A viral video from 2018 showed a woman peeling what appeared to be a thin plastic film from romaine lettuce. The video sparked concern among consumers, especially in light of an E. coli outbreak linked to romaine lettuce that resulted in at least 80 infections and over 40 hospitalizations. However, experts have confirmed that the substance in the video is not plastic but rather the lettuce's natural response to cold temperatures, known as epidermal peeling or epidermal blistering. This phenomenon occurs when freezing weather conditions cause blistering in romaine and other types of lettuce, resulting in a thin protective layer that can be peeled off. While it may look similar to plastic, this natural coating is safe and not harmful in any way.

What You'll Learn
The plastic is a natural substance, not a coating
There have been several viral videos showing people peeling a plastic-like film off romaine lettuce leaves. These videos have sparked concerns about the toxicity of store-bought lettuce. However, the substance being peeled off the lettuce leaves is not plastic. It is a natural phenomenon known as epidermal peeling or epidermal blistering. This occurs when romaine lettuce is exposed to freezing temperatures during the growing process, causing the leaves to form a protective layer that can be peeled off.
The confusion arises because the film resembles plastic and can be peeled off the lettuce leaves. However, it is important to understand that this film is not artificial or externally applied to the lettuce. It is a natural response of the lettuce to cold temperatures, much like how human skin gets frostbite or a sunburn. The lettuce's outer skin experiences a type of "freeze burn", resulting in blistering that can then be peeled away.
While the exact cause of this phenomenon is still being studied, it is generally agreed that temperature plays a significant role. Rapid temperature changes, particularly cold temperatures at night, can cause this protective layer to form on the lettuce leaves. This natural occurrence has been observed by lettuce growers and agricultural experts, who confirm that it is unrelated to contamination or E. coli outbreaks associated with romaine lettuce.
Although it may be unsettling to see this plastic-like film on lettuce, it is important to remember that it is a natural occurrence and not harmful. The lettuce is still safe to consume, and the peeling of the epidermal layer does not indicate any toxicity or contamination. This response is the lettuce's way of protecting itself from extreme temperatures, and it poses no risk to consumers.
It is worth noting that some people speculate about the presence of pesticides or other agronomic conditions that could contribute to the toughness or texture of the lettuce leaves. However, these speculations are just theories, and there is no conclusive evidence to support them. The general consensus among experts is that the plastic-like film on romaine lettuce is a natural substance and not an artificial coating.

It's caused by extreme temperature changes
There have been several viral videos and online claims that romaine lettuce is covered in a thin layer of plastic. These claims are false. The substance in question is not plastic, but rather the result of a natural process called epidermal blistering or peeling, which occurs when lettuce is exposed to cold temperatures during the growing process.
Lettuce grown in regions with cold nights, such as Arizona, can develop this translucent film on its leaves. This film is the lettuce's response to the cold, similar to how human skin gets frostbite or a sunburn. The extreme temperature changes cause the outer skin of the lettuce to experience a type of freeze burn, resulting in blistering. This blistering forms a thin protective layer on the leaves that can be peeled off.
The phenomenon of epidermal peeling has been well-documented by agricultural experts and is not harmful or dangerous in any way. It is purely a natural reaction of the lettuce to protect itself from the cold. While it may be aesthetically unappealing to some, it is safe for consumption.
The confusion and concern around this issue may have been exacerbated by the timing of the videos, which circulated during a nationwide E. coli outbreak affecting romaine lettuce. However, the two issues are unrelated. The epidermal peeling is not a sign of contamination or any external application, but rather an internal response of the lettuce to extreme temperature changes.
It is important to verify information before spreading it, especially when it comes to food safety. While it is understandable that consumers may be cautious, relying on trusted sources and fact-checking websites can help dispel misinformation and prevent unnecessary panic.

It's known as epidermal peeling or blistering
Several viral videos have surfaced over the years, showing people peeling a plastic-like film off romaine lettuce leaves. These videos have sparked concerns about the toxicity of store-bought lettuce and its potential contamination with E. coli. However, the claim that romaine lettuce is covered in plastic is false. The substance being peeled off in the videos is not plastic, but rather a natural phenomenon known as epidermal peeling or blistering.
Epidermal peeling occurs when romaine lettuce is exposed to freezing temperatures during the growing process or storage. This phenomenon is similar to human skin experiencing a burn. The extreme cold causes the outer skin of the lettuce to form a type of "freeze burn", resulting in blistering. This blistering creates a thin, protective layer on the leaves that can be peeled off. While it may look like plastic, this coating is entirely natural and harmless.
The agricultural world is familiar with epidermal peeling, and it is not unique to romaine lettuce. Other types of lettuce and leafy vegetables, such as bok choy, can also exhibit this phenomenon when exposed to cold temperatures. The occurrence of epidermal peeling depends on the growing conditions and can be more prevalent in certain regions. For example, a significant amount of romaine lettuce is grown in Arizona, which experiences cold nights with sub-freezing temperatures.
While epidermal peeling is natural and harmless, it can be undesirable for consumers. The peeling makes it difficult to harvest and process the lettuce, and some people may find it unappealing to peel off the layer before consuming the lettuce. However, it is important to note that this natural protective layer is not a cause for concern and does not indicate contamination or toxicity.
Although the plastic-like coating on romaine lettuce is not actually plastic, it is worth mentioning that some fresh-cut vegetables and fruits can be treated with edible coatings to extend their shelf life. These coatings can be made from waxy liquids, edible oils, or other substances that create a protective barrier, similar to how plastic containers or films are used to preserve other types of food products. However, these edible coatings are typically applied to the entire vegetable or fruit and are not easily peelable like the natural epidermal layer of romaine lettuce.

It's not harmful or dangerous
There have been several viral videos circulating online that show people peeling what appears to be a plastic film off romaine lettuce leaves. These videos have sparked concerns about the safety of consuming such lettuce. However, it is important to clarify that the substance in question is not plastic, and it is not harmful or dangerous.
The substance observed in the videos is actually the natural "epidermal or skin layer" of the lettuce, known as epidermal peeling or blistering. This phenomenon occurs when romaine lettuce is exposed to cold temperatures during the growing process or transportation, resulting in a type of "freeze burn" on the outer skin of the lettuce. The freezing weather conditions cause blistering, leading to the formation of a thin protective layer on the leaves that can be peeled off.
While the appearance of this film may be off-putting to some, it is a completely natural phenomenon and is not harmful in any way. It is important to distinguish between this natural phenomenon and any potential contamination issues, such as the E. coli outbreaks associated with romaine lettuce in recent years. The peeling of the lettuce's skin is unrelated to any bacterial contamination and does not indicate that the lettuce is contaminated or unsafe for consumption.
The confusion surrounding the plastic-like substance on lettuce leaves can be attributed to the visual similarity of the epidermal layer to plastic. However, experts from the Department of Agriculture and lettuce growers have confirmed that it is not plastic. The lettuce's response to cold temperatures results in the formation of this translucent film, similar to how human skin gets a sunburn or frostbite. Therefore, consumers can be assured that the substance is not artificial or harmful and is a natural part of the lettuce itself.

It's not linked to contamination or E. coli
In 2018, a video went viral showing a woman peeling what appeared to be a thin plastic film from romaine lettuce. This video circulated at the same time as a nationwide E. coli outbreak affecting romaine lettuce, causing concern that the plastic film was linked to the contamination. However, this is not the case. The "plastic coating" is actually a natural phenomenon known as epidermal peeling, which occurs when lettuce is grown or stored in cold temperatures.
Epidermal peeling, or the blistering of the outer skin of lettuce, is a completely natural occurrence that has nothing to do with contamination or E. coli. It happens when lettuce is exposed to freezing temperatures, causing the leaves to form a protective layer that can be peeled off. While this may be off-putting to some consumers, it is important to know that it is safe and not linked to any food safety issues.
The woman in the video appears to be experiencing an extreme case of epidermal peeling, which can make it difficult for the lettuce to be harvested and processed. While this may have contributed to the video's virality, it is important to clarify that the peeling is not a sign of contamination. The E. coli outbreak affecting romaine lettuce at the time of the video was caused by the consumption of contaminated lettuce, as confirmed by investigations conducted by the FDA, CDC, and state partners.
It is worth noting that food safety problems related to leafy greens, including romaine lettuce, are a longstanding issue. Investigations have identified various factors that contribute to contamination, such as the presence of E. coli in water reservoirs and the intestinal tracts of animals. However, the natural phenomenon of epidermal peeling on lettuce leaves is not one of these factors and should not be cause for concern.
In summary, while the viral video of a woman peeling a plastic-like substance from romaine lettuce may have caused concern, the substance is not plastic and is not linked to contamination or E. coli. It is simply the natural result of growing or storing lettuce in cold temperatures, and consumers can be assured that it does not indicate any food safety risks.
