Safety of Foods
- United states has the safest food supply in the world
- Broad topic
- Physical, chemical, biological hazards
Today’s consumers are concerned about the food they eat
- Food safety issues are top of mind for today’s consumers, who are more likely to report an issue with food than ever before
- One third of 1000 respondents said they are more concerned about food product safety and quality than they were a year ago, about 50 percent are more concerned than they were five years ago
Safety
- More than 80% of Americans believe that brand-name foods or from chain restaurants are safe
- Although 40% have changed their food habits after the brand or chain is linked to a case of food poisoning
Myths
-
Rare burgers and raw eggs are safe to eat
-
Preservatives make foods unsafe to eat
-
Natural foods are safer than processed foods
-
Foods that look and smell alright are safe to eat
-
Cooked foods are sterile and don’t need to be refrigerated
-
Drinking alcohol protects shellfish eaters from contamination
-
HAND WASHING: Can never be emphasized enough!
Pink slime
- MYTH: “Meat glue” is used to hold chicken nuggets together
- FACT: Transglutaminase, referred to by some as “meat glue”, is an enzyme sold for almost two decades that is used mostly in food serve to bind pieces of meat together, such as a beef tenderloin or a strip of bacon to a filet.
So, what’s in a chicken nugget?
-
Chicken nuggets are in fact typically made of the same meat you see in the super market, that is, broiler meat.
-
Most chicken nuggets start as a split of chicken. You might read on the package that the product contains, “rib meat”
-
Rib meat is simply a natural extension of the breast meat. It is NOT an additive or filler.
-
ALL ingredients, including nutritional information, must be stated on the product’s label.
-
Keep in mind: all federally inspected chicken processing plants follow string food safety standards and operate under the watch of USDA inspectors at all times.
-
**Like all meat and poultry products, however, mechanically separated poultry is regulated and inspected by USDA and products containing it must declare it as an ingredient on the label
The Trade-Offs of Processed Foods
-
Processed foods are products that have been preserved
- They will not spoil as quickly as their fresh, whole raw counterparts
- Shelf-stable foods: Processes allow us to store the product at room temperature
- Primary reason for food processing: reduce or eliminate harmful microorganisms from growing in foods
-
Processed foods take more energy to produce but usually take less energy to store than fresh foods
-
Fresh, whole foods definitely more important components in a healthy diet
-
At times, processed foods are more appropriate
-
Food banks: stock, store, distribute processed foods that will not spoil rapidly
-
1st wave of supplies in response to natural disasters, like earthquakes, hurricanes, tornados, tsunamis- bottled water, processed foods
-
Military missions, hiking, space foods - convenient, easy to carry, quick energy
-
Formulated / medical foods - to provide nutritious products
Causes of Food Deterioration
- Microorganisms: bacteria, yeast molds
- Activity of food enzymes
- Infestations by insects, parasites, and rodents
- Inappropriate temperatures during processing, storage
- Gain or loss of moisture
- Reaction with oxygen
- Light
- Physical stress or abuse
- Time
Processing improves food safety
- Food industry follows defined regulations for sanitary food handling, packaging, testing
- Standards set in order to reduce risks of food-borne illnesses
- FDA: defines CGMPs, food identity, microbiological quality standards, processing methods, equipment for food manufacturers
- Food Safety & Inspection Service (FSIS) of USDA + FDA: inspect and monitor US food production, processing and marketing
The “40-140 (Danger zone)” Rule
- Foods should be held below 40 F or Above 140 F
