Basil is one of the most popular and commonly used herbs in many cuisines around the world. Its sweet peppery flavor adds a distinctive taste to dishes like pesto tomato sauces, and various Mediterranean recipes. However, basil leaves are also prone to damage from pests like insects, slugs, and snails. So what should you do if you spot holes in your basil leaves? Can you still use them for cooking or should you throw them out? Let’s settle this debate once and for all.
What Causes Holes In Basil Leaves?
Before deciding whether to eat or discard pest-damaged basil, it helps to understand what causes the holes in the first place. Here are some of the most likely culprits
-
Slugs and snails – These slimy mollusks feed on basil leaves during the night, leaving behind telltale irregular holes surrounded by slime residue. They thrive in damp, mulched areas.
-
Insects – Insects like Japanese beetles, earwigs, caterpillars, and leafminers tunnel into leaves, causing small holes and serrated edges on basil foliage. Aphids and other sap-sucking insects can cause curled, yellowing leaves with holes.
-
Environmental factors – Wind damage, hail, heavy rain, and some fungal diseases can also put tiny holes in basil leaves.
So in most cases, the holes come from pests like slugs and insects eating the leaves as a food source. But is the basil still safe to eat if it has this type of damage?
Is It Safe To Eat Basil With Holes?
The good news is that minor cosmetic damage from pests does not make basil unsafe to eat. As long as the pest damage is limited to small holes and there is no widespread rot or wilting, the basil leaves can still be consumed.
Here are a few key points on the safety of holey basil:
-
Pest damage is superficial – Slugs, insects, wind, and hail only affect the surface of the leaf. They do not introduce any harmful toxins or bacteria.
-
Wash thoroughly before use – Rinsing basil under running water helps remove any pest residue, frass (bug poop), or slime left behind.
-
Remove severely damaged leaves – While small holes are fine, discard any leaves that are excessively chewed up or rotting. This prevents using moldy leaves.
-
OK for cooking – Heat from cooking destroys potential bacteria and denatures any proteins from pests.
-
Eat quickly – Use damaged basil within a day or two before the holes can expand and cause decay.
So go ahead and use those holey basil leaves to make your favorite recipes! The minor cosmetic flaws do not make the basil unsafe or lessen its flavor. Just be sure to wash it thoroughly first and remove any severely damaged leaves.
Tips To Prevent Holes In Basil Leaves
While it’s fine to eat basil with minor holes, preventing pest damage in the first place helps your plant look nicer and last longer. Here are some tips to stop the holes from forming:
-
Remove garden debris and weeds where slugs and snails hide.
-
Apply diatomaceous earth or copper tape to deter slugs/snails.
-
Use row covers to keep insect pests off plants.
-
Spray neem oil or insecticidal soap to kill small insect pests.
-
Apply beneficial nematodes to soil to kill soil-dwelling pests.
-
Use pheromone traps and hand pick large pests like beetles.
-
Water carefully to prevent fungal diseases that can cause holes.
-
Provide wind barriers and shade protection to minimize physical leaf damage.
With vigilance and integrated pest management, you can prevent most of the damage and keep your basil looking fresh and hole-free. But even if some pesky bugs sneak through, rest assured that basil with minor holes is perfectly fine to eat as long as you wash it first. So consume and enjoy your homegrown basil without worry!
Frequently Asked Questions About Eating Basil With Holes
Here are answers to some common questions about pest damaged basil leaves:
Can you still use basil leaves if they have holes?
Yes, as long as the holes are small and superficial, you can still use basil leaves in cooking and eating. Rinse thoroughly to remove any residue from pests.
Should I cut around the holes in basil leaves?
That’s not necessary. The holes do not contaminate the rest of the leaf, so you don’t need to cut around them. Just use the intact parts of the leaf as usual.
Will holes in basil leaves make my food unsafe?
No. The minor cosmetic damage does not introduce any harmful bacteria or toxins. Cooking temperatures will kill any potential germs from pests.
Can I use basil with holes for pesto?
Absolutely. Minor holes will not affect the flavor or texture of pesto. The blending will incorporate the whole leaf evenly.
Do holes make basil go bad faster?
Slightly. Severely damaged leaves with expanding holes can decay faster. Use holey leaves within 1-2 days for best quality and flavor.
Should I discard my whole basil plant if it has some holes?
No, there’s no need to throw out the whole plant. Just remove severely damaged leaves. The rest of the plant is still usable.
Will wash fix holey basil leaves?
Washing is important to rinse away pest residue, but it won’t make the holes disappear. Washing just makes sure you remove any remaining pests or slime.
Can you eat around the holes in a basil leaf?
You can, but it’s unnecessary. The holes do not contaminate the rest of the leaf, so there’s no need to eat around them.
When to Avoid Greens That Have Holes
If you are particularly unlucky, it is possible to become gravely ill from eating damaged greens.
In your vegetable beds, check the ground nearby to look for signs that a mammal may have been nibbling on the leaves.
If you find piles of deer or rabbit poop in the vicinity, do not eat the greens.
These animals can spread dangerous strains of E. coli (the “lab rat” of bacteria and a common ingredient in feces), as well as Salmonella.
While most strains of E. coli are harmless, there are strains that produce a toxin that can prove fatal to susceptible individuals like young children and the elderly.
Deer can be carriers of these strains. The toxin that these bacteria produce can be inactivated by heating food to 158°F, but why take a chance?
I think it’s far better to forego part of your crop than it is to risk your health.
Cat droppings can also pose a health hazard. They can spread the parasite that causes toxoplasmosis.
While toxoplasmosis infections often pass without causing any symptoms, they can cause serious problems for pregnant women, and have been found to cause mental illness in some cases.
Some gardeners report using soiled sheep bedding in the garden to keep the cats away, but that will not be practical for most people.
However, the principle should work for other types of animal bedding that contain urine, so if you keep farm animals on your land, you are in luck!
Beyond the realm of mammals, lizards kept as pets commonly spread Salmonella, though it is not clear whether wild lizards are a threat in the veggie patch.
However, according to Anna Rovid Spickler, veterinary specialist from the Center for Food Security and Public Health, “all reptiles can be sources.” It may behoove you to err on the side of caution if you find lizards in your garden as well.
Are Greens with Holes in Them Safe to Eat?
If you pick the leafy vegetables that you so lovingly tended through the season, and you discover that something – or someone – has been enjoying their own feast before you had a chance to harvest your crops, are they safe to consume?
Fortunately, there’s good news!
Greens with holes in them that were created by feeding insects or slugs should be fine to eat, if you cut away the damaged parts.
However, there are times when you do want to avoid produce that has been damaged by the local wildlife. Let’s take a look.
