Measures to Contribute to the Prevention and Control of Covid-19 in the Milk Production Chain

ABSTRACT: The Zona da Mata of Minas Gerais has a specialized goat milk production chain. Goat milk is superior in quality compared with milk of other domestic species, and the demand for milk and milk products for the public has increased. Data on dairy goat breeding in Minas Gerais are scarce and relatively old, and this lack of information has limited the implementation of prophylactic measures, especially for mastitis, which represents the biggest sanitary problem for dairy herds. The objective of this work was to characterize mastitis and bacteria associated with it in milking goats in the Zona da Mata of Minas Gerais. It also causes socioeconomic problems and market issues for dairy goat farming. A total of 539 lactating goats were examined and 268 individual samples (one for teat) were collected from animals positive for strip cup test and/or the California Mastitis Test (CMT). Microbiological cultures were carried out on blood agar medium and the bacteria were subjected to phenotypic, genotypic and antimicrobial susceptibility tests. The prevalence of subclinical mastitis was 28.0% and the clinical prevalence was 2.8%. Bacterial multiplication was obtained in 62% of samples. One hundred eighty seven total bacteria were identified. The most common species identified was Staphylococcus aureus (60%), followed Staphylococcus epidermidis (9.1%,), Escherichia coli (6.9%), Staphylococcus saprophyticus (5.9%) e Staphylococcus caprae (4.3%). Bacteria of the genus Staphylococcus presented a profile of resistance to antimicrobials belonging to the beta-lactam class (penicillin, ampicillin and oxacillin) in addition to tetracycline, in contrast to the other antimicrobials tested. Twelve percent of multidrug resistence (MDR) was found in five microregions. Among the bacteria with the highest prevalence of MDR, 38.5% were E. coli and 10.6% were S. aureus. The producers of the Zona da Mata of Minas Gerais are technicians who work with specialized dairy breeds and practise good management. However, some measures related to prophylaxis and control of diseases, such as vaccination, have low adherence or are not performed due to a lack of veterinary assistance. This is the first study focusing on this region, which is highly prominent in goat milk production in Brazil. It provides important information that can help in the implementation of measures for the prophylaxis and control of diseases, and for maintenance of a constant supply of products in sufficient quantities and of a quality suitable for the consumer population.

West Java has been conducting Policy of Large-Scale of Social Restriction (in bahasa Pembatasan Sosial Berskala Besar or PSBB). However several companies in wide range of industries are allowed to run the production with health protocol that need to be fulfilled by company in order to keep the worker’s health during this pandemic. One of manufacturing companies with 307 workers in Bekasi Regency is still running the production as part of food production chain. As Indonesian Health Ministry Guidelines for Prevention and Control COVID-19 at Office and Industry Workplace during Policy of PSBB need to be fulfilled, the company implements several actions to protect the worker from COVID-19 at workplace environment. At this moment, safety and health management commitment need to be assessed making sure implementation of the guidelines. In order to make sure COVID-19 prevention, there must be implementation evaluation of Guidelines for Prevention and Control of COVID-19 at Office and Industry Workplace during PSBB Policy. Study shows although the finding of low level safety and health management commitment from worker’s perception, majority Guidelines for Prevention COVID-19 at Office and Industry Workplace during PSBB that focus for workplace environment have been facilitated by the management of company.

And Control

Microbial monitoring of broiler production can provide an important theoretical basis for the prevention and control of animal diseases and reduce the pollution of the environment. In order to investigate the contamination and spread of Campylobacter jejuni in broiler production chain, we collected samples from the broiler farms, slaughterhouse and market of a big production chain in Qingdao, isolated and identified of Campylobacter jejuni. Then we used genotyping method to subtype the isolates. The result showed that C.jejuni were widespread in broiler pruduction chain, and the strains can spread during the production chain, so strengthen the scientific management of the production chain must be implemented. Control in the feeding, processing and preparation before eating of chicken are the important measures in reducing the Campylobacter jejuni infections caused by chicken.
