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?
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.
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).
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 |
