Limit your use of antibiotics

Use antibiotics when only if it’s necessary.
If you have to use antibiotics, ensure you always complete the course. This is because resistant fighters who are less skilled will eventually give up and be eliminated. The only bacteria that remain are the ones that wouldn’t have been killed by antibiotics anyway.

Choose organically farmed meat.
In countries like India or Spain, there is almost no regulation on the number of antibiotics given to animals. This leads to animals being the breeding ground of antibiotic-resistant bacteria. People in those regions have more infections with multi-drug-resistant bacteria strains. Making sure your meat is organically farmed makes exposure to antibiotic-resistant animals much less likely.

Wash fruit and vegetables thoroughly.
Animal feces are popular fertilizer for vegetable fields. In many countries, fruits and vegetables are not routinely tested for multi-drug-resistant gut bacteria. Washing them will eliminate any residual bits of antibiotics that could help bad bacteria develop resistance.

Take care abroad.
One in four travelers returns home carrying highly resistant bacteria. Most disappear in a couple of months, but some can stick for a lot longer. You should wash your hand regularly, clean fruit and vegetables thoroughly, and even use boiling water. “Cook it, peel it, or leave it” is a good role of thumb for avoiding diarrhea and protecting your family from unwanted bacterial guests.
