How much of the food in your fridge will you toss before it reaches the table?
0
7211
4421
你雪櫃入面嘅食物有幾多 會喺送上飯枱之前就掉咗?
00:11
Hamburger buns from last summer’s picnic? Milk past its sell-by date?
1
11632
4547
喺舊年夏天野餐剩低嘅漢堡包? 過咗保質期嘅牛奶?
00:16
Carrots that lost their crunch?
2
16179
2460
定係已經唔爽脆嘅紅蘿蔔?
00:18
Countries around the world waste huge amounts of food every year,
3
18848
4922
每年,世界各地浪費大量食物
00:23
and the United States is one of the worst offenders.
4
23811
3462
而美國係其中一個 浪費最嚴重嘅國家
00:27
37% of US food waste comes from individual households.
5
27857
5672
美國食物浪費有三成七 嚟自個人家庭
00:33
And roughly 20% of those food items are tossed because consumers aren’t sure
6
33613
4880
其中約莫兩成嘅食物掉咗 係因為消費者唔清楚
00:38
how to interpret the dates they’re labeled with.
7
38493
2961
點樣理解食物標籤上嘅日期
00:41
But most of those groceries are still perfectly safe to eat.
8
41621
3795
但大部分嘅食物 其實依然可以安全食用
00:45
So if the dates on our food don’t tell us that something’s gone bad,
9
45583
4463
咁如果食物上嘅日期 唔係話俾我哋知啲嘢幾時壞咗
00:50
what do they tell us?
10
50046
1877
佢哋究竟表示啲乜?
00:52
Before the 20th century,
11
52256
1669
喺二十世紀之前
00:53
the path between where food was produced and where it was eaten
12
53925
3628
由製造食物 到食用地方之間嘅途徑
00:57
was much more direct,
13
57553
1627
嚟得直接得多
00:59
and most people knew how to assess freshness using sight, smell, and touch.
14
59388
5089
而大部分人識得憑外觀、氣味同觸感 去評估食物新唔新鮮
01:04
But when supermarkets began stocking processed foods,
15
64560
3754
但當超市開始積存加工食品後
01:08
product ages became harder to gauge.
16
68314
3045
究竟啲食物擺咗幾耐 就難以估計
01:11
In the US, grocers used packaging codes
17
71818
3128
喺美國,食品雜貨商採用包裝代碼
01:14
to track how long food had been on the shelves,
18
74946
2502
去追蹤住食物擺上貨架嘅時間
01:17
and in the 1970s, consumers demanded in on that info.
19
77448
4546
而喺 70 年代 消費者更要求得到呢啲資訊
01:22
Many supermarkets adopted a system still in place today called open dating,
20
82453
5339
好多超市至今仍然採用呢種 叫做「公開標註日期」嘅系統
01:27
where food manufacturers or retailers labeled products with dates
21
87959
3587
食品製造商或者零售商 須要喺食品上標示日期
01:31
indicating optimum freshness.
22
91546
2586
嚟顯示最佳新鮮程度
01:34
This vague metric had nothing to do with expiration dates or food safety.
23
94465
4880
呢個咁空泛嘅指標 同食品過期或者安全食用毫無關係
01:39
In fact, it’s rarely decided with any scientific backing,
24
99554
3753
事實上,呢種做法背後 都係冇乜科學根據
01:43
and there are usually no rules around what dates to use.
25
103307
3587
通常都冇規則訂明 應該用邊啲日子
01:47
So most manufacturers and retailers are motivated to set these dates early,
26
107061
5422
所以大部分食品製造商 同零售商都傾向攞個早啲日子
01:52
ensuring customers will taste their food at its best and come back for more.
27
112483
5214
確保顧客喺食物最新鮮嗰陣享用 下次會再返嚟幫襯
01:58
This means many foods are safe to eat far beyond their labeled dates.
28
118489
5798
即係話好多食品喺過咗標籤日期之後 都係可以安全食用
02:04
Old cookies, pasta, and other shelf-stable groceries might taste stale,
29
124787
5255
擺咗好耐嘅曲奇、意粉同其他耐儲存嘅食品 食落可能味道會唔新鮮
02:10
but they aren’t a health risk.
30
130042
1794
但佢哋唔會危害健康
02:12
Canned foods can stay safe for years,
31
132044
2628
罐頭食物可以擺好耐
02:14
so long as they don't show signs of bulging or rusting.
32
134672
3003
只要罐身冇凸起 或者生鏽就可以食用
02:18
Low freezer temperatures keep bacteria that cause food poisoning in check,
33
138050
4213
雪櫃低溫處理 可抑制食物產生中毒嘅細菌
02:22
preserving properly stored frozen dinners indefinitely.
34
142263
3795
冷凍係無限期妥善儲存晚餐嘅方法
02:26
Refrigerated eggs are good for up to five weeks,
35
146559
2919
雞蛋放喺雪櫃 可以儲存五個禮拜
02:29
and if they spoil, your nose will let you know.
36
149478
2628
如果啲雞蛋壞咗 你個鼻會聞得出
02:32
And you can always spot spoiled produce by off odors, slimy surfaces, and mold.
37
152273
6173
而你由異味、滑潺潺嘅表面同霉菌度 分辨到啲壞咗嘅農產品
02:38
Of course, there are some cases where you’re better safe than sorry.
38
158988
3837
當然,某啲情況 都係寧願掉咗佢好過冒險啦﹗
02:42
The USDA recommends eating or freezing meat within days of purchase.
39
162909
4546
美國農業部建議將買番嚟嘅肉類 喺幾日內食完或者急凍
02:47
Beyond their printed dates,
40
167496
1377
過咗期嘅
02:48
ready-to-eat salads, deli meats, and unpasteurized cheeses
41
168873
4171
即食沙律、熟食肉類 同冇經巴斯德式消毒嘅芝士
02:53
are more likely to carry pathogenic bacteria
42
173044
3128
係比較容易傳播致病嘅細菌
02:56
that can slip past a smell or taste test.
43
176172
2669
而你憑嗅覺同味覺 都察覺唔到
02:59
And the dates on infant formula are regulated to indicate safety.
44
179050
4421
至於嬰兒奶粉配方係受到規管 須要標示安全日期
03:03
But while some of these labels work as intended, the vast majority don’t.
45
183596
4796
雖然有啲標籤發揮到預期嘅作用 但係極大部分都冇做到
03:08
In a 2019 survey of over 1,000 Americans,
46
188601
3629
喺 2019 年嘅調查 訪問咗超過一千個美國人
03:12
more than 70% said they use date labels to decide if food is still edible,
47
192230
5755
多過七成人表示會以日期標籤 去判斷啲食物重食唔食得
03:17
and nearly 60% said they’d toss any food past those dates.
48
197985
4546
而接近六成人就表示會掉咗 任何過期嘅食物
餐廳同食品雜貨商 通常都會咁樣做
03:23
Restaurants and grocers often do the same.
49
203157
2836
03:26
To avoid all this waste, many experts advocate for laws
50
206661
3503
為要避免浪費食物 好多專家主張要立法
03:30
to require that date labels use one of two standardized phrases:
51
210164
4671
要求日期標籤 必須用兩種標準句語之一:
03:35
“Best if used by,” to indicate freshness, or “Use by” to indicate safety.
52
215419
5714
「此日期前最佳」表示新鮮度 「此日期或之前食用」表示食用安全期
03:41
This solution isn't perfect,
53
221300
1669
呢個解決方法並非完美
03:42
but some US researchers estimate that setting these standards at a federal level
54
222969
4421
但有啲美國研究員估計 喺聯邦層面制定呢啲標準
03:47
could prevent roughly 398,000 tons of food waste annually.
55
227390
5922
可以避免每年浪費 大約三十九萬八千噸嘅食物
03:53
Grocers could also try removing date labels on produce,
56
233896
3670
雜貨商亦可以嘗試 搣走喺農產品嘅食物標籤
03:57
as several UK supermarket chains have done
57
237566
2503
正如英國幾間連鎖超市咁做
04:00
to encourage consumers to use their own judgement.
58
240069
3003
鼓勵消費者靠自己做判斷
04:03
Many experts also advocate for policies incentivizing grocers and restaurants
59
243239
4588
好多專家亦提倡制訂政策 獎勵食品雜貨商同餐廳
04:07
to donate unsold food.
60
247827
2127
捐出賣唔出嘅食物
04:10
Currently, confusion around dates has led at least 20 US states
61
250371
4588
目前,對於保質期造成嘅疑惑 令美國至少有二十個州
04:14
to restrict donating food past its labeled date,
62
254959
3086
限制捐贈過咗標籤上保質期嘅食物
04:18
even though the federal government actually protects such donations.
63
258212
3796
其實,縱使聯邦政府 有保護呢種類型嘅捐贈
04:22
Countries like France go even further,
64
262174
2211
法國呢類國家更進取
04:24
requiring that many supermarkets donate unsold food.
65
264385
4379
要求多間超市捐贈賣唔出嘅食物
唔理政府點樣決定
04:29
Regardless of what your government decides,
66
269056
2336
04:31
the best way to prevent food waste is to eat what you buy!
67
271392
3587
防止浪費食物嘅最佳方法 係食曬買嚟嘅食物
04:35
And don’t forget that your eyes, nose, and tongue
68
275021
2877
唔好唔記得你對眼 鼻哥同埋條脷
04:37
are usually all you need to decide if food is fit for consumption
69
277898
4505
通常係用嚟決定 究竟啲食物係唔係重食得
04:42
or the compost bin.
70
282403
1418
定係掉落堆肥箱度
