Growth in today’s dairies has led to increasing dependence on Latino immigrant workers. Shortage of qualified personnel prompts owners to assign training to tenured employees which can perpetuate bad habits. New educational trainings to improve dairy practices are required. The aim was to create similar training courses used by other industries, with a strategic approach to environmental sustainability, animal health and wellbeing, milk quality, and workers’ health. “Dairy Tool Box Talks” program was conducted over 10-week period in Spanish at 3 SD dairies. Employees (n = 75) involved in milking operations had weekly talks included a 1-h cattle handling demonstration and 9 30-min classroom trainings covering basics understanding of animal care and employee safety. Throughout this period bulk tank milk was tested for milk quality. To evaluate the employees understanding a final group assessment was conducted at wk 10 using Turning Technologies. Average daily milk yield was 33 kg/cow and bulk milk SCC ranged from 159,000 to 270,000 cells/mL with a significant increase (P < 0.001) expected by the season (summer). Coliforms did not differ by farm (4.48, 3.54 and 3.74 log cfu/mL for farms A, B and C; respectively); however, there were lower counts during the last 4 weeks (P < 0.05; 3.21, 2.78 and 0.77 log cfu/mL for farms A, B and C; respectively), suggesting improved hygiene practices. The trainings resulted in significant outcomes from a better understanding of farming practices to a higher milk quality harvested throughout the study. Nearly 85% agreed sessions helped with job confidence and 76% considered the program length adequate as well as the topics. Furthermore, 95% desired more involvement during sessions from farm management. Positive changes in employee behavior, better working relations and hygiene awareness were noted during the employer’s interview. These changes should increase employee’s productivity, reduce costly and even fatal farm accidents and improve employee retention. The sessions were highly effective since they were offered in the workers’ native language and were tailored to weekly single topic trainings.
