Handling Food Safety In The Restaurant
Most people rarely get sick from contaminated foods because their immune systems are
strong enough to protect them. But when harmful bacteria multiply beyond safe limitsdue to unsafe food handling or lack of refrigeration, that's when food poisoning strikes.
When the immune system is impaired by sickness, age, or other factors, food poisoning is
also more likely.
Handle food as little as possible.
Throw away plastic gloves after one use.
eep fingers away from mouth, hair, face, skin and other parts of
the body.
!se the rest room sink or the hand"washing sink in the food
preparation area for washing hands, not the food preparation sink. Wash fresh produce under running water before it is served either
raw or cooked.
Thaw fro#en foods in the refrigerator, under cold running water, or
as part of the cooking process.
$repare precooked fro#en foods e%actly as the directions state. Have foods ready at serving time but not any longer than necessary
before serving time.
&o not leave cooked foods at room temperature.
lean and saniti#e food preparation surfaces between different
types of raw food products (beef, pork, poultry, etc.) and between
the preparations of raw products and ready to eat products.
*void placing cartons or bo%es on surfaces used for food
preparation.
Wipe food contact surfaces with clean cloths, which are used only
for that purpose. eep kitchens free of clutter.
eep worktables clear and clean while in use.
Wash and put away e+uipment that is not being used.
Wash and saniti#e flatware or other utensils, which fall to the floor.
&o not taste foods with any utensil used either to mi% or stir foods.
&o not use fingers to sample food. *lways use a clean spoon.
!se clean tongs, scoops, forks, spoons, spatulas, or other suitable
utensils to handle food.
$ick up and hold all tableware by the handles.
tore tableware away from dust. $rovide straws either individually wrapped or from an approved
dispenser.
-ce machines should be covered. -ce should be transferred to
serving containers using approved scoops. ever use hands, cups,

or glasses to scoop ice. eep scoops protected when not in use. &o
not store food items on ice used for drinks.
!se a spoon or other suitable utensil to remove any serving or
mi%ing spoon that falls into the food.
When handling plates and trays do not touch eating surfaces with
fingers.
ommon /uestions0
Are restaurant workers required to wear hairnets?
*nswer0 Hairnets are not re+uired, but food handlers are re+uired to wear some sort of
hair restraint. -t can be a cap, visor or a hair restraint of some sort.
Is it ok to use dented cans in the restaurant?
*nswer0 Because dented cans can have holes or compromised areas, they are not safe and
should not be used. *ll it takes is a microscopic hole in these cans to set up dangerous
bacteria like botulism and make your customers sick.
Why aren't food workers allowed to have drinks in the food re area?*nswer0 -n a hot kitchen drink containers may sweat on the outside because of the heat.
When you put the drink up to your mouth and then set the drink down on a table where
you are preparing raw food, the bacteria from your mouth, can contaminate the preptable. *lso, most food handlers usually forget to wash their hands after they've taken a
drink, contaminating their hands, which, in turn contaminates the food.

How to reare for a Health Insection
seeing your health inspection as help rather than a hindrance could be good forbusiness.
Section !" What to #o $efore an Insector %isitsWithout a health inspection, your restaurant could fall victim to a food borne"illnessoutbreak that could ruin your establishment's reputation and even force you to close your
doors.
The proper strategy for a successful health inspection is to be ready for an e%amination at
any time. This means that you and your managers should become inspectors and conduct
weekly, in"house e%aminations before health inspectors arrive.
1 When conducting a self"assessment, you should use the same form"or a similar form"
that your health department uses and put yourself in the health inspector's place.
1 2our self"inspection should include walking into your establishment from the outside to
get an outsider's impression. !sing the outlet checklist.
1 *fter you inspect your operation, hold a 34"minute briefing with kitchen5outlet staff to
review any problems. This step will help convey the importance of food safety to staff
members.
1 -f your staff includes employees for whom 6nglish is a second language, ask a bilingual
employee to translate the findings to them so they also understand how importantcleanliness is to the success of your restaurant.
1 2our self"inspection priorities for kitchen5outlet employees should include0 food
temperature, awareness of food types and hand washing.
1 Temperature guidelines include checking the temperature of products when they arrive,
when they are stored and when they are served. &oing this will reduce food borne"illnessoutbreaks by 74 percent.
1 8ood"type guidelines are divided into three categories0 beef and beef blood9 chicken9and all other types of food. These three categories can never touch each other during
preparation.
1 The importance of hand washing should be re"enforced by posting signs at all kitchen
sinks and in employee restrooms.
1 Train your managers to ensure that they are up"to"date on the latest food"safetytechni+ues. :estaurant employees are re+uired to attend the food"safety training program.
1 :eview your local health code for any special, local re+uirements.

Now that you know what to do when a health inspector arrives. Be warned that
examiners usually arrive unannounced, so you'll want to be ready on any occasion, even
during a rush.
Section &" What to #o When a Health Insector %isits
&on't panic when an inspector arrives. Think of this as a learning opportunity that willbenefit your operation by making it as safe as possible.
To make an inspection as pain"free as possible, you should0
1 *sk to see the inspector's credentials first. -n some cases, people have tried to pass
themselves off as health officials. -f you're unsure of the person's credentials, call the
local health department or the inspector's supervisor for verification.
1 &o not refuse an inspection. The e%aminer will likely get an inspection warrant that you
can't refuse and the e%amination will be even more thorough.
1 Tag along with the inspector and take notes of any violations he or she finds. This gives
you the chance to correct simple problems on the spot and the e%aminer will note your
willingness to fi% problems.
1 :efrain from offering any food or any other item that can be misconstrued as an attempt
to influence the inspector's findings.
1 *fter the e%am, be sure to sign the inspector's report. igning it doesn't mean that you
agree to the findings9 it only means that you received a copy of the report.
1 *sk the inspector to e%plain his findings to you and your staff and offer suggestions on
areas that need improvement. 6ven the cleanest restaurants sometimes contain health"
code violations.
Section " What (ou )an #o if (ou Are )ited
Here's what you can do to limit the damage of an adverse health inspection0
1 8i% small problems during the inspection to let the e%aminer know you are willing towork with him or her.
1 -f you don't understand the violation, ask the health official to e%plain. &on't beconfrontational.
1 -f you disagree with the inspector's findings, keep +uiet for the time being and appeal
the decision later. 2our health inspector should be your ally. He or she can improve the+uality of your cuisine and save you from the devastation of a food borne"illness incident.

How to $uild a $etter Relationshi with (our Health Insector* +The need for good
co,,unication with health insectors-
-n the foodservice industry, effective food safety and sanitation programs are an essential
element of every successful operation. The relationship you build with your local health
inspector can be of great benefit to your food safety and sanitation programs and thushelp you please your customers. pending a little +uality time and effort to improve
communication with your health inspector can be very beneficial to your business and
can help eliminate costly misunderstandings.
The ultimate goal ;of a health inspection< is to protect the public and prevent people from
becoming ill. either the health department nor the restaurant ever wants a customer tobecome sick. -t's not good for the restaurant or the Health &epartment. Therefore, the
goal of health inspections is =T to catch something or get somebody into trouble, but toprevent illness.
ince this is clearly a common goal shared by both entities, the ne%t step is to assure
effective communications and build a strong relationship in order to make that goal a
reality together. Health inspections involve much more than a simple look around yourrestaurant, says teven >rover, the ational :estaurant *ssociation's ?ice $resident of
Health and afety :egulatory *ffairs. :estaurateurs who have successful interaction with
their local health "" inspection agencies and run clean, safe operations agree that theprocess does not begin when an inspector arrives at the restaurant, armed with a list of
things to scrutini#e. The process begins before the inspection with preventative measures
such as safe, clean practices in the operation day in and day out. -t also involvesdeveloping avenues of clear communication and a mutually respectful relationship with
the people who work for the health department.
Be polite
There is a reason why @first impressions are lasting impressions@ is a popular e%pression.
-t is very important that you treat your health inspector with respect from the verybeginning. Those first few minutes help to set the tone for the ne%t hour and for many
inspections to come. 8or this reason, it is important to greet your inspector professionally
and give him5her respect, even if you are busy. 2ou should treat the inspector as youwould any other guest in your establishment9 after all we are the hospitality industry. 8or
one thing, don't get angry if an inspector shows up during a mealtime, says >rover, who
is also a former ?irginia health inspector. @>enerally inspectors are there to see youprepare food,@ he says, @so sometimes you should e%pect an inspection at mealtimes.@
When the inspector arrives, greet him or her pleasantly and ask to see his or her
credentials. -t is important that you establish the basis for the inspection and the
authenticity of the inspector from the very beginning. Be professional, cooperative,
8/12/2019 Tips of Food Handling
6/36
friendly and open, says >rover. &on't offer any favors or food, and don't be
argumentative or defensive. ever argue with a health inspector during the inspection. -f
there's a problem, try to work it out with the inspector in a professional manner and don'ttake the inspector's observations or violations personally. -f you can't work it out during
the inspection or during the post inspection discussion, remember you can always call the
inspector's supervisor and ask for clarification later.
*s :adke advises, @&on't take the inspection personally. -t is not a personal attack. -t isthe Aob of the inspector to find errors and he or she may find
some things that need to be corrected. The nature of the inspection is to verify that your
operation is taking the necessary precautions to help avoid a serious food"related illness
outbreak.@
?ictoria &ecker, 8oodservice &irector of /uality *ssurance for lyde's :estaurant
>roup says that @=perators should take the health inspectors seriously. They are
forecasting and preventing future problems for the restaurant.@ 8or this reason, &eckersays that her company takes a proactive role with the inspectors and welcomes the health
inspectors into its restaurants. 8urthermore, &ecker adds, @we correct most errors orinspector observations on the spot.@
*ccompany your health inspector
*fter you greet your health inspector9 show him5her that you take a great interest inproviding your customers with safe and high +uality food by accompanying him5her
during the inspection.
@-t is nice when the person in charge is able to go around with the inspector during an
inspection. -f not the manager or the assistant manager, then at least one of the staff.
Because inspectors usually show up unannounced, it is perfectly understandable ifrestaurant operators are too busy to accompany us,@ says :adke. *ccompanying the
inspector during the inspection shows the inspector that you're interested in the processand in correcting any problems immediately.
=bserving the inspection allows you to better understand the basis for the
recommendations that are being made. @* picture is worth a thousand words,@ :adke
notes. @Having violations physically pointed out gives you a better understanding of theproblem because the inspector is able to show why something is a violation.@
*s you walk around your facility with your environmental health specialist, there are
several things that you can do to demonstrate that you take public health seriously. Tobegin with, bring a note pad and write down any observations that your health inspectormakes. This allows you to have your own record of the recommendations for later
reference. -t also shows your inspector that you are serious about implementing the
necessary changes over the long term and not Aust while the inspector is there.
-f you don't understand something that your inspector says, or why something is a
violation, +uestion the inspector immediately. =pen communication is the best way for
you to understand the regulations and what you can do to fully comply with them. -t also
8/12/2019 Tips of Food Handling
7/36
is a good way to become educated and show him5her that you want to improve your
knowledge of food safety and regulations.
eeping foods at safe temperatures is critical to food safety, so be prepared to taketemperatures of foods along with the inspector. This demonstrates to the inspector that it
is common practice for you, and that you know how to do common practices. :adke
notes that when an operator is not aware of critical issues or if he or she can't give general
information about critical temperatures, it gives the health inspector the impression thathe5she is not dealing with a responsible operator. 3f however, you show your inspector
that these practices are commonplace, you are immediately eliminating any doubt
regarding your professional food safety knowledge.
now the rules
6ven though at times the rules seem to change ever so +uickly, and the interpretation of
the individual health inspector may be a little different than the previous one, there are
some effective means to ensure a clean restaurant, which will lead to a satisfactoryinspection. 8irst, it is very important to know what the health inspector is looking for
when conducting an inspection. -f your restaurant has a /uality *ssurance Manager9 thatperson must understand key food safety issues in order to ensure safe food preparation
and handling to, in turn, prepare for a health inspection. To gain a better understanding ofwhat is e%pected, get a copy of the regulations from your local health agency and make
an effort to learn the re+uirements. *lso, utili#e the knowledge of your health inspector
and ask +uestions where you may be uncertain on how they may interpret the regulation.onsider inviting your health inspector to your restaurant to give an educational
presentation on a specific food safety or regulatory is sue. =pen communication and
training will better prepare you for inspection day and help you to better understand howthe inspector is evaluating your restaurant.
orrect mistakes
:adke says that one thing that gives him the impression that he is dealing with an
irresponsible operator is when he sees that no efforts have been made to correct code
violations, even after repeated violations are observed. &o not leave this impression withan inspector. *s soon as he or she states a violation, do what you can to correct it or start
corrective actions immediately.
8or e%ample, if a health inspector cites that the three compartment sink's saniti#ing
solution does not meet the minimum concentration re+uirement, don't Aust nod your headin agreement and write it down. -nstead, have someone immediately drain the sink and
prepare the saniti#ing solution at a proper concentration in order to saniti#e e+uipmentproperly and correct the observation. This shows your inspector that you areconscientious about the recommendations he5she gives and that you want to correct them
as soon as possible. 8rom the perspective of the health inspector, if you are not even able
to make the small, simple changes right away, he5she is likely to think that you will notmake larger9 more critical changes later.
-n addition to making simple corrections on the spot, it is also important to relay
information from inspections to employees immediately. 8or e%ample, if the health
inspector notices an employee has returned from the dumpster area without washing her
8/12/2019 Tips of Food Handling
8/36
hands and begins to prepare salad, immediately take the employee aside to correct the
situation. *lso follow up with general employee training on proper hand washing
techni+ues at a later time to assure long term compliance.
=pen up communication
*fter your health inspector has completed his written report, take the time to sit down
with him or her to go over what was observed during the visit. @=pen communication ise%tremely important, so do not be afraid to ask +uestions. 2our professional demeanorwill facilitate that communication,@ says >rover. This is a perfect time to impress on your
health inspector that food safety is a top priority for your operation. >rover adds, @if you
get written up for any violations, make sure you fully understand what the violations are
and how to fully correct them.@ arry caglione agrees. @This is the opportunity to learnfrom each other to meet our shared obAective of protecting the public.@

by theU.S. Public Health Service
The U.S. Public Health Service classifies moist high!protein and"or
low acid foods as potentially ha#ardous. High protein foods consist inwhole or in part of milk or milk products shell eggs meats poultryfish shellfish edible crustacea $shrimp lobster crab%. &aked or boiled

Who is at risk?
'nfants young children pregnant women the elderly and people whoare chronically ill have a greater risk of developing a foodborne illness
because their immune systems may not be able to fight off the
bacteria and viruses that cause the illness. Those at greater riskshould avoid consuming potentially ha#ardous foods that are raw or
not fully cooked. 'nfants and children are more
vulnerable because their stomachs produce less acid making it easier
for bacteria and viruses to multiply. Pregnant women are at riskbecause a fetus does not have a fully developed immune system.

The elderly are more susceptible to foodborne illnessbecause of inade(uate nutrition lack of protein in their diets or poor
blood circulation. People who are chronically ill or who takemedication that affects their immune system are also at greater risk of
becoming sick from a foodborne illness. This could include people withcancer diabetes A')S patients or people who take antibiotics.

Eeep packages of raw meat and poultry separate from other foods
especially produce items.
Use plastic bags to enclose individual packages of raw meat and
poultry. Frab a few e2tra while in the produce section and putthese on the bottom of the cart.
-ake sure meat poultry and dairy products are refrigerated as
soon as possible after purchase. The grocery store should be yourlast errand when shopping.
Place refrigerated foods in a cooler especially in hot weather for
the trip home.
Purchase canned goods that are free of dents cracks or bulging
lids.
+heck that all food packages are intact ! no broken seams or tears.
Select produce that is freshB 5atch for signs of aging and decay
such as mold or brown leaves and stems. Cook for glossy skin and
green leaves.
Select food packages with longest period of time until e2piration.

&is for &ood
The nutrients available in food often determines whethermicroorganisms will grow. 5hile some microorganisms have
simple nutrient re(uirements some pathogens re(uire a comple2diet including proteins.
-oist protein!rich foods such as meat milk eggs and fish are
potentially ha#ardous. That is they are most likely to causefoodborne illness because htey are a food source for pathogenic
bacteria and can support growth of these bacteria.

The degree of acidity or alkalinity $base% of a substance is measured
by its pH. pH is measured on a scale from 7 to 6;.7. An environmentwith a pH of >.7 is e2actly neutral. *oods with a pH below >.7 are
acidicI a pH above >.7 is alkaline. The lower the pH the higher the
acidityI the higher the pH the lower the acidity.
&acteria grow best in an environment that is neutral or slightly acidic.
-ost bacterial growth is inhibited in very acidic conditions. That is why
acidic foods like vinegar and fresh fruits $especially citrus% seldom
provide a favorable climate for pathogenic bacteria. -ost bacteria willnot growat pH levels below ;. because the environment is tooacidic. -icroorganisms thri$ein a pH range between . and >.=.

canned o2ygen is e2cluded from the environment. Thereforegrowth of aerobic organisms is controlled and the food is
preserved. Such foods are shelf stable and do not re(uire
refrigeration until they are opened.
Some microorganisms will grow only in anaerobicconditions $in
the absence of o2ygen%. &otulism a rare type of foodborne illnessis caused by a specific type of bacteria called clostridium botulismthat grows only in anaerobic conditions. 'mproperly preserved
home canned foods are a typical source of botulism. Home canneditems can not be used in foodservices.

Ais for Aoisture
All microorganisms must have an abundant supply of water to grow.Perishability of a food is related to the moisture content and the
water activity level.
Aoisture contentis the amount of water in food e2pressed as a
percentage. 5ater activity $ aw% is the amount of water available foruse and is measured on a scale of 7 to 6.7. &acteria yeast and
molds multiply rapidly with a high water activity level above 7.J.-eat produce and soft cheeses are e2amples of foods with awin this
range $between 7.J and 6.7%.
*oods preserved with salt or sugar such as beef 0erky or 0ams and
0ellies have a lower aw because salt and sugar deprive
microorganisms of water and inhibit their reproduction. Theseproducts are shelf!stable $i.e. they do not need refrigeration unless
opened%. Pathogenic bacteria have difficulty growing in foods such as
dry noodles flours candies and crackers where awis below 7.J=.
