food production, complex supply chains, and lifestyle changes like eating out more often.
  4. Risk Assessment of Microbiological Safety in Poultry Products and Equipment in Slaughterhouses
    • Summary: Foodborne toxicoinfections are a major socioeconomic problem. The epidemiology is changing rapidly, with new antibiotic-resistant and cold-tolerant pathogens (like Campylobacter jejuni, Yersinia enterocolitica, Listeria monocytogenes) emerging. These agents are more aggressive and can cause severe chronic complications and higher mortality.
  5. Microbiological Safety and Quality Control of Poultry Products in St. Petersburg and Leningrad Oblast Retail Chains
    • Summary: Food products can contain up to 70% of the foreign substances entering the human body. This study of poultry from major producers («Roskar,» «Sinyavinskaya,» etc.) found six types of bacterial contamination, with colibacillosis being the most common (27%), followed by streptococcosis (18%) and staphylococcosis (8%).

3. Statistics on mortality from food poisoning

  1. The Reliability of Mortality Statistics (A Case Study of Deaths from Injuries and Poisoning in Moscow)
    • Summary: An analysis of 6,513 male and 1,560 female death certificates from 2003 in Moscow for working-age individuals who died from trauma and poisoning.
  2. Mortality Rates from Acute Poisoning in the Republic of Bashkortostan
    • Summary: A study of poisoning deaths from 1981-2010. Rates were stable in the 1980s but surged after 1991, peaking in 2002 at 48.8 deaths per 100,000 people before gradually declining to 24.1 by 2010.
  3. Premature Mortality from Acute Poisoning in the Sverdlovsk Oblast and its Socio-Economic Consequences
    • Summary: Calculates the economic damage from premature deaths due to poisoning by correlating years of life lost with the region’s gross regional product per capita.
  4. Analysis of Mortality from Accidents, Injuries, and Poisoning in the Republic of Kazakhstan
    • Summary: A retrospective analysis from 2010-2020 shows a significant decrease in mortality from these causes. The rate peaked in 2004-2006 at around 150 per 100,000 people and fell to 65.35 by 2019.

4. The safety of agricultural products & environmental causes of contamination

4.1. Soil
10. Methodology and Indicators for Sanitary-Microbiological Soil Safety Control (Analytical Review)
* Summary: Soil is a primary reservoir for pathogenic microorganisms. This review discusses control methods for biological contamination, official assessment standards, and the microorganisms that indicate clean versus contaminated soil.
4.2. Fertilizers
11. Roundup by Monsanto (Bayer) Causes Cancer.
4.3. Water and Other Conditions
12. A Case of Food Poisoning from Bee Honey
* Summary: An investigation found that bees were collecting nectar from henbane and datura flowers growing near the apiary, leading to toxic honey.
13. Heavy Metal Content in the Organs and Tissues of the Mountain Hare
* Summary: A study of hares from clean and industrially polluted areas in the Krasnoyarsk Krai. Hares from polluted territories showed significantly higher levels of lead and cadmium. About 40% of liver samples and all muscle tissue samples from these hares were unfit for human consumption, posing a toxic risk to local hunters and their families.
4.4. Transportation and Gas Environments
14. A Study of Temperature Regimes for Transporting Fruit and Vegetable Products
15. What a Fruit
* Summary: A shop owner explains that bananas are a «locomotive» product—essential for assortment but not very profitable. They spoil quickly: «I bring two boxes to the store, sell one and a half, and throw out half a box.»
16. Microbiological Purity of Fruits During Freezing and Low-Temperature Storage
* Summary: Freezing slows but does not eliminate microbial growth or toxins. Research is needed to understand how different freezing methods affect the microbial load on fruits like apricots and cherry plums intended for long-term storage.
4.5. Antibiotics and Animal Feed
17. Microbiological Analysis of Quail Meat When Using an Organic Concentrate Based on Poultry Bio-waste
* Summary: This study explored using microwave-disinfected poultry bio-waste as a component in quail feed. The resulting quail meat was found to be microbiologically safe.
18. Microbiological Safety of Egg Products with the Use of the Probiotic «Nord-Bakt»
* Summary: Adding the probiotic «Nord-Bakt» to the diet of laying hens was shown to improve the microbiological safety of eggs, reducing contamination from pathogenic bacteria and fungi while increasing beneficial bifidobacteria. It also improved the nutritional content of the eggs.

5. Safety in food production facilities

5.1. Harvesting and Processing Conditions
Mechanical processing (slicing, grinding) of products like meat increases microbial contamination.
Chemical treatments (preservatives, spices, acids, smoking) and modified atmosphere packaging are used to suppress microbial growth.
Reducing moisture through drying is a traditional method.
High osmotic pressure (using salt or sugar) also creates an unfavorable environment for microbes.
Thermal processing is most effective for killing microorganisms, but it often destroys vitamins.
Many pathogens are resistant to low temperatures; for example, Salmonella typhi can survive in frozen strawberries (-18°C) for up to 6 months.

6. The safety of food products

  1. Microbiological Contamination of Food Raw Materials and Finished Products (Analytical Review)
    • Summary: This review covers sources of contamination and prevention methods. For ready-to-eat composite products, heat treatment is crucial.
      Modern technologies like flash freezing, electromagnetic field treatment, and protective food coatings can also minimize risk.
  2. On the Microbiological Purity and Safety of Alcohol Production Products
  3. Meat in Human Nutrition: An Overview of Current Issues and Scientific Answers

  6. The Air in Production Facilities: Its Composition and Properties

Phew. That’s not even all the sources, but formatting them for the website is such a colossal pain (you have to insert each link and manually set it to be ignored by search engines) that I decided to skip publishing the remaining 30 or so.

So, what conclusions can I draw, and what recommendations can I offer after reviewing all this?

  1. If you have the option to never leave your apartment, don’t.
  2. If you must go out, bring two or three packs of anti-poisoning tablets, a sealed bottle of water, insect repellent, and a nitrate tester.
    And a good organic chemistry textbook, of course. It might just save your life one day.
  3. Stuff everything you need into the pockets of your hazmat suit. A diving suit will also work.
  4. Never, ever, ever buy anything from a farmers’ market.
  5. Try not to eat meat, fish, or vegetables (unless you grew them yourself on pre-sanitized soil).
    I also don’t recommend fruits (especially bananas!) or dried fruits. Ice cream is off the table, in any form.
    You already know bread is bad for you.
  6. I recommend carrying a Geiger counter (see source #42). Your food might have been disinfected with gamma rays.
  7. Befriend an ER doctor and, if possible, only go for walks with them.
  8. Watch out for yourself, and be careful!
