Introduction to Agriculture and Food Systems Flashcards

Chapter 12: Food Production and Safety

Overview of Chapter 12

  • Focus on the journey of food from production to consumption.

  • Topics to be discussed:
      - GMOs (Genetically Modified Organisms)
      - Use of antibiotics and hormones in food
      - Organic foods
      - Agricultural practices and sustainability

Key Concepts

GMOs (Genetically Modified Organisms)
  • Definition: Organisms whose genetic material has been altered using genetic engineering techniques.

  • History: Increased presence and discussion over the last decade, although they have been around since the 1990s (over 30 years).
      - First GMOs aimed to increase shelf life, enhance nutritional content, and reduce pesticide usage.

  • Current Role: GMOs play a crucial role in global food supply, helping to feed populations beyond the U.S.

  • Facts to know:
      - Not inherently new or frightening, but often misunderstood
    the importance of education about GMOs.
      - Benefits include:
        - Reduced need for pesticides.
        - Improved shelf life of products.
      - Environmental role in increasing food production.

Food Waste in the U.S.
  • Significant amounts of food waste occur in various sectors, especially restaurants and grocery stores.

  • Sustainability Impact: Reducing waste can improve overall sustainability of food systems.

Food Marketing Techniques and Target Demographics
  • Food marketing predominantly targets young adults, college students, and children.

  • Common advertisements seen:
      - Processed foods, fast food restaurants
      - Limited advertising for fresh produce or healthy options.

  • Observation: Most food advertisements favor processed options over healthier alternatives.

Agricultural Practices
  • Most foods are grown on family-owned farms.
      - Family farms are often passed down through generations.

  • Food production is not limited to local consumption; a considerable amount of food is exported globally to help feed other countries.

Food Production Process
  1. Farm: Where crops are grown.

  2. Processing Facility: Where food is prepared (cleaned, cut, packaged).

  3. Distribution: Moving food from processors to sellers (often involves trucking).

  4. Retail Sales: Grocery stores and restaurants are primary sellers.

  5. Consumer: The end-user who purchases and consumes the food.

  • Contamination Risk: Can occur at any stage of this process, raising food safety concerns.

Challenges in Farming
  1. High Costs: Farmers face significant investments while consumers demand low prices.

  2. Competition: Competing with domestic and international producers.

  3. Natural Disasters: Events like droughts and hurricanes can drastically affect food availability and prices.

Top Food Crops in the U.S.
  • The three main crops produced: Corn, Soybeans, and Wheat.
      - Corn:
        - 70% used for animal feed.
      - Soybeans:
        - 70% for animal feed; rest used for soy products (tofu, soy milk).
      - Wheat:
        - 70% used for human food; 22% for animal feed; remainder for regenerating crops.

Animal Production
  • Focus on three primary animals: Cows, Pigs, and Chickens.

  • Raising livestock requires much more land and water compared to plant-based foods.

  • Livestock contribute to higher greenhouse gas emissions, particularly beef, which is the most resource-intensive.

Exporting and Importing Foods
  • Exporting: Sending U.S.-grown food to other countries, benefiting global food security, but also exporting unhealthy habits.
      - Pros: Supports global agriculture and provides income to farmers.
      - Cons: Spreads unhealthy consumption patterns.

  • Importing: Bringing foods produced in other countries into the U.S.
      - Reasons for imports:
        - Year-round availability of products (strawberries in winter).
        - Cost-effective production in other countries.
      - Concerns include environmental impacts and the ability to inspect all imports for safety.

Sustainability in Food Systems

  • A sustainable food system ensures future generations can adequately feed themselves.

  • Three E's of Sustainability:
      1. Environmentally Friendly: Protect soil, water, and promote biodiversity.
      2. Economically Viable: Affordable food for consumers.
      3. Equitable and Ethical: Access for all to nutritious foods and humane treatment for both workers and animals.
      - Current practices often fail to meet these sustainability goals.

Improving Sustainability
  • Community-supported agriculture (CSA): Local farms supply seasonal products to consumers.

  • Farmers markets: Local opportunities to purchase directly from producers.

  • Contracts with grocery stores: Local produce sold in stores promotes local consumption.

Environmental Concerns in Agriculture
  1. Soil Degradation: Unsustainable farming leads to loss of soil health.

  2. Energy Use: Farming and transportation processes contribute to environmental strain.

  3. Water Use: Droughts or overuse affect agricultural sustainability.

  4. Food Waste: Significant waste occurs at various points of consumption.

Consumer Actions for Sustainability

  • Changing consumption habits, such as reducing meat intake, contributes to lower environmental impacts.

  • Supporting local, sustainable food sources through informed choices and purchases.

Hot Topics in Food Production

Hormones in Beef Production
  • Use of hormones (bovine growth hormone) is approved only for cows.
      - Intended to boost milk and meat production.
      - FDA asserts no negative health effects from consuming hormone-treated beef or milk.

  • Hormones are species-specific, meaning they do not work the same way in humans and cattle.

Antibiotics in Animal Production
  • Used to treat sick animals and prevent illness in herds.

  • Overuse in livestock can lead to antibiotic-resistant bacteria, posing a public health risk.

  • Farmers often follow protocols to ensure antibiotic-treated animals are removed from the food supply until it’s safe for consumption.

Pesticides and Organic Foods
  • Pesticides: Used to control pests and protect crops; can cause harm if misused.

  • Organic farming uses fewer pesticides and prohibits some chemical treatments.

  • Organic doesn’t guarantee 100% pesticide-free; some pesticides are allowed.

Organic Foods Overview

  • Definition of Organic: Grown without bioengineering and irradiation and with fewer pesticides.

  • Label Interpretations:
      - 100% Organic: Entire product is organic.
      - Organic: At least 95% of ingredients are organic.
      - Made with Organic: 70% organic ingredients.

  • Pros and Cons:
      - Fewer pesticides used, often more expensive.
      - Not necessarily more nutritious overall.

Dirty Dozen vs. Clean 15

  • Dirty Dozen: Fruits and vegetables with the most pesticide residues, best bought organically (e.g., spinach, strawberries).

  • Clean 15: Those with the least pesticide residues; no need to buy organic (e.g., pineapples, avocados).

  • Importance of knowing these groups for informed purchasing decisions.
