The state has ordered a recall of raw goat milk sold from a dairy farm west of Modesto.
Routing sampling found campylobacter jejuni bacteria, but no illnesses have been reported, the California Department of Food and Agriculture announced Monday.
The product came from Valley Milk Simply Bottled, a small operation along Maze Boulevard west of Hart Road. The same farm has had two recalls of cow milk because of the same bacteria since 2019, again with no illnesses reported.
In recent weeks, the number of people who have contracted campylobacter infection has been higher than in previous weeks. The increase has been seen throughout the country and in all age groups. The period has been preceded by an increased proportion of broiler flocks carried on campylobacter (Swedish Veterinary Institute (SVA). Previous studies have shown that cases of disease are often linked to raw chicken meat, which makes it likely that increased prevalence of campylobacter in chicken flocks is the cause. In the next few weeks, the Swedish Public Health Agency will collect samples from the disease cases for analysis and typing as part of the microbiological monitoring program in order to identify the presence of common sources of infection.

Contamination of meats and meat products with foodborne pathogenic bacteria raises serious safety issues in the food industry. The antibacterial activities of phosphorous-fluorine co-doped TiO2 nanoparticles (PF-TiO2) were investigated against seven foodborne pathogenic bacteria: Campylobacter jejuni, Salmonella Typhimurium, Enterohaemorrhagic E. coli, Yersinia enterocolitica, Shewanella putrefaciens, Listeria monocytogenes and Staphylococcus aureus. PF-TiO2 NPs were synthesized hydrothermally at 250 °C for 1, 3, 6 or 12 h, and then tested at three different concentrations (500 μg/mL, 100 μg/mL, 20 μg/mL) for the inactivation of foodborne bacteria under UVA irradiation, daylight exposure or dark conditions. The antibacterial efficacies were compared after 30 min of exposure to light. Distinct differences in the antibacterial activities of the PF-TiO2 NPs, and the susceptibilities of tested foodborne pathogenic bacterium species were found. PF-TiO2/3 h and PF-TiO2/6 h showed the highest antibacterial activity by decreasing the living bacterial cell number from ~106 by ~5 log (L. monocytogenes), ~4 log (EHEC), ~3 log (Y. enterolcolitca, S. putrefaciens) and ~2.5 log (S. aureus), along with complete eradication of C. jejuni and S. Typhimurium. Efficacy of PF-TiO2/1 h and PF-TiO2/12 h NPs was lower, typically causing a ~2–4 log decrease in colony forming units depending on the tested bacterium while the effect of PF-TiO2/0 h was comparable to P25 TiO2, a commercial TiO2 with high photocatalytic activity. Our results show that PF-co-doping of TiO2 NPs enhanced the antibacterial action against foodborne pathogenic bacteria and are potential candidates for use in the food industry as active surface components, potentially contributing to the production of meats that are safe for consumption.

The Food Standards Agency has today published a study to further determine the principal sources of this foodborne disease.
A report published by the FSA confirms that chickens are the source of the majority of human cases of Campylobacter, followed by other animals such as sheep, pigs and cows. This infection may have been passed to people directly through food, but could also be via environmental and water contamination.
The Campylobacter Source Attribution Study, launched in 2015 as part of the FSA’s wider and ongoing Campylobacter Reduction Programme, also reveals an increase in antimicrobial resistance within Campylobacter strains between 1997 and 2018. Work is continuing in this area to determine the full impact.
FSA Head of science, evidence and research, Rick Mumford, said:
“We will use these findings to better understand the causes of Campylobacter infection, and to inform further work on foodborne transmission. This will also help to identify further research areas to explore as we seek to reduce the overall burden of Campylobacter infection in the UK.”
Around 300,000 human cases of Campylobacter are estimated to be acquired from food each year in the UK, out of a total of around 630,000 cases. Campylobacter lives in the intestinal tracts of a wide range of mammals, birds and even insects.
Researchers embarked on this project to determine the key reservoirs of human Campylobacter infections and help identify potentially effective risk management strategies. The project assessed patient samples from two locations – a representative urban site in North Tyneside and rural site in Oxfordshire – alongside foods sampled from retail in York, Salisbury and London.
With regards to antimicrobial resistance, the study revealed a rise in fluoroquinolone and tetracycline resistance in C.jejuni isolates from human infections between 1997 and 2018. Fluoroquinolone resistance was more frequent in C.jejuni isolates from chicken than from other animals, whilst tetracycline resistance was more frequent in poultry and pig isolates than ruminants. Resistance to macrolides and aminoglycosides remain low.
The majority of people who are infected with Campylobacter recover fully and quickly, but it can cause long-term and severe health problems in some, including young children and the elderly.
You can help keep your family safe by cooking your food correctly, and avoiding cross-contamination through ensuring good personal hygiene.

Record levels of Campylobacter and Salmonella have been recorded in Australia, according to the annual surveillance report of notifiable diseases for 2016.
The data comes from a study published in the most recent edition of the Communicable Diseases Intelligence journal that also found E. coli, Listeria and Cryptosporidium infections had risen.
The role of disease surveillance includes identifying national trends, providing guidance for policy development and resource allocation and informing the response to outbreaks, according to the researchers.
In 2016, gastrointestinal diseases made up 15 percent of total reports for communicable diseases. Notified cases increased by 10 percent to 49,885 in 2016 compared to 2015.
