Is it OK to eat moldy strawberries? – If you find white fluffy stuff on your berries that looks a bit like cotton candy, that is mold. Mold is a fungus with spores that feed on the berries and grow thin threads that can look like fluff or cotton. This particular type of mold is common among fruits and is known as Botrytis fruit rot or gray mold,
- While moldy strawberries are unlikely to harm you, they can make you sick if you are allergic to molds in general, according to the USDA,
- And since berries are a soft-fleshed food, unlike apples or pears, it is not safe to simply cut away the moldy part, since the spores have likely gone into the flesh of the berry.
If a berry is bruised, but does not show any signs of mold, the bruised part can be trimmed away. A moldy strawberry should be thrown out. If you happen to accidentally eat a moldy strawberry, you’ll know it because, usually, moldy strawberries will have an off flavor that is a bit sour and acidic and may remind you of blue cheese.
- The off taste is nature’s red flag that your red berries are bad, if you missed the visual mold.
- A small amount of this mold is unlikely to make you sick.
- If you ate a larger amount, you might have some signs of gastric distress similar to mild food poisoning, but it should resolve on its own, and is not toxic or especially dangerous, just uncomfortable.

How do you know if strawberries are moldy?
Signs of Rot in Strawberries – Look for these signs to see if your strawberries have gone bad.
- Mold – older strawberries may develop white, dark brown, or black mold. The mold may be furry or look wet. It can be on the red part of the berry or the leaves.
- Soft Spots – rotten strawberries may have mushy spots. The mushy spots may be a slightly darker red or brown.
- Discolored Leave s – if the leaves at the top of the strawberry are turning yellow, are crinkly and brown, or have mold on them, they may be too old to eat. Yellowing or browning leaves are a sign the strawberries are past their prime.
- Smell – if the strawberries have a strong smell that’s acrid or ammonia-like, they are past their prime and shouldn’t be eaten. They won’t taste good and they may make you sick.
What does a bad strawberry look like?
Most strawberries look okay to eat—they may have a little bruise or a few spots, but they taste fine. If you’ve seen a bruised strawberry or one with spots, you may wonder if it’s still okay to eat? In some cases, it’s difficult to tell if strawberries are rotten or not. So how do you tell if strawberries are bad? To tell if strawberries are bad, you’ll need to inspect them. Strawberries that are bad may have white fuzz, brown spots and may be mushy. They may also taste off and have an alcoholic smell. If you see fruit flies and other bugs feasting on your strawberries, they may be going bad.

What is the common mold on strawberries?
Botrytis Fruit Rot The fungus that causes Botrytis fruit rot, also known as gray mold, is widespread in the environment. It can infect strawberry when spores landing on them and are exposed to free water during cool weather. Infections can either cause flowers to rot or Botrytis can become dormant in floral tissues.
- Dormant infections resume activity on the berry later in the season anytime before or after harvest when sugars increase and conditions become favorable to disease development.
- Infections first appear as small, often under the calyx.
- Lesions begin to sporulate within a day after resumption of growth, and sporulation appears under the calyx as a gray velvety mold.
Lesion size increases rapidly. Both green and red berries are susceptible. Infected berries maintain their original shape and take on a velvety, of spores. Initially, rotted areas are soft and mushy, becoming leathery and dry in the absence of high humidity.
Millions of spores are produced on each berry and become airborne at the slightest touch or breeze. Direct infection of the berries also occurs if berries are exposed to free water. These infections develop in the same manner as flower-infected berries but differ in that multiple initial lesions may appear anywhere on the berry’s surface.
During the growing season, the fungus is constantly present and is often found in new plantings. Nothing can be done to escape the presence of this fungus, but the level of inoculum in a particular field can be reduced by removing dead leaves and infected fruit.
- After harvest, the fungus survives in the soil as small, black, inactive sclerotia on tilled-in leaves and fruit.
- In addition, the fungus lives on decomposing, dead organic matter of many plant species in and around the growing area.
- Because wet, cool weather is necessary for development of this disease, it is mostly limited to the coastal growing regions and northern nurseries and causes very little damage in inland growing regions except during periods of unusually wet weather during fruit production.
Presently, control of Botrytis fruit rot ranges from repetitive fungicide treatments with no cultural control to intensive cultural methods with no fungicide applications. Environmental conditions in various microclimates play an important role in determining control strategies.
- Planting in areas where wind can rapidly dry out the plants and interrupt disease progress helps to reduce disease incidence.
- Remove and destroy dead or infected plant material to help reduce the amount of inoculum capable of producing new infections.
- Also, remove all ripe fruit during harvest as well as any fruit with signs of decay or rain damage.
Growing strawberries in plastic tunnels has proven to effectively reduce the incidence of Botrytis infections. Using plastic mulches to prevent berry-soil contact also reduces disease except where water puddles under the fruit on the plastic. Some cultivars have flowers and fruit that develop with an upright stature, which allows fruit to be exposed to better air movement and sunlight, and this reduces the risk of infection, but fruit tend to be more exposed to rain and hail.
Select fields that are isolated from conventional growing areas and have environmental conditions that are not conducive to disease development (i.e., warm, dry spring weather or areas where wind is prevalent at some point during the day). Use varieties that are suited to the growing area with necked fruit or reflexed calyx. Remove all fruit after spring and summer rains and all plant residue after harvest, as sanitation is crucial for good control.
There are several organic fungicides available, but none have shown consistent efficacy against gray mold. In areas without heavy coastal summer fog, inoculum levels may be low enough in clean fields that early sprays in spring can be omitted. In dry areas, leaf wetness seldom is of sufficient duration to cause epidemics, and some growers are finding it possible to grow strawberries without fungicides when strict sanitation practices are adhered to.
- In dense fog areas, inoculum density and environmental conditions conducive to disease development (i.e., cool, wet weather) should always determine when to apply fungicides.
- Because these conditions are usually seasonal, use a protective fungicide to prevent germination of spores when weather forecasts predict conditions ideal for disease development.
Thereafter, set spray schedules according to disease pressure and environmental conditions. No fungicide is recommended when conditions are not determined to be suitable for infection.

How Should You Handle Food with Mold on It? – Buying small amounts and using food quickly can help prevent mold growth. But when you see moldy food:
Don’t sniff the moldy item. This can cause respiratory trouble. If food is covered with mold, discard it. Put it into a small paper bag or wrap it in plastic and dispose in a covered trash can that children and animals can’t get into. Clean the refrigerator or pantry at the spot where the food was stored. Check nearby items the moldy food might have touched. Mold spreads quickly in fruits and vegetables.
FOOD | HANDLING | REASON |
---|---|---|
Luncheon meats, bacon, or hot dogs | Discard | Foods with high moisture content can be contaminated below the surface. Moldy foods may also have bacteria growing along with the mold. |
Hard salami and dry-cured country hams | Use. Scrub mold off surface. | It is normal for these shelf-stable products to have surface mold. |
Cooked leftover meat and poultry | Discard | Foods with high moisture content can be contaminated below the surface. Moldy foods may also have bacteria growing along with the mold. |
Cooked casseroles | Discard | Foods with high moisture content can be contaminated below the surface. Moldy foods may also have bacteria growing along with the mold. |
Cooked grain and pasta | Discard | Foods with high moisture content can be contaminated below the surface. Moldy foods may also have bacteria growing along with the mold. |
Hard cheese (not cheese where mold is part of the processing) | Use. Cut off at least 1 inch around and below the mold spot (keep the knife out of the mold itself so it will not cross-contaminate other parts of the cheese). After trimming off the mold, re-cover the cheese in fresh wrap. | Mold generally cannot penetrate deep into the product. |
Cheese made with mold (such as Roquefort, blue, Gorgonzola, Stilton, Brie, Camembert) | Discard soft cheeses such as Brie and Camembert if they contain molds that are not a part of the manufacturing process. If surface mold is on hard cheeses such as Gorgonzola and Stilton, cut off mold at least 1 inch around and below the mold spot and handle like hard cheese (above). | Molds that are not a part of the manufacturing process can be dangerous. |
Soft cheese (such as cottage, cream cheese, Neufchatel, chevre, Bel Paese, etc.) Crumbled, shredded, and sliced cheeses (all types) | Discard | Foods with high moisture content can be contaminated below the surface. Shredded, sliced, or crumbled cheese can be contaminated by the cutting instrument. Moldy soft cheese can also have bacteria growing along with the mold. |
Yogurt and sour cream | Discard | Foods with high moisture content can be contaminated below the surface. Moldy foods may also have bacteria growing along with the mold. |
Jams and jellies | Discard | The mold could be producing a mycotoxin. Microbiologists recommend against scooping out the mold and using the remaining condiment. |
Fruits and vegetables, FIRM (such as cabbage, bell peppers, carrots, etc.) | Use. Cut off at least 1 inch around and below the mold spot (keep the knife out of the mold itself so it will not cross-contaminate other parts of the produce). | Small mold spots can be cut off FIRM fruits and vegetables with low moisture content. It’s difficult for mold to penetrate dense foods. |
Fruits and vegetables, SOFT (such as cucumbers, peaches, tomatoes, etc.) | Discard | SOFT fruits and vegetables with high moisture content can be contaminated below the surface. |
Bread and baked goods | Discard | Porous foods can be contaminated below the surface. |
Peanut butter, legumes and nuts | Discard | Foods processed without preservatives are at high risk for mold. |
How long does it take for strawberries to mold?
How Fast Do Strawberries Get Moldy? – Fresh strawberries can go moldy very fast.
If strawberries are not refrigerated, they can last one to two days before growing mold. If stored in the refrigerator, they can last between five to seven days before going bad.
Strawberries can also be frozen for long-term storage. They will, however, lose their consistency – but you can still use them as puree.
What happens if you accidentally eat moldy fruit?
Some foods are meant to be moldy — and it’s safe to eat them. For example, blue cheese’s taste and appearance come from a mold related to the strain used to make penicillin, Mushrooms are fungi, which is also technically a mold. Cleveland Clinic is a non-profit academic medical center.

What happens if you accidentally eat moldy food? First, don’t panic — you’ll probably be okay.
“Be mindful of the fact that you ate it,” says dietitian Lillian Craggs-Dino, DHA, RDN, LDN, “And make sure you don’t have any symptoms for the rest of that day. Most likely, you’ll be okay.” However, in certain cases, the mold found on spoiled food could be dangerous, so if you suddenly develop symptoms such as shortness of breath, nausea, an elevated temperature or diarrhea, you should immediately seek medical help.
