Summary
A food crisis is a sharp rise in hunger and malnutrition, often triggered by supply or demand shocks and price spikes. Preventing food crises requires economic growth and stable food prices to ensure the poor have access to food.
Area of Science:
- Food security and nutrition science
- Global health and economics
Background:
- Food crises are defined by sharp increases in hunger and malnutrition, distinct from chronic hunger.
- These crises are often precipitated by supply or demand shocks in the food market, leading to price volatility.
Purpose of the Study:
- To define and differentiate food crises from chronic hunger.
- To identify the primary drivers and preventative mechanisms of food crises.
Main Methods:
- Conceptual analysis of food security definitions.
- Economic principles applied to food supply, demand, and pricing.
Main Results:
- Food crises are characterized by sudden spikes in food prices, reflecting scarcity rather than nutritional value.
- Sustained reduction in chronic hunger and prevention of short-term spikes are achievable through pro-poor economic growth and stable food prices.
Conclusions:
- Effective food policy must address both short-term hunger spikes and long-term chronic hunger reduction.
- Key strategies include fostering labor productivity via economic growth and maintaining stable food prices with ensured access for vulnerable populations.

Sources of Food Contamination
Contamination of food by microbial agents and natural toxins poses significant risks to public health. These hazards can be introduced at various points across the food supply chain, ranging from environmental sources to processing and storage stages. Understanding these contamination pathways is critical for developing strategies to ensure food safety.Seafood is particularly vulnerable to contamination through both environmental exposure and microbial colonization. Toxins from harmful algal...
Hazard Analysis and Critical Control Points (HACCP)
Hazard Analysis and Critical Control Points (HACCP) is a science-based, preventive system used globally to ensure food safety by identifying, evaluating, and controlling biological, chemical, and physical hazards throughout food production. Originally developed by NASA and the Pillsbury Company for astronaut food, HACCP is now a core component of the Codex Alimentarius.HACCP operates on prerequisite programs—such as Good Manufacturing Practices (GMPs), sanitation procedures, and supplier...
Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
Principles of Food Preservation
Food spoilage results from microbial growth, enzymatic activity, and environmental factors that gradually degrade the sensory, nutritional, and safety qualities of food. Preservation techniques aim to slow or halt these processes to extend shelf life and maintain product quality.A key concept in food microbiology is the microbial growth curve, which includes four phases: lag, exponential (log), stationary, and death. During the lag phase, bacteria adjust to their environment without significant...
What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
Methods of Controlling Food Spoilage
Food spoilage is caused by microbial growth or by chemical and physical changes, all of which affect the taste, texture, and safety of food.Temperature-Based PreservationRefrigeration at 0–4 °C slows microbial growth and enzyme activity, making it ideal for short-term storage. However, certain spoilage organisms—such as psychrotrophs like Listeria monocytogenes—can still proliferate at these temperatures. Freezing below -18 °C further slows biological processes by forming ice crystals, which...
