The greatest duty of SONOCO, to its customers, is the serving of eye appealing, appetizing, nutritionally prepared meals and to provide clean quarters in which to live. Operational sanitation and personal hygiene are the most important elements in this service. If not maintained to the highest level, these two factors may lead to foodborne illness.

Foodborne illness, commonly known as "food poisoning", is a sickness caused by eating contaminated, or improperly handled food. Contamination results from disease-carrying germs being transferred to food or water by humans, rodents or insects. Germs are bacteria that may occur naturally in food or spread to food as a result of improper handling.

TYPES OF GERMS (BACTERIA) THAT CAUSE FOODBORNE ILLNESS:

AGENT

FOUND IN

SYMPTOMS

ONSET

TREATMENT

 

Salmonella

Raw meat, poultry, egg shells, human excrement

Flu like symptoms; cramps, vomiting, diarrhea, fever

12-24 hours after eating, may last up to a week

If severe symptoms, medical treatment.

For mild symptoms, treat for dehydration; use liquids with sugar and salt (Gatorade)

Clostridium Botulinum

Improperly canned foods

POTENTIALLY FATAL; attacks the nervous system, causes respiratory failure

8-36 hours after eating. Recovery may take months

Prompt medical attention: Treatment with an antitoxin in a hospital environment

Clostridium Perfringens

Fresh vegetables, raw meats, poultry, eggs, beans, gravies

Diarrhea, stomach cramps

12 hours after eating, usually ending a day

See Salmonella above

Trichinosis (a parasitic infectious agent)

Uncooked Pork products

Vomiting, fever, muscle soreness

2-28 days after eating, can last several weeks

Medical attention in a hospital environment.

Administration of medication, including anti-inflammatories

Staphylococcus (Also known as "Staph")

Human skin. Most common source of foodborne illness

Cramps, diarrhea

3-12 hours after eating. Ends usually within 2 days

See Salmonella above

Shigella

Human excrement (feces)

Severe Dysentery

1-7 days after infection, can last a week

If symptoms severe, medical treatment including antibiotics; Milder symptoms, treat as "Salmonella

Hepatitis "A" (this is a viral agent)

Feces and urine of infected person

Flu-like symptoms, jaundice

15-50 days after infection. Lasts few weeks to several months

Medical treatment as

recommended by a physician

Cholera (Vibrio Cholerae)

Shellfish, primarily in Asian or African countries, but also in the Gulf region

Diarrhea often accompanied by vomiting, severe fluid loss that, untreated could become fatal

1-5 days after infection. Victim’s deterioration is rapid and must be treated quickly

Rehydration treatment to replace fluids,

salts and sugars lost.

Gastroenteritis (General inflammation of stomach or intestines)

Contaminated food and water supplies; also may be caused by intolerance to some foods and drugs

Appetite loss, nausea, vomiting, cramps diarrhea. Severity may vary from mild to severe and disabling, causing dehydration, collapse and shock

May appear gradually, but more often onset is sudden

Rehydration with fluids, salt and

(4tsp sugar and ¼ tsp. salt per pint of fluid.) No solid food should be eaten until symptoms subside

 

 

GERMS (BACTERIA):

AGENT

FOODS IMPLICATED

HOW IS IT SPREAD TO FOODS?

Salmonella

Poultry, Poultry salads, meats, meat product, mild shell eggs, custards, protein foods

Contamination occurs by use of unsanitary cutting boards, work surfaces, utensils and unwashed hands

Clostridium Botulinum

Improperly canned foods, garlic products packed in oil

Contamination occurs by eating improperly canned or preserved foods which are contaminated with "clostridium botulism"

Clostridium Perfringens

Meat boiled, steamed, braised, stewed, roasted at low temperature for a long time, or cooled slowly before serving

Contamination occurs through the handling of food with unwashed hands and by eating food cooked inadequately, cooled and improperly reheated

Trichinosis

Uncooked or raw pork

A parasitic infectious agent which lives inside a host (roundworms, etc.) and found in pork. Infection occurs when the pork is undercooked

Staphylococcus

Warmed over foods, ham, other meat products, custards, potato salad, protein foods

Occurs in the nose, throat, infected cuts, boils, burns and unwashed hands. It spreads through contact with infected skin, coughing and sneezing

Shigella

Potato, tuna, shrimp, turkey,or macaroni salads, lettuce, moist and mixed foods, dishes with mayonnaise

Contamination occurs from unwashed hands to dishes, silverware, raw product and moist prepared foods.

Hepatitis "A"

Found in feces or urine of infected persons.

A viral (infectious) agent transmitted by infected persons who do not wash hands after using rest room. Can be transmitted to food and water

Cholera (Vibrio Cholerae)

Eating infected shellfish

By eating infected shellfish

Gastroenteritis (General inflammation of stomach/intestines)

Rice and rice dishes, custards, seasonings, dry food mixes, spices, puddings, cereal products, sauces, vegetable dishes, meat loaf, dishes with mayonnaise

Using correct cooking methods (temperatures and holding procedures) and correct personal hygiene and sanitary procedures in handling foods.

HOW DO GERMS (BACTERIA) GROW?

  1. Time
  2. The longer a food stays in an improper environment, the more the bacteria reproduce. One germ can reproduce 281,000,000,000 more in a 24-hour period.

  3. Temperature
  4. Bacteria grow inside the 45 degrees (F) to the 140 degrees (F) range. They grow slowly over 140 degrees (F) and are killed rapidly at 165 degrees (F) and higher. BACTERIA GROW MOST RAPIDLY AT THE HUMAN BODY TEMPERATURE: 98.6 DEGREES (F).

  5. Environment

Food, the human body and food service equipment all provide a perfect environment for growth and survival of bacteria if the right temperature is present and given adequate time.

 

 

HOW DO WE PREVENT FOODBORNE ILLNESS?

It is impossible to keep harmful bacteria out of the food we eat because they are everywhere. They are in our breath, on our skin, hands, hair and mouths, and on our clothing. But, there are a number of ways to prevent bacteria from causing illness:

Personal Health and Cleanliness

PERSONAL HYGIENE

WASHING HANDS

Shower daily

Wear clean uniforms daily

Before beginning work

Before handling food

Keep hair neat, trimmed

Wear cap, hair restraint

When moving/handling one food to another

After using the toilet

Keep fingernails trimmed and clean

Do not wear jewelry, except watch

After eating and smoking

After handling garbage

After coughing, sneezing

After touching face, hair

As stated, wash hands often using warm water and soap for at least thirty (30) seconds. Dry hands on disposal paper towel or a hot air blower.

KITCHEN SANITATION : Clean

All food preparation equipment

Slicers, grinders, mixers, can openers

Juice dispensers, milk dispensers

Counter tops

Refrigerators, storage freezers, coolers

Pie safes, microwave ovens, and cutting blocks

Wash all surfaces, areas with hot soapy water immediately after use. Check cracks, joints and edges for food particles. Rub wooden surfaces with lemon rind to eliminate odor.

WASHING DISHES

BY HAND

MACHINE

Scrape dishes and utensils thoroughly to remove particles

Remove all food from dishes before putting in machine

Wash in soapy water at 110-120 degrees (F).

Add one tsp. of bleach per 5 gal. of water for sanitizing

Use cleaning and sanitizing chemicals

Change water often

Water temperature should be 180 °F. Check water temperature and chemicals often

DRYING DISHES

Let dishes & utensils air dry. Towels contain bacteria

Store glasses top down, grip by the base, or handle

Handle dishes underneath. Do not hook thumb on edge.

Grip silverware by the handle

Cutting boards should be sanitized after each use

Discard boards with deep gouges

COOKING

The surest way of reducing bacterial growth is through the control of temperature:

TEMPERATURES

(In Degrees F)

ITEM

10

Storage of frozen foods

32-40

Refrigerator temperature

40

Bacteria growth slows. Get cold foods to this temperature quickly and keep it there

41-139

Bacteria growth occurs in this range. (Greatest growth at 98.6°)

140

Bacteria growth stops in most foods

165

Trichinosis is killed in pork cooked to this internal temperature for at least three minutes. Considered to be the safest internal temperature for most cooked foods
