Biological Hazards in Food: How to Implement Safety Practices

By Ajoy Gonsalves

In the domain of food safety, there's one question that keeps resurfacing - how can we prevent biological hazards? As the leading cause of foodborne diseases, it's crucial that we address this issue. This blog post delves into the steps you can take to prevent the transmission of harmful organisms and ensure the health of your customers.

Understanding Biological Hazards

Biological hazards refer to living organisms or substances produced by these organisms that pose a threat to human health. They're primarily responsible for foodborne illnesses, and they mostly take the form of bacteria, viruses, parasites, or fungi.


Bacteria are single-celled microorganisms that exist both in the environment and within humans and animals. They reproduce rapidly and are often found in foods left out at room temperature for too long or cooked incorrectly. Illness-causing bacteria like E. coli and salmonella can enter the body through contaminated food or water, leading to symptoms like fever, abdominal cramps, and diarrhea.


Unlike other living organisms, viruses lack a cellular structure. They must infect other cells to reproduce. Common foodborne viruses include hepatitis A, hepatitis B, and rotavirus, which can be found in food products such as milk or water.


Parasites like tapeworms survive by living inside another organism (host). They often infect animals before contaminating humans through undercooked meat or fish products.

Preventing Biological Hazards: Effective Food Safety Practices

Preventing biological hazards in food safety involves a blend of diverse practices. Let's dive into some key techniques that can help mitigate the risk of biological hazards in food.

Proper Hand Hygiene

The most basic yet crucial measure to prevent cross-contamination is ensuring proper and frequent hand hygiene for all individuals involved in food handling.

Temperature Control

Maintaining the correct temperatures for food storage can significantly reduce the growth of harmful bacteria. Cold foods should be kept at 40°F (4°C) or below, and hot foods should be kept at 140°F (60°C) or above.

Proper Cooking and Reheating

Thorough cooking and reheating can kill harmful bacteria present in the food. Each type of food has a specific recommended internal temperature to ensure its safety.

Avoiding Cross-Contamination

Using separate cutting boards and utensils for different types of food can help prevent cross-contamination between raw and cooked or ready-to-eat foods.

Regular Cleaning and Sanitization

Regular cleaning and sanitizing of all food contact surfaces, utensils, and equipment used in food preparation can significantly reduce the risk of bacterial contamination.

Q: What are the "Big 5" foodborne illnesses? A: Shigellosis, E. coli poisoning, Salmonellosis, Norovirus, and Hepatitis A

Q: What is the Temperature Danger Zone? A: 41-135 degrees Fahrenheit. This is where biological hazards are likely to multiply rapidly.

Q: How long should you scrub hands when handwashing? A: 15 seconds—about how long it takes to sing the ABC song

Q: What are germs and how could they be passed to the customer? A: "Germs" is a common way to refer to pathogens. They often come in contact with food through people, contaminated food, and food contact surfaces that haven’t been cleaned and sanitized.


Understanding and implementing food safety practices are crucial in preventing biological hazards. By adhering to these practices, we can safeguard public health and ensure the success of any food-related enterprise.
