Anestimated43billionpoundsoffoodwerewastedinUSretailstores
in2010.Thisisparticularlydisconcertinggiventhatin2016,12.3
percentofAmericanhouseholdswerefoodinsecure.Mostoftheloss
inretailoperationsisinperishables,includingbakedgoods,produce,
meat,seafoodandpreparedmeals.TheUSDAestimatesthat
supermarketslose$15billionannuallyinunsoldfruitandvegetables
alone.Unfortunately,wastefulpracticesintheretailindustryare
oftenviewedasgoodbusinessstrategies.Someofthemaindriversfor
foodlossatretailstoresinclude:overstockedproductdisplays,
expectationofcosmeticperfectionoffruits,vegetablesandother
foods,oversizedpackages,theavailabilityofpreparedfooduntil
closing,expired“sellby”dates,damagedgoods,outdatedseasonal
items,overpurchasingofunpopularfoodsandunderstaffing.

DonationAct,signedintolawin1996,provideslegalliability
protectionforfooddonorsandrecipientsandtaxbenefitsfor

intheprotectionsitoffersremainslow.
USrestaurantsgenerateanestimated22to33billionpoundsoffood
wasteeachyear.Institutions一includingschools,hotelsand
hospitals一generateanadditional7to11billionpoundsper
year.Approximately4to10percentoffoodpurchasedbyrestaurants

managementandextensivemenuchoices.AccordingtotheCornell
UniversityFoodandBrandLab,onaverage,dinersleave17percentof
theirmealsuneatenand55percentofedibleleftoversareleftatthe
restaurant.Thisispartlyduetothefactthatportionsizeshave
increasedsignificantlyoverthepast30years,oftenbeingtwoto
eighttimeslargerthanUSDAorFederalDrugAdministration(FDA)
standardservings.
Kitchencultureandstaffbehaviorsuchasover-preparationoffood,

3.DateLabelConfusion——Anestimated80percentofAmericans
prematurelydiscardfoodduetoconfusionoverthemeaningofdate
labels(e.g.,“sellby,”“bestifusedby,““expiresby,"and
soforth).Inreality,“sellby"and"useby“datesarenot
federallyregulatedandonlyserveasmanufacturersuggestionsfor

4.Overbuying一Salesonunusualproductsandpromotionsthat
encourageimpulseandbulkfoodpurchasesatretailstoresoften
leadconsumerstopurchaseitemsthatdonotfitintotheirregular

5.PoorPlanning一Withoutmealplansandshoppinglists,consumers
