Covid-19 and California Dairy Producers
By Dr. Michael Payne, UC Davis, School of Veterinary Medicine and Director, CDQAP
As California enters its sixth week of a state-wide Stay-at-Home Order, our steadfast producers and processors continue to harvest and ship essential dairy nutrition. While producers are meeting the challenges with their characteristic courage and ingenuity, it’s easy to become overwhelmed by the torrent of COVID-19 information flooding in from every outlet. The following provides some carefully selected information specifically for dairy farmers in California.
COVID-19 and Food Safety
Some dairy customers, neighbors and others may have questions. There is reassuring science explaining how typical dairy food safety precautions eliminate the virus. Iodine levels in teat-disinfectants, chlorine levels in CIP systems and of course pasteurization temperatures all inactivate the virus. These are just some of the reasons that the FDA, CDC and the European Food Safety Agency all say there is no evidence that COVID-19 virus is transmitted by food or food packaging. Additionally, it’s also useful for our customers to know that animal coronaviruses aren’t transferred between livestock and humans. Cattle cannot contract and transmit the COVID-19 virus to people any more than your dog could give you the K9 coronavirus that causes kennel cough.
The California Department of Food and Agriculture (CDFA) has unequivocally identified agriculture as part of the state’s critical infrastructure and that ag workers are exempt from work travel restrictions. The Department of Homeland security (DHS) similarly recognizes those producing, processing and delivering food as critical infrastructure workers with unique responsibilities and privileges. With the current Stay-at-Home Order, some farm and processor employees have expressed concern they could be stopped, questioned and even fined while traveling to and from work. Western United Dairies has provided a document explaining and documenting an employee’s status in a critical infrastructure industry. The template is available in both English and Spanish and can be kept in the employee’s vehicle.
All dairymen want to protect the health of their employees and themselves while working during this outbreak. Prevention starts with discussing COVID-19 with your employees, what it is and how they can keep themselves and their families safe. A useful tool to start those discussions is a one-page fact sheet for dairy employees, available from AITech in both English and Spanish.
The fact sheet’s familiar guidance (social distancing, hand washing and self-quarantine) can be reinforced with posters from the Centers for Disease Control, CDC, available for download in both English and Spanish. Cornell Cooperative Extension also developed an excellent guide on addressing coronavirus on farms.
Employee break rooms and bathrooms are potential areas for virus transfer. Keep restrooms stocked with disinfectants, soap and towels. Minimize congregation when possible and reasonable for your farm. When use of common areas is unavoidable, implement a regular disinfection program. For regular disinfection of surfaces commonly touched with ungloved hands, CDC has extensive guidance. Commonly available household bleach (1/3rd cup per one gallon water) will be effective when other approved disinfectants are in short supply or prohibitively expensive. Never mix bleach with other cleaning products, especially those containing ammonia, as it can release dangerous chlorine gas.
According to CDC guidance employees showing up for work with symptoms (especially fever, cough, or shortness of breath) should immediately be separated from other employees, customers, and visitors and sent home. According to the Equal Employment Opportunity Commission (EEOC) sending a sick employee home is not a violation of the Americans with Disabilities Act. A comprehensive review of California producer obligations for their employees during the epidemic was developed by Western United Dairies legal affairs team. The majority of COVID-19 patients will show only mild to moderate symptoms and can be cared for at home using CDC recommendations.

Inspections & Allied Industry
CDFA food safety inspections are an essential function in ensuring a safe food supply. While CDFA will continue their routine visits to dairy farms and processing plants, inspectors will be implementing best practices to protect themselves, producers and employees. Inspectors are following all industry standards including observance of biosecurity and hygienic practices, as well as wearing any protective gear a farm requires. These same precautions are similarly being implemented for inspections of meat processing plants and slaughter facilities. CDFA also recognizes rendering as an essential service vital to public health and safety and has provided supporting documentation for the industry.
Auction markets are also considered part of agriculture’s critical infrastructure and are typically staying open for business. Individual auctions however may implement a variety of protective strategies ranging from altering café service, limiting the number of buyers or having consignors deliver livestock and return home rather than remaining at the facility. Producers with market cows should contact their auction yard beforehand for specific changes.
Although no producers we know of are anticipating milk pick-ups being halted, some dairy processors are beginning to develop contingency plans in the event that a plant’s production needs to be slowed or stopped. Such circumstances might include labor shortages, decreased demand from restaurants and schools, loss of international markets, etc. In the event that milk is stranded and requires on-farm disposal the Central Valley Regional Water Board has provided guidance.
A number of organizations and agencies have developed coronavirus webpages. Perhaps the most exhaustive dairy-related page is from the National Milk Producers Federation. For producers looking for just the highlights, NMPF’s coronavirus handbook is only three pages long but dense with information. Pennsylvania’s Center for Dairy Excellence is another frequently updated site. Closer to home, in the interest of public safety, UC Agriculture & Natural Resources (ANR) meetings have been canceled, postponed or converted to on-line through April 30. UC Cooperative Extension and your farm advisors are still available by email or phone.
The California Dairy Research Foundation is still generating critical information for producers and answering phones and emails. Producers with COVID-19 questions for UCD or CDQAP are encouraged to contact Dr. Michael Payne at
