Describe the five food groups, diseases from their deficiency, and their functions. Also, list four types of PPE and how to encourage farm casuals to achieve them.

Here are the answers to the questions:

Question Five

a) Five food groups that constitute a balanced diet are:

• Carbohydrates
• Proteins
• Fats/Lipids
• Vitamins
• Minerals

b) One nutritional disease caused by the deficiency of each food group:

• Carbohydrates: Marasmus (due to severe energy deficiency)
• Proteins: Kwashiorkor
• Fats/Lipids: Essential fatty acid deficiency
• Vitamins: Scurvy (Vitamin C deficiency)
• Minerals: Anemia (Iron deficiency)

c) Two functions of each food group:

• Carbohydrates:
  1. Primary source of energy for the body.
  2. Provide fiber for digestive health.
• Proteins:
  1. Build and repair body tissues.
  2. Produce enzymes, hormones, and other body chemicals.
• Fats/Lipids:
  1. Store energy for long-term use.
  2. Insulate the body and protect vital organs.
• Vitamins:
  1. Act as coenzymes in various metabolic processes.
  2. Support immune function and vision.
• Minerals:
  1. Form strong bones and teeth (e.g., calcium).
  2. Regulate body fluids and nerve function (e.g., sodium, potassium).

Question Six

a) Four types of indicated safety gear (Personal Protective Equipment - PPE):

• Safety gloves
• Safety boots
• Eye protection (e.g., safety glasses)
• Hard hats

b) How to encourage achievement of the following by farm casual workers:

i) Maintenance of PPEs:
Encourage workers through regular training on proper cleaning and care of PPE, emphasizing its role in preventing injuries. Provide clear instructions and accessible resources for maintenance.

ii) Storage and Inspection of PPEs:
Provide designated, clean, and easily accessible storage areas for PPE. Train workers on how to conduct pre-use inspections and implement a system for reporting damaged or worn-out equipment for replacement.

c) Four safety considerations when repairing a barbed wire fence:

1. Wear appropriate PPE: Always use heavy-duty gloves, long-sleeved shirts, long pants, and safety glasses to protect against cuts, punctures, and eye injuries from the sharp barbs and wire.
2. Check for tension: Barbed wire can be under significant tension. Carefully release any tension using appropriate tools before cutting or manipulating the wire to prevent sudden recoil and injury.
3. Handle with care: The barbs are extremely sharp. Always handle the wire carefully, keeping hands away from the sharp points to avoid deep cuts and punctures.
4. Use proper tools: Employ specialized tools such as wire cutters, fence stretchers, and pliers designed for barbed wire to ensure safe and efficient repair, reducing the risk of accidents.

Question Seven

a) Two forms of pollution generated on an agricultural farm:

• Water pollution (e.g., from fertilizer and pesticide runoff)
• Soil pollution (e.g., from accumulation of agricultural chemicals)

b) Two roles of NEMA in environmental management:

• Develop and enforce environmental policies, laws, and regulations.
• Conduct and oversee Environmental Impact Assessments (EIAs) for development projects.

c) Distinguish between the following terms used in wastes management:

i) Non-biodegradable wastes and Biodegradable wastes:
Biodegradable wastes are materials that can be broken down naturally by microorganisms into simpler, harmless substances within a relatively short period (e.g., food scraps, plant matter). Non-biodegradable wastes are materials that cannot be broken down by natural biological processes or take an extremely long time to do so, persisting in the environment (e.g., plastics, glass, metals).

ii) Hazardous wastes and non-hazardous wastes:
Hazardous wastes are wastes that pose a substantial threat to public health or the environment due to their toxic, corrosive, flammable, reactive, or infectious properties (e.g., pesticides, used oils, medical waste). Non-hazardous wastes are wastes that do not pose an immediate threat to human health or the environment and are generally safe for conventional disposal (e.g., household garbage, paper, garden waste).

d) Four best methods of managing non-biodegradable wastes on an agricultural farm:

1. Reduce: Minimize the generation of non-biodegradable waste by choosing products with less packaging or opting for reusable alternatives whenever possible on the farm.
2. Reuse: Find alternative uses for non-biodegradable items on the farm before discarding them, such as repurposing plastic containers for storage or old tires for planters.
3. Recycle: Separate recyclable non-biodegradable materials like plastics, glass, and metals from other waste streams and send them to appropriate recycling facilities.
4. Proper Disposal: Ensure that any non-recyclable and non-reusable non-biodegradable waste is collected and disposed of in designated landfills or approved waste management facilities to prevent environmental contamination.
