The Science of Handwashing: Removing Transient Bacteria vs. Managing Resident Flora
Daily handwashing effectively removes dirt and transient bacteria picked up from the environment. However, it cannot eliminate the resident bacteria that naturally live on our hands. For example, Staphylococcus aureus (staph), a common bacterium, often remains untouched and may even be brought to the surface during washing. This increases the risk of contaminating food. This article explores the microbiological principles behind handwashing, highlighting its limitations and the implications for food safety.
Histamine forming bacteria
In this article, we will explore the types of food that commonly lead to histamine food poisoning, the causes, symptoms of histamine food poisoning, prevention methods, the bacteria that produce histamine, why the histidine decarboxylation reaction occurs in bacteria, the fact that heating food does not eliminate histamine once it's formed, and the misconception that fish is the only cause of this issue.
Understanding Cronobacter sakazakii: Risks, Prevention, and Safe Formula Preparation for Infants
In this article, let's unravel the mystery of Cronobacter sakazakii, a bacterium that's causing concern due to its sneaky way of contaminating infant formula. We'll tackle why this particular germ is worrisome for babies and also discuss the dos and don'ts when preparing baby formula, all from the viewpoint of keeping those tiny tots safe.
Norovirus: Characteristics, Transmission Routes, and Effective Prevention

Clostridium perfringens: How to Prevent Food Poisoning from the 'Cafeteria Germ' in Bulk Meal Preparation
Clostridium perfringens, commonly referred to as the "cafeteria germ," is a key cause of large-scale food poisoning outbreaks, particularly in high-volume meal preparation settings. This bacterium thrives in warm, oxygen-free environments, often found in slow-cooling dishes like stews and curries. In this article, we explore the unique traits of C. perfringens, its role in foodborne illness, and critical steps for preventing contamination to ensure food safety in catering facilities, cafeterias, and restaurants.
Listeria monocytogenes: Risks, Regulations, and Effective Control in Ready-to-Eat Foods
This article explores Listeria monocytogenes, a resilient Gram-positive bacterium responsible for severe foodborne illness, particularly affecting pregnant women, the elderly, and those with weakened immune systems. Learn why this pathogen is a critical concern in ready-to-eat foods such as deli meats, cheeses, and smoked seafood. We delve into its unique survival abilities, its high fatality rate in outbreaks, and the regulatory differences across the U.S., EU, and Japan. Discover best practices and strategies to control this persistent threat in food production and safeguard public health.
Staphylococcus aureus: From Skin Infections to Heat-Resistant Food Toxins – Your Essential Guide
