Always be mindful of the time when food is outside a refrigerator or freezer. Typically, it should be no longer than two hours, and just one hour in the summertime, according to UC Cooperative Extension UC CalFresh nutrition program coordinator Elizabeth Lopez in an appearance on the Valley Pubic Television program Valley's Gold. (The food safety segment begins at the 18:30 mark.)
Lopez recommends using an insulated grocery bag with a frozen ice pack for the trip home from the store, and refrigerating leftovers in sealed containers soon after finishing a meal to maintain food safety.
The UC Cooperative Extension nutrition educator also provided cooking tips with program host Ryan Jacobson, the director of the Fresno County Farm Bureau. Lopez noted:
- Before beginning, wash hands with warm water and soap for 20 seconds.
- Make sure the food preparation area is clean.
- Designate certain cutting boards for fruit and vegetables, and others for meat and poultry.
- Wash fruit and vegetables under cool running water. No detergent is needed. Read the labels on pre-bagged produce. Some are ready to use, some need to be washed.
- Use a meat thermometer. Cook beef, pork and lamb to an internal temperature of 145 degrees F. Ground meats should be cooked to 160 degrees F. Poultry, whole or ground, should be cooked to 165 degrees F.
For more information, Lopez suggested consumers consult the USDA's Food Safety.gov website or Food Keeper app, available free in the app store.
Advice for the Home Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County
Response from the MGCC's Help Desk: Thank you for contacting the UC Master Gardener Program Help Desk with your request for weed identification. We really appreciate the picture that you sent along too. It was very helpful.
From your picture, this appears to be a weedy mallow. There are two types of weedy mallow that are common in California, the common mallow (Malva neglecta) and little mallow (Malva parviflora). Both of these mallows are also known as cheeseweed.
Malva (mallow) species look very similar. Neglecta and parviflora can only be distinguished by comparing the flower petals and fruit shape. Flowers bloom nearly year-round. They are small, white to pale pink and about 2/5 of an inch in diameter. Flower clusters are found at the bases of leaf stalks. Neglecta petals are longer than parviflora petals and the fruit of neglecta are smooth while those of parviflora are wrinkled. The fruit for both is sometimes described as looking like a tiny wheel of cheese with wedge-shaped sections therefore giving them the common name of cheeseweed. Each wedge of the fruit contains one reddish brown kidney shaped seed.
These annuals begin growing from seed with the first rains in the fall and quickly develop a deep taproot that becomes woody and makes the plant difficult to remove by hand or even with tools (as you have found). Left alone, these plants will spread and can grow between 2 to 5 ft. tall.
- Mallows are best controlled mechanically by hoeing or pulling out young plants.
- Young mallow can also be killed by cutting them off at the crown but older plants may re-sprout from the crown.
- Solarization is not effective for mallow control nor is flaming.
- Insects do feed on mallows but there are none that are specialized for control of these weeds.
- There are no chemical controls available for home use that are effective for controlling mallows. Mallow is one of the few weeds that glyphosate (“RoundUp”) is ineffective in controlling.
- Cultural control can be done by planting competitive desirable plants in areas where mallow is a problem. The shade provided by these plants will reduce germination and growth of mallow seedlings.
- Mulches can also be effective. At least 3 inches of organic mulch, such as bark or wood chips, will make it difficult for the seedling to emerge and will screen out the amount of light that mallow requires to effectively sprout. It is important to maintain the needed depth otherwise, the seedlings can push through and become established again.
I hope this information is helpful to you. Please let us know if you have any questions.

With all the increasing--and alarming--global concern about declining pollinators, it's great to see some good news:...
