Many countries now offer development programs. Removing barriers to financial credit Providing access to time-saving technologies Providing appropriate training to promote self-reliance Teaching management and marketing skills Making health and day care services available Forming women's support groups Providing information and technology to promote planned pregnancies
Development programs that many countries now offer
households must qualify bases on their income, expenses and assets
How do you receive SNAP?
households with lower income receive higher benefits up to a particular maximum. Most adults are required to work or take part in an employment or training program
How does SNAP work?
Any student in a participating school can get an NSLP lunch regardless of the student's household income Eligible students can receive free or reduced-price lunches. Free lunches are available to children in households with incomes at or below 130% of poverty. Reduced-price lunches are available to children in households with incomes 130% to 185% of poverty.
How does the National School Lunch Program Work?
homelessness, people not wanting to use welfare or charity, elderly health problems, not enough community food sources.
Other causes of food insecuity
- pesticides can accumulate in body fat of animals -they can linger in environment -banned in one country can still pose global impact -greatest risk of pest is by those that can build up in food chain

Food security is a problem of what?

-Less synthetic pesticide, hormone, and other chemical fertilizer residues in foods and waterways -Beneficial to the environment: Improved soil fertility and crop diversity; increased water and energy conservation -Farmers may follow more humane animal welfare standards -May be higher in certain phytochemicals
What are some advantages of certified organic foods?
1. The ready availability of nutritious and adequate safe foods. 2. The ability to acquire personally acceptable foods in a socially acceptable way.
What does food security include?
the collection of wholesome food for delivery to hungry people ex: collecting canned or boxed food from supermarkets, rescuing surplus food from restaurants.
What is food recovery?
Meals and snacks provided through CACFP can be especially important to working parents, playing a role in improving day care quality and making day care more affordable for recipients. In child care centers, meals and snacks are reimbursed at either free, reduced-price, or full rate, depending on children's family income—similar to the reimbursement structure for school meals.
What is the importance of the child and adult care food program?
Households with children and a single mother or single man, women and men living alone, households headed by black, non-hispanics, and hispanics, low-income households, and households in rural areas.
Where are food security rates the highest?
Asia and the Pacific
Where do most malnourished people live?
children are rapidly growing
Why are children most at risk for malnutriton?
GRAS List

Clostridium botulinum
a microbial food agent; Grows in warm anaerobic environment that is low-acid, produces a neurotoxin that causes muscle paralysis; improperly canned foods, herbs stored in oil. Honey can contain spores which can grow in gut of small children < 1 year
Mold
a microbial food agent; can produce aflatoxins which are liver toxins and known to be carcinogenic and can be lethal in large amounts; moldy peanuts, beans, grains like wheat and corn.

when foods are prepared, cooked, or stored improperly.
how does food poisoning occur?
Use soap and warm water (soap kills bacteria) Keep hot foods hot (above 140F), keep cold foods cold (below 40F) Refrigerate leftovers promptly Prevent cross-contamination between raw and cooked foods knives, cutting surfaces, platters used to marinate or season, storage in frig Do not prepare food if you have a skin infection or infectious disease When in doubt, throw it out Discard food from cans that leak or bulge Cook all meat and poultry to 160°F or higher Wash fruits and vegetables thoroughly before eating

what are conditions that promote microbial growth?
heat treatments, canning, low temp storage, chemical preservatives, fermentation, control of water content
what are some control measure in food industries?
-USDA makes no claims that it is safer or more nutritious -More expensive -Tend to spoil faster, because they contain no preservatives -May be fertilized with improperly composted animal manure containing potentially harmful organisms, e.g., E. coli -May be cross-contaminated with pesticides from nearby conventionally sprayed fields
what are some disadvantages of certified organic foods?
vitamin A deficiency, iron deficiency anemia, and iodine deficiency.
