Using a high-efficiency wood or pellet stove can be a cost-effective way to reduce your home heating costs compared to other fuels like natural gas, fuel oil, or electricity. According to Penn State Extension, the greatest savings are realized when you cut your own firewood rather than opting to buy pellets or have cordwood delivered. However, there are several hazards associated with use of a chainsaw or ax for felling trees or splitting firewood; the CDC estimates 36,000 people visit hospital emergency departments annually for injuries caused by chainsaws. If you plan to cut your own firewood this winter, it’s important to keep safety top of mind. [Read more…]

Produce Safety Rule Proposed Agricultural Water Revisions to Subpart E
Subpart E of the Food Safety Modernization Act Produce Safety Rule has been under review for some time. On December 6, 2021, FDA published in the Federal Register the proposed final rule. There is a 120-day comment period which ends April 5, 2022. Once the FDA reviews comments and publishes the final rule it will go into effect 60 days later. The proposed rule applies to anyone who produces fresh fruits or vegetables and sales over $25,000 annually.
Federal Register: https://www.federalregister.gov/documents/2021/12/06/2021-26127/standards-for-the-growing-harvesting-packing-and-holding-of-produce-for-human-consumption-relating. The proposed rule is 35 pages – 69120 to 69155 (small print). The actual proposed rule starts on page 69130.
The current agricultural water compliance dates are set to begin in January 2022, but
FDA intends to exercise enforcement discretion for the agricultural water requirements for covered produce (other than sprouts) while proposing to extend the compliance dates for ALL Subpart E provisions. More information about the proposed compliance dates will be announced in the Federal Register and we will publicize those dates when announced.
FDA is looking for comments that are thoughtful and substantive, containing real life examples and solutions will assist them in creating a document that better suits the needs of fresh produce farmers across the country.
The On-Farm Food Safety Team has started to review the proposed rule. We will be sending out more information with areas where you may want to comment in the next few weeks.

Bees, Wasps, And Hornets In The Agriculture Workplace

European Hornet Photo by Sal. Mangiafico
The website, Insect Identification.Org has a list of eighty seven Hymenoptera species found in New Jersey. Hymenoptera are ants, bees, wasps, and sawflies. It’s quite amazing that these species have been apart of the evolutionary record for more than 260 million years. Many are predatory species that feed on other insects. And not surprisingly at first glance, several insects have evolved camouflage to look like the stinging biting insects we learn to avoid. There are currently three theories to explain these body shapes and coloring choices. Mimicry, Masquerading, and what I would call ‘Mob Camouflage’ for lack of a better term as the authors of A Hypothesis to Explain Accuracy of Wasp Resemblances’ state.
Mimicry by less aggressive wasps and non-stinging insects like moths is known as Batesian mimicry and Müllerian mimicry. Batesian mimicry is a phenomenon observed by Sir Henry Walter Bates a British Naturalist who studied butterflies in the late 19th century. In Batesian mimicry, non-harmful species known as the mimic have evolved to model the appearance of a species whose potential predators have learned is harmful (venomous sting, biting injury, poisonous) and thus avoid consuming.
Müllerian mimicry is named after German naturalist Fritz Müller and involves two different but similar species purposefully mimicking each other’s appearances and bad taste to confuse predators.
A third hypothesis proposed in the 2016 paper ‘A Hypothesis to Explain Accuracy of Wasp Resemblances’ suggests that non-aggression by wasps towards sisters during hunting is innate and on sight and is a means to confuse or slip by the sight of the selecting agent (the bird) in a crowd.
A good example of these three adaptations on display in 2021 was the emergence of cicada broods and multiple grasshopper broods. These species are food for many Hymenoptera species and when food is abundant bee, wasp and hornet populations soar. This resulted in significant number of calls to extension offices for assistance in identifying similar patterned species. Many callers wanted to know if their hornet encounter was an asian giant hornet (Vespa mandarinia), a new introduction first found in the Pacific Northwest in 2019 that is not known to be present elsewhere in the U.S. at this time.
On another note, it remains to be seen if any of these common predatorory wasp and hornets develop a taste for spotted lanternflies. In their native range, the parasitic wasp Dryinus browni has developed a taste for lanternflies and biologists are studying the logistics of bringing this species to the U.S. The gypsy moth Ooencyrtus kuvanae introduced to the U.S. in 1908 has also been observed to prey on lanternflies.
Another surprising revelation about mimicry in wasp species, is that for some of these common North American species, both prey and predator can change their color banding from yellow and black to red and black as their range changes. Species commonly seen as yellow and black in New Jersey are red and black in Florida and most likely do so to maximize the benefits of mimicry, masquerade, and mob camouflage relative to the abundance of one particular color pattern over another in that ecological niche. As much of the work force in hand harvest agriculture migrates with the crop harvest, workers maybe familiar with the same species venomous sting but associate it with a different color pattern as seen in a different region or country.
Regardless of where in the world we are from, vertebrates like ourselves innately associate these color patterns with avoidance. In human societies, these warning stripes are incorporated into clothing and infrastructure as social cues to both protect the wearer (safety vests) and alert others to safety hazards.
General Body Color Pattens in Stinging and Non-Stinging Bees, Wasps, and Hornets
Green Body and Yellow: Three different types of sweat bees, cuckoo wasp
Red and Black: Red velvet wasp also known as ‘cow killer’ or as ‘red velvet ant’
Yellow and Black: Eastern yellow jacket hornet, southern yellow jacket hornet, common yellow jacket wasp, asian horntail, five-banded thynnid wasp, ichneumon wasp, hyperparasitic wasp, leucospid wasp, bumble bee, pigeon tremex, square head wasp, weevil wasp
Yellow and Brown: Cicada wasp, paper wasp, european hornets, long tailed ichneumon wasp
Black and White: White faced hornets, mason wasp, leaf cutter bee, potter wasp, scoliid wasp
Brown and Black: Great golden digger wasp, honey bee

Several companies have published wall posters available on the internet of common bees, wasps, and hornets that may be useful in the workplace. These visual aids would be a useful addition to worker bulletin boards in facilities processing the preferred sugar source (vegetable sugars) many of these species feed on throughout the summer.
Concerned about severe reactions to bee, wasp, ant, or hornet stings? Here is an informative article by Merk Manual https://www.merckmanuals.com/home/injuries-and-poisoning/bites-and-stings/bee,-wasp,-hornet,-and-ant-stings?redirectid=12.
The CDC has an employer fact sheet on how to reduce worker exposure to stinging members of the bee, wasp, and hornet families. https://www.cdc.gov/niosh/topics/insects/beeswasphornets.html.
Talk to your occupational health nurse about adding over the counter antihistamines like diphenhydramine, famotidine, and prescription epinephrine to your agriculture workforce first aid kit. Bee venom medical alert necklaces, bracelets and arm bands can be worn by hyper-sensitive workers in the workforce to aid in rapid response if someone is stung and unable to articulate they need medical attention.
Lastly, keep in mind that as climate changes, the seasons become longer, and temperatures are more favorable to yielding higher populations of queens and workers, the time frame to destroy nests when stinging flying insects are hybernating is also changing.
Stay Safe on the Road During the Harvest
Autumn is harvest season on the farm, and farmers are rushing to get the harvest in before the weather becomes cold. With harvest season getting underway, more heavy farm equipment is going to be out on the same roads as vehicle traffic, going from field to field, dramatically increasing the odds for accidents. During this season, it is important to be aware of the increased possibility of accidents and injury, especially when using farm machinery. One area to pay particular attention to is road safety while moving equipment. Here are some tips to help make sure the season is safe.

Make sure your farm vehicles and equipment are visible.
- Verify that all lights and flashers on your farm vehicle are working properly.
- Use warning flashers, flags, lights and slow-moving vehicle emblems on all equipment.
- Apply reflective tape to machines to improve visibility for motorists at dusk.
- Avoid traveling before dawn and after dusk if you can. If you need to drive during these times, ensure that your headlights are working. Headlights help you see and be seen.
- Consider the use of an escort vehicle following with lights and flashers
Also, make sure you know the size of all tractors, vehicles and equipment. Be mindful of the height of your farm equipment and avoid power lines, low bridges and other overhead obstacles. Remember to communicate with fellow motorists on the road. Use turn signals and hand signals whenever possible to communicate with fellow drivers. Avoid distractions and make safety a priority on the road. Also, particularly important is to pay attention to when you are feeling tired and fatigued. Taking a break to rest is an important safety tool not to be overlooked.
